From: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org>
IMX290 operates with multiple link frequency and pixel rate combinations.
The initial driver used a single setting for both but since we now have
the lane count support in place, let's add configurable link frequency
and pixel rate.

This macro is defined as SET_RUNTIME_PM_OPS(suspend_fn, resume_fn, idle_fn),
so imx290_power_off must be the 1st arg, and imx290_power_on the 2nd.

* [PATCH v3 03/10] media: i2c: imx290: fix reset GPIO pin handling

According to https://www.kernel.org/doc/Documentation/gpio/consumer.txt,
- all of the gpiod_set_value_xxx() functions operate with the *logical* value.
So in imx290_power_on() the reset signal should be cleared/de-asserted with
gpiod_set_value_cansleep(imx290->rst_gpio, 0), and in imx290_power_off() the
value of 1 must be used to apply/assert the reset to the sensor. In the device
tree the reset pin is described as GPIO_ACTIVE_LOW, and gpiod_set_value_xxx()
functions take this into account,
- when devm_gpiod_get_optional() is called with GPIOD_ASIS, the GPIO is not
initialized, and the direction must be set later; using a GPIO
without setting its direction first is illegal and will result in undefined
behavior. Fix this by using GPIOD_OUT_HIGH instead of GPIOD_ASIS (this asserts
the reset signal to the sensor initially).

With the current driver 'media-ctl -p' issued right after the imx290 driver
is loaded prints:
pad0: Source
[fmt:unknown/0x0]
The format value of zero is due to the current_format field of the imx290
struct not being initialized yet.
As imx290_entity_init_cfg() calls imx290_set_fmt(), the current_mode field
is also initialized, so the line which set current_mode to a default value
in driver's probe() function is no longer needed.

* [PATCH v3 00/10] Improvements to IMX290 CMOS driver
From: Andrey Konovalov @ 2020-05-24 19:24 UTC (permalink / raw)

This patchset adds improvements to the existing media driver for IMX290
CMOS sensor from Sony. The major changes are adding 2 lane support,
configurable link frequency & pixel rate, test pattern generation, and
RAW12 mode support.
The link frequency & pixel rate combinations depend on various factors like
lane count, resolution and image format as per the datasheet.
Also fixes for the following issues in the existing driver are included:
* the current_format field in the struct imx290 can be used before
initialization,
* the reset signal to IMX290 isn't handled correctly,
* the bus_type field of v4l2_fwnode_endpoint structure passed as the
argument to v4l2_fwnode_endpoint_alloc_parse() function is not
initiaized.
Changes in v3:
* The review comments from Sakari are addressed
https://lkml.org/lkml/2019/12/19/705
As a part of those changes:
. null ptr checks are added to imx290_set_fmt() so that it can be called
early in the probe() function to set the default format, and to
initialize imx290->current_mode and imx290->bpp - these last two must be
set before imx290_calc_pixel_rate() is called when creating the controls
. setting imx290->bpp removed from imx290_write_current_format(). Now this
function only writes to the camera sensor registers. The call to
imx290_write_current_format() is moved from imx290_set_fmt() back to
imx290_start_streaming(): imx290_set_fmt() can be called when the sensor
is powered off, and writes to the sensor registers would fail.
. in imx290_set_ctrl() in the 12 bpp case the value the BLKLEVEL register
is restored to when the test pattern is disabled is made consistent with
imx290_12bit_settings[]
* The "IMX290 sensor driver fixes" patchset included
https://patchwork.kernel.org/cover/11407347/
* Added a patch to set the bus_type field of v4l2_fwnode_endpoint structure
before calling v4l2_fwnode_endpoint_alloc_parse()
Andrey Konovalov (4):
media: i2c: imx290: set the format before VIDIOC_SUBDEV_G_FMT is
called
media: i2c: imx290: fix the order of the args in SET_RUNTIME_PM_OPS()
media: i2c: imx290: fix reset GPIO pin handling
media: i2c: imx290: set bus_type before calling
v4l2_fwnode_endpoint_alloc_parse()
Manivannan Sadhasivam (6):
media: i2c: imx290: Add support for 2 data lanes
media: i2c: imx290: Add configurable link frequency and pixel rate
media: i2c: imx290: Add support for test pattern generation
media: i2c: imx290: Add RAW12 mode support
media: i2c: imx290: Add support to enumerate all frame sizes
media: i2c: imx290: Move the settle time delay out of loop

Ok, please make sure to mask the value, so that it's explicit in the code that
we only use the lowest 5 bits of high_addr_reg_idx.

Please see patch 02/13:
http://lists.infradead.org/pipermail/linux-mediatek/2020-March/027801.html
Definitions begin with CMDQ_EVENT_ is the event id to this function.
Since the event id is different between platform, client must parse it
from device tree. So no magic values require when call this function.

Dennis

May I know which part not defined? The src_t defined on top of this
patch and CMDQ_REG_TYPE defined in last patc (see 06/13).

ok, I'll separate this function to cmdq_pkt_write_s and
cmdq_pkt_write_s_mask. Let the client choose which case is more
suitable.

The dst_t use in cmdq_pkt_assign function so how about merge other
variables to reserved and leave dst_t ?
struct {
u8 reserved_t:7;
u8 dst_t:1;
};

* [PATCH 2/2] arm64: dts: rockchip: rename label and nodename pinctrl subnodes that end with gpio
From: Johan Jonker @ 2020-05-24 16:06 UTC (permalink / raw)
To: heiko; +Cc: robh+dt, devicetree, linux-arm-kernel, linux-rockchip,
linux-kernel
In-Reply-To: <20200524160636.16547-1-jbx6244@gmail.com>
A test with the command below gives for example this error:
arch/arm64/boot/dts/rockchip/rk3326-odroid-go2.dt.yaml:
tsadc: tsadc-otp-gpio:
{'phandle': [[90]], 'rockchip,pins': [[0, 6, 0, 123]]}
is not of type 'array'
'gpio' is a sort of reserved nodename and should not be used
for pinctrl in combination with 'rockchip,pins', so change
nodes that end with 'gpio' to end with 'pin' or 'pins'.
make ARCH=arm64 dtbs_check

* [PATCH 1/2] ARM: dts: rockchip: rename label and nodename pinctrl subnodes that end with gpio
From: Johan Jonker @ 2020-05-24 16:06 UTC (permalink / raw)
To: heiko; +Cc: robh+dt, devicetree, linux-arm-kernel, linux-rockchip,
linux-kernel
A test with the command below gives for example this error:
arch/arm/boot/dts/rk3288-tinker.dt.yaml: tsadc: otp-gpio:
{'phandle': [[54]], 'rockchip,pins': [[0, 10, 0, 118]]}
is not of type 'array'
'gpio' is a sort of reserved nodename and should not be used
for pinctrl in combination with 'rockchip,pins', so change
nodes that end with 'gpio' to end with 'pin' or 'pins'.
make ARCH=arm dtbs_check
DT_SCHEMA_FILES=~/.local/lib/python3.5/site-packages/
dtschema/schemas/gpio/gpio.yaml

* [PATCH v9 5/6] dt-bindings: clock: Add and reorder ABI for X1000.
From: 周琰杰 (Zhou Yanjie) @ 2020-05-24 15:47 UTC (permalink / raw)
To: linux-clk
Cc: linux-kernel, devicetree, sboyd, mturquette, robh+dt,
dongsheng.qiu, aric.pzqi, sernia.zhou, zhenwenjin, paul
In-Reply-To: <20200524154729.30958-1-zhouyanjie@wanyeetech.com>
1.The SSI clock of X1000 not like JZ4770 and JZ4780, they are not
directly derived from the output of SSIPLL, but from the clock
obtained by dividing the frequency by 2. "X1000_CLK_SSIPLL_DIV2"
is added for this purpose, it must between "X1000_CLK_SSIPLL"
and "X1000_CLK_SSIMUX", otherwise an error will occurs when
initializing the clock. These ABIs are only used for X1000, and
I'm sure that no other devicetree out there is using these ABIs,
so we should be able to reorder them.
2.Clocks of LCD, OTG, EMC, EFUSE, OST are also added.

* [PATCH v9 4/6] clk: Ingenic: Add CGU driver for X1830.
From: 周琰杰 (Zhou Yanjie) @ 2020-05-24 15:47 UTC (permalink / raw)
To: linux-clk
Cc: linux-kernel, devicetree, sboyd, mturquette, robh+dt,
dongsheng.qiu, aric.pzqi, sernia.zhou, zhenwenjin, paul
In-Reply-To: <20200524154729.30958-1-zhouyanjie@wanyeetech.com>
Add support for the clocks provided by the CGU in the Ingenic X1830
SoC, making use of the cgu code to do the heavy lifting.
Signed-off-by: 周琰杰 (Zhou Yanjie) <zhouyanjie@wanyeetech.com>
Reviewed-by: Paul Cercueil <paul@crapouillou.net>
---
Notes:
v1->v2:
1.Use two fields (pll_reg & bypass_reg) instead of the 2-values
array (reg[2]).
2.Remove the "pll_info->version" and add a "pll_info->rate_multiplier".
3.Change my Signed-off-by from "Zhou Yanjie <zhouyanjie@zoho.com>"
to "周琰杰 (Zhou Yanjie) <zhouyanjie@wanyeetech.com>" because
the old mailbox is in an unstable state.
v2->v3:
Adjust order from [4/5] in v2 to [5/5] in v3.
v3->v4:
Adjust order from [5/5] in v3 to [4/4] in v4.
v4->v5:
Rebase on top of kernel 5.6-rc1.
v5->v6:
Add missing part of X1830's CGU.
v6->v7:
1.Adjust includes, add blank line as Paul Cercueil's suggest.
2.Move "*cgu" into x1830_cgu_init() as a local variable.
v7->v8:
No change.
v8->v9:
Add Paul Cercueil's Reviewed-by, somehow his emails are not displayed
on the mailing list and patchwork of clock framework subsystem.

* [PATCH v9 6/6] clk: X1000: Add FIXDIV for SSI clock of X1000.
From: 周琰杰 (Zhou Yanjie) @ 2020-05-24 15:47 UTC (permalink / raw)
To: linux-clk
Cc: linux-kernel, devicetree, sboyd, mturquette, robh+dt,

In-Reply-To: <20200524154729.30958-1-zhouyanjie@wanyeetech.com>
1.The SSI clock of X1000 not like JZ4770 and JZ4780, they are not
directly derived from the output of SSIPLL, but from the clock
obtained by dividing the frequency by 2. "X1000_CLK_SSIPLL_DIV2"
is added for this purpose, and ensure that it initialized before
"X1000_CLK_SSIMUX" when initializing the clocks.
2.Clocks of LCD, OTG, EMC, EFUSE, OST, and gates of CPU, PCLK
are also added.
3.Use "CLK_OF_DECLARE_DRIVER" like the other CGU drivers.

Notes:
v5:
New patch.
V5->v6:
Add missing part of X1000's CGU.
v6->v7:
Update commit message.
v7->v8:
No change.
v8->v9:
Add Paul Cercueil's Reviewed-by, somehow his emails are not displayed
on the mailing list and patchwork of clock framework subsystem.
