* [PATCH v6 5/9] iio: adc: at91-sama5d2_adc: add support for position and pressure channels

In-Reply-To: <1526898477-9952-1-git-send-email-eugen.hristev@microchip.com>
This implements the support for position and pressure for the included
touchscreen support in the SAMA5D2 SOC ADC block.
Two position channels are added and one for pressure.
They can be read in raw format, or through a buffer.
A normal use case is for a consumer driver to register a callback buffer
for these channels.
When the touchscreen channels are in the active scan mask,
the driver will start the touchscreen sampling and push the data to the
buffer.
Some parts of this patch are based on initial original work by
Mohamed Jamsheeth Hajanajubudeen and Bandaru Venkateswara Swamy

Changes in v6:
- fixed a crash when issuing buffer enable from sysfs, if no trigger was
previously configured. This is because now the driver can work in software
buffer mode (to connect the callback buffer). So, when trying to enable the
buffer, check if we are going indeed to a triggered mode or not. If not, do
not allow buffer to be started (we do not have the right trigger).
It's in buffer_postenable and predisable.
Changes in v4:
- use return value of at91_adc_configure_touch
- rewrote some part of the read_info_raw according to Jonathan's
suggestion
Changes in v3:
- prefix macros with AT91_SAMA5D2
- reworked the x_pos and y_pos functions into a single one with two
additional wrappers
- reworked pressure report to have it grow naturally and not top down
- fixed some checks regarding IIO_VOLTAGE as suggested
- added a comment explaining some code in trigger handling
- reworked the frequency get handler to use the saved value instead of
reading it from the hardware.
- added comment on deffered work queueing
- pulled out INFO_RAW function into a separate utility function as suggested
- added iio_dev ops structure at all times . The functions are needed in
case we do not have a hardware trigger attached, but we want to use the
consumer touchscreen driver, thus a callback buffer is attached. Then we still
need to have buffer preenable and postdisable to configure the touch IRQs (etc.)
Changes in v2:
- the support is now based on callback buffer.

* [PATCH v6 6/9] input: touchscreen: resistive-adc-touch: add generic resistive ADC touchscreen
From: Eugen Hristev @ 2018-05-21 10:27 UTC (permalink / raw)
To: jic23, ludovic.desroches, alexandre.belloni, linux-arm-kernel,
devicetree, linux-kernel, linux-iio, linux-input, nicolas.ferre,
dmitry.torokhov, robh
Cc: Eugen Hristev
In-Reply-To: <1526898477-9952-1-git-send-email-eugen.hristev@microchip.com>
This adds a generic resistive touchscreen (GRTS) driver, which is based
on an IIO device (an ADC). It must be connected to the channels of an ADC
to receive touch data. Then it will feed the data into the input subsystem
where it registers an input device.
It uses an IIO callback buffer to register to the IIO device
Some parts of this patch are based on initial original work by
Mohamed Jamsheeth Hajanajubudeen and Bandaru Venkateswara Swamy
Signed-off-by: Eugen Hristev <eugen.hristev@microchip.com>

Changes in v6:
- changed a dev_err to dev_dbg which was forgotten in v5.
Changes in v5:
- return error on probe if failed add_action_or_reset
- renamed property touchscreen-threshold-pressure to
touchscreen-min-pressure, changed variables accordingly
Changes in v4:
- added a small description in file header
- changed MAX_POS_MASK to GRTS_MAX_POS_MASK
- initialized press with 0, as this value means no touch.
press has to be initialized because compiler/checkpatch complains
that can be used uninitialized.
- changed of_property_read_u32 to device_*
- set_abs_params for pressure will have range according to threshold
- changed evbit and keybit with set_capability call
- changed variable names to error instead of ret
- checked errors for add_action_or_reset
- cosmetic cleaning
Changes in v3:
- pressure now reported naturally growing down-up
- using helpers from touchscreen.h to parse DT properties
- added devm_add_action_or_reset to handle callback buffer clean on exit
- changed compatible and threshold property to adapt to changed bindings
Changes in v2:
- this is now a generic resistive adc touchscreen driver

* [PATCH] cpufreq: Add Kryo CPU scaling driver
From: Ilia Lin @ 2018-05-21 10:31 UTC (permalink / raw)
To: viresh.kumar
Cc: linux-clk, devicetree, linux-kernel, linux-pm, linux-arm-msm,
linux-soc, linux-arm-kernel
In-Reply-To: <1526555955-29960-11-git-send-email-ilialin@codeaurora.org>
In Certain QCOM SoCs like apq8096 and msm8996 that have KRYO processors,
the CPU frequency subset and voltage value of each OPP varies
based on the silicon variant in use. Qualcomm Process Voltage Scaling Tables
defines the voltage and frequency value based on the msm-id in SMEM
and speedbin blown in the efuse combination.
The qcom-cpufreq-kryo driver reads the msm-id and efuse value from the SoC
to provide the OPP framework with required information.
This is used to determine the voltage and frequency value for each OPP of
operating-points-v2 table when it is parsed by the OPP framework.

Yes, I acked it earlier, but then comments came back. You should drop
the tags in such cases normally.
Anyway, the patch looks fine now.

$ grep -R "of_reset_n_cells = [^1]" drivers/reset/
drivers/reset/reset-berlin.c: priv->rcdev.of_reset_n_cells = 2;
drivers/reset/hisilicon/reset-hi3660.c: rc->rst.of_reset_n_cells = 2;
drivers/reset/reset-ti-sci.c: data->rcdev.of_reset_n_cells = 2;
drivers/reset/reset-lantiq.c: priv->rcdev.of_reset_n_cells = 2;
everything else uses only one reset cell
from the lantiq reset dt-binding documentation: "The first cell takes
the reset set bit and the second cell takes the status bit."
I'm not sure what to do with drivers that specify != 1 reset-cell
though if we use a simple "init state pair"
maybe Philipp can share his opinion on this one as well

I believe we need to keep this if there's hardware out there:
- where the reset controller only supports reset pulses
- at least one reset line is shared between multiple devices
I didn't have a closer look at the Amlogic Meson6 SoC yet, but I think
it matches above criteria. as far as I know:
- the USB situation there is similar to Meson8b (USB controllers and
PHYs share a reset line)
- it uses an older reset controller IP block which does not support
level resets (only reset pulses)

get_cpu_device() takes the logical CPU number. So the above gets CPU 0
each time, and so cpu_dev_silver == cpu_dev_gold here. So what's the
point of the second get_cpu_device() ? If it's supposed to be:
cpu_dev_gold = get_cpu_device(GOLD_LEAD);
That would get CPU 2, but in terms of these defines, it doesn't make that
much sense. What exactly does "silver lead" and "gold lead" refer to in
these definitions?

Given that cpu_dev_silver == cpu_dev_gold, doesn't the second call to
dev_pm_opp_set_supported_hw() always fail, as opp_table->supported_hw
will be set by the first call?
To me, this driver looks completely useless as it will always fail to
initialise, and I question whether this code has even been runtime
tested.

Indeed, my bad.
Shouldn't you however use "adi,adv7180cp" as that's the chip we are using ?
The "adi,adv7180" has no port documented in its DT bindings, so it shouldn't
have any port node at all.

You are right.
cpu_dev_silver != cpu_dev_gold, and I found this with my tests as well.
Thank you.

* Tuned the HW configuration for clock frequencies below 600MHz
The series contains 4 groups of patches, which can be merged in the chain order,
while each group depends on all the previous groups.
(However, Only SOC, or SOC and Clocks, or SOC and Clocks and Cpufreq will work)
SOC (1/15):
Extracts the kryo l2 accessors driver from the QCOM PMU driver
Clocks (2/15-9/15):
This series adds support for the CPU clocks on msm8996 devices.
The driver uses the existing PLL drivers and is required to control
the CPU frequency scaling on the MSM8996.
Cpufreq (10/15-12/15):
The qcom-cpufreq-kryo driver is aimed to support different SOC versions.
The driver reads eFuse information and chooses the required OPP subset
by passing the OPP supported-hw parameter.
Regulators (13/15-15/15):
Added SAW regulator support to the SPMI regulator driver. The SAW regulators
will be controlled through special CPU registers instead of direct
SPMI accesses.
Ilia Lin (13):
soc: qcom: Separate kryo l2 accessors from PMU driver
clk: Use devm_ in the register fixed factor clock
clk: qcom: Add CPU clock driver for msm8996
dt-bindings: clk: qcom: Add bindings for CPU clock for msm8996
clk: qcom: cpu-8996: Add support to switch below 600Mhz
clk: qcom: Add ACD path to CPU clock driver for msm8996
dt: qcom: Add opp and thermal to the msm8996
cpufreq: Add Kryo CPU scaling driver
dt-bindings: cpufreq: Document operating-points-v2-kryo-cpu
dt: qcom: Add qcom-cpufreq-kryo driver configuration
regulator: qcom_spmi: Add support for SAW
dt-bindings: qcom_spmi: Document SAW support
dt: qcom: Add SAW regulator for 8x96 CPUs
Rajendra Nayak (2):
clk: qcom: Make clk_alpha_pll_configure available to modules
clk: qcom: cpu-8996: Add support to switch to alternate PLL

In-Reply-To: <1526901932-9514-1-git-send-email-ilialin@codeaurora.org>
The driver provides kernel level API for other drivers
to access the MSM8996 L2 cache registers.
Separating the L2 access code from the PMU driver and
making it public to allow other drivers use it.
The accesses must be separated with a single spinlock,
maintained in this driver.

Use devm_clk_hw_register instead of clk_hw_register
to simplify the usage of this API. This way drivers that call
the clk_hw_register_fixed_factor won't need to maintain
a data structure for further cleanup.

* [PATCH v9 04/15] clk: qcom: Add CPU clock driver for msm8996
From: Ilia Lin @ 2018-05-21 11:25 UTC (permalink / raw)
To: mturquette, sboyd, robh, mark.rutland, viresh.kumar, nm,
lgirdwood, broonie, andy.gross, david.brown, catalin.marinas,

Cc: devicetree, linux-kernel, linux-pm, linux-arm-msm, linux-soc,

In-Reply-To: <1526901932-9514-1-git-send-email-ilialin@codeaurora.org>
Each of the CPU clusters (Power and Perf) on msm8996 are
clocked via 2 PLLs, a primary and alternate. There are also
2 Mux'es, a primary and secondary all connected together
as shown below
+-------+
XO | |
+------------------>0 |
| |
PLL/2 | SMUX +----+
+------->1 | |
| | | |
| +-------+ | +-------+
| +---->0 |
| | |
+---------------+ | +----------->1 | CPU clk
|Primary PLL +----+ PLL_EARLY | | +------>
| +------+-----------+ +------>2 PMUX |
+---------------+ | | | |
| +------+ | +-->3 |
+--^+ ACD +-----+ | +-------+
+---------------+ +------+ |
|Alt PLL | |
| +---------------------------+
+---------------+ PLL_EARLY
The primary PLL is what drives the CPU clk, except for times
when we are reprogramming the PLL itself (for rate changes) when
we temporarily switch to an alternate PLL. A subsequent patch adds
support to switch between primary and alternate PLL during rate
changes.
The primary PLL operates on a single VCO range, between 600MHz
and 3GHz. However the CPUs do support OPPs with frequencies
between 300MHz and 600MHz. In order to support running the CPUs
at those frequencies we end up having to lock the PLL at twice
the rate and drive the CPU clk via the PLL/2 output and SMUX.
So for frequencies above 600MHz we follow the following path
Primary PLL --> PLL_EARLY --> PMUX(1) --> CPU clk
and for frequencies between 300MHz and 600MHz we follow
Primary PLL --> PLL/2 --> SMUX(1) --> PMUX(0) --> CPU clk
Support for this is added in a subsequent patch as well.
ACD stands for Adaptive Clock Distribution and is used to
detect voltage droops.

Each of the CPU clusters (Power and Perf) on msm8996 are
clocked via 2 PLLs, a primary and alternate. There are also
2 Mux'es, a primary and secondary all connected together
as shown below
+-------+
XO | |
+------------------>0 |
| |
PLL/2 | SMUX +----+
+------->1 | |
| | | |
| +-------+ | +-------+
| +---->0 |
| | |
+---------------+ | +----------->1 | CPU clk
|Primary PLL +----+ PLL_EARLY | | +------>
| +------+-----------+ +------>2 PMUX |
+---------------+ | | | |
| +------+ | +-->3 |
+--^+ ACD +-----+ | +-------+
+---------------+ +------+ |
|Alt PLL | |
| +---------------------------+
+---------------+ PLL_EARLY
The primary PLL is what drives the CPU clk, except for times
when we are reprogramming the PLL itself (for rate changes) when
we temporarily switch to an alternate PLL. A subsequent patch adds
support to switch between primary and alternate PLL during rate
changes.
The primary PLL operates on a single VCO range, between 600MHz
and 3GHz. However the CPUs do support OPPs with frequencies
between 300MHz and 600MHz. In order to support running the CPUs
at those frequencies we end up having to lock the PLL at twice
the rate and drive the CPU clk via the PLL/2 output and SMUX.

Each of the CPU clusters on msm8996 are powered via a primary
PLL and a secondary PLL. The primary PLL is what drives the
CPU clk, except for times when we are reprogramming the PLL
itself, when we temporarily switch to an alternate PLL.
Use clock rate change notifiers to support this.

* [PATCH v9 07/15] clk: qcom: cpu-8996: Add support to switch below 600Mhz

The CPU clock controller's primary PLL operates on a single VCO range,
between 600MHz and 3GHz. However the CPUs do support OPPs with
frequencies between 300MHz and 600MHz. In order to support running the
CPUs at those frequencies we end up having to lock the PLL at twice the
rate and drive the CPU clk via the PLL/2 output and SMUX.
So for frequencies above 600MHz we follow the following path
Primary PLL --> PLL_EARLY --> PMUX(1) --> CPU clk
and for frequencies between 300MHz and 600MHz we follow
Primary PLL --> PLL/2 --> SMUX(1) --> PMUX(0) --> CPU clk

In-Reply-To: <1526901932-9514-1-git-send-email-ilialin@codeaurora.org>
The PMUX for each duplex allows for selection of ACD clock source.
The DVM (Dynamic Variation Monitor) will flag an error
when a voltage droop event is detected. This flagged error
enables ACD to provide a div-by-2 clock, sourced from the primary PLL.
The duplex will be provided the divided clock
until a pre-programmed delay has expired.
This change configures ACD during the probe and switches
the PMUXes to the ACD clock source.

* [PATCH v9 10/15] cpufreq: Add Kryo CPU scaling driver
From: Ilia Lin @ 2018-05-21 11:25 UTC (permalink / raw)

lgirdwood, broonie, andy.gross, david.brown, catalin.marinas,

In-Reply-To: <1526901932-9514-1-git-send-email-ilialin@codeaurora.org>
In Certain QCOM SoCs like apq8096 and msm8996 that have KRYO processors,
the CPU frequency subset and voltage value of each OPP varies
based on the silicon variant in use. Qualcomm Process Voltage Scaling Tables
defines the voltage and frequency value based on the msm-id in SMEM
and speedbin blown in the efuse combination.
The qcom-cpufreq-kryo driver reads the msm-id and efuse value from the SoC
to provide the OPP framework with required information.
This is used to determine the voltage and frequency value for each OPP of
operating-points-v2 table when it is parsed by the OPP framework.

In-Reply-To: <1526901932-9514-1-git-send-email-ilialin@codeaurora.org>
The qcom-cpufreq-kryo driver reads the msm-id and efuse value from the SoC
to provide the OPP framework with required information.
This is used to determine the voltage and frequency value for each OPP of
operating-points-v2 table when it is parsed by the OPP framework.
This change adds documentation for the DT bindings.
The "operating-points-v2-kryo-cpu" DT extends the "operating-points-v2"
with following parameters:
- nvmem-cells (NVMEM area containig the speedbin information)
- opp-supported-hw: A single 32 bit bitmap value,
representing compatible HW:
0: MSM8996 V3, speedbin 0
1: MSM8996 V3, speedbin 1
2: MSM8996 V3, speedbin 2
3: unused
4: MSM8996 SG, speedbin 0
5: MSM8996 SG, speedbin 1
6: MSM8996 SG, speedbin 2
7-31: unused

+Qualcomm Technologies, Inc. KRYO CPUFreq and OPP bindings
+===================================
+
+In Certain Qualcomm Technologies, Inc. SoCs like apq8096 and msm8996
+that have KRYO processors, the CPU ferequencies subset and voltage value
+of each OPP varies based on the silicon variant in use.
+Qualcomm Technologies, Inc. Process Voltage Scaling Tables
+defines the voltage and frequency value based on the msm-id in SMEM
+and speedbin blown in the efuse combination.
+The qcom-cpufreq-kryo driver reads the msm-id and efuse value from the SoC
+to provide the OPP framework with required information (existing HW bitmap).
+This is used to determine the voltage and frequency value for each OPP of
+operating-points-v2 table when it is parsed by the OPP framework.
+
+Required properties:
+--------------------
+In 'cpus' nodes:
+- operating-points-v2: Phandle to the operating-points-v2 table to use.
+
+In 'operating-points-v2' table:
+- compatible: Should be
+ - 'operating-points-v2-kryo-cpu' for apq8096 and msm8996.
+- nvmem-cells: A phandle pointing to a nvmem-cells node representing the
+ efuse registers that has information about the
+ speedbin that is used to select the right frequency/voltage
+ value pair.
+ Please refer the for nvmem-cells
+ bindings Documentation/devicetree/bindings/nvmem/nvmem.txt
+ and also examples below.
+
+In every OPP node:
+- opp-supported-hw: A single 32 bit bitmap value, representing compatible HW.
+ Bitmap:
+ 0: MSM8996 V3, speedbin 0
+ 1: MSM8996 V3, speedbin 1
+ 2: MSM8996 V3, speedbin 2
+ 3: unused
+ 4: MSM8996 SG, speedbin 0
+ 5: MSM8996 SG, speedbin 1
+ 6: MSM8996 SG, speedbin 2
+ 7-31: unused
