* [PATCH 3/4] arm64: dts: exynos: make tm2 and tm2e independent from each other

From: Andi Shyti <andi.shyti@samsung.com>
Currently tm2e dts includes tm2 but there are some differences
between the two boards and tm2 has some properties that tm2e
doesn't have.
That's why it's important to keep the two dts files independent
and put all the commonalities in a tm2-common.dtsi file.

In-Reply-To: <1483430237-26823-1-git-send-email-jcsing.lee@samsung.com>
This patch adds support for the TM2 touch key and led
functionlity.
The driver interfaces with userspace through an input device and
reports KEY_PHONE and KEY_BACK event types. LED brightness can be
controlled by "/sys/class/leds/tm2-touchkey/brightness".

Hi,
This patchset adds support for the tm2 touchkey device.
The driver has been ported from Tizen Kernel, originally written
by Beomho. I ported it to the latest mainline Kernel.
dts has been separated between tm2 and tm2e because touchkey is present in tm2
but not tm2e.
Best Regards,
Jaechul

I think keeping the newline makes it more clear in structure. But I also understand
your point - no newline inside one property, right? If so I will delete the newline.

We can treat regulatory and OF data as entirely independent, I think.
At least that's my suggestion:
* use OF data to populate the original channel list, saying which
channels are valid (or not)
* use regulatory later to further restrict settings of the channels

I think maybe there's a problem in my understanding :)
All the regulatory code usually takes into account channel->orig_flags.
If this code also did, then we could have the original DISABLED flag
taken from OF still be valid here.

The subject prefix is still not so right. There should be a space after
each colon.

The single line comment format is /* blabla */. There are space at both
beginning and end of the text.
Also I am asking that we use the single line comment to replace the
blank line, which is still there.

No, because of the shared channel data issue. If this is
unconditionally in wiphy_register() then we can no longer guarantee
that sharing it is acceptable - which it is today under certain
circumstances the driver controls. This would move it out of driver
control, making it never possible to share any more.

Yeah, whatever :)
We can figure that out once we have the mechanisms in place.

Perhaps making adi,idle-state an array of tuples <mux-number state> and
add adi,idle-high-impedance as an array of mux-numbers, so that my example
above would come out as:
adi,idle-high-impedance = <1>; /* mux 1 idles with high imp */
adi,idle-state = <2 0>; /* mux 2 idles in state 0 (signal A) */
mux 0 is not mentioned and idles in its previously selected state.
If you want mux 0 to idle with high impedance:
adi,idle-high-impedance = <0 1>;
adi,idle-state = <2 0>;
If you want mux 0 to idle with signal C:
adi,idle-high-impedance = <1>;
adi,idle-state = <0 3>, <2 0>;

Previously the onboard hub was made to work by treating its
reset gpio as a regulator enable.
Get rid of that kludge now that pwseq has added reset gpio support
Move pin muxing the hub reset pin into the usbh1 group

The current dts describes USB HUB's property at USB controller's
entry, it is improper. The USB HUB should be the child node
under USB controller, and power sequence properties are under
it. Besides, using gpio pinctrl setting for USB2415's reset pin.

At device tree, we have no device node for chipidea core,
the glue layer's node is the parent node for host and udc
device. But in related driver, the parent device is chipidea
core. So, in order to let the common driver get parent's node,
we let the core's device node equals glue layer device node.

Some hard-wired USB devices need to do power sequence to let the
device work normally, the typical power sequence like: enable USB
PHY clock, toggle reset pin, etc. But current Linux USB driver
lacks of such code to do it, it may cause some hard-wired USB devices
works abnormal or can't be recognized by controller at all.
In this patch, it calls power sequence library APIs to finish
the power sequence events. It will do power on sequence at hub's
probe for all devices under this hub (includes root hub).
At hub_disconnect, it will do power off sequence which is at powered
on list.

In-Reply-To: <1483425211-14473-1-git-send-email-peter.chen@nxp.com>
We have an well-known problem that the device needs to do some power
sequence before it can be recognized by related host, the typical
example like hard-wired mmc devices and usb devices.
This power sequence is hard to be described at device tree and handled by
related host driver, so we have created a common power sequence
library to cover this requirement. The core code has supplied
some common helpers for host driver, and individual power sequence
libraries handle kinds of power sequence for devices. The pwrseq
librares always need to allocate extra instance for compatible
string match.
pwrseq_generic is intended for general purpose of power sequence, which
handles gpios and clocks currently, and can cover other controls in
future. The host driver just needs to call of_pwrseq_on/of_pwrseq_off
if only one power sequence is needed, else call of_pwrseq_on_list
/of_pwrseq_off_list instead (eg, USB hub driver).
For new power sequence library, it can add its compatible string
to pwrseq_of_match_table, then the pwrseq core will match it with
DT's, and choose this library at runtime.

+The generic power sequence library
+
+Some hard-wired devices (eg USB/MMC) need to do power sequence before
+the device can be enumerated on the bus, the typical power sequence
+like: enable USB PHY clock, toggle reset pin, etc. But current
+Linux device driver lacks of such code to do it, it may cause some
+hard-wired devices works abnormal or can't be recognized by
+controller at all. The power sequence will be done before this device
+can be found at the bus.
+
+The power sequence properties is under the device node.
+
+Optional properties:
+- clocks: the input clocks for device.
+- reset-gpios: Should specify the GPIO for reset.
+- reset-duration-us: the duration in microsecond for assert reset signal.
+
+Below is the example of USB power sequence properties on USB device
+nodes which have two level USB hubs.
+
+&usbotg1 {
+ vbus-supply = <®_usb_otg1_vbus>;

Hi all,
This is a follow-up for my last power sequence framework patch set [1].
According to Rob Herring and Ulf Hansson's comments[2]. The kinds of
power sequence instances will be added at postcore_initcall, the match
criteria is compatible string first, if the compatible string is not
matched between dts and library, it will try to use generic power sequence.
The host driver just needs to call of_pwrseq_on/of_pwrseq_off
if only one power sequence instance is needed, for more power sequences
are used, using of_pwrseq_on_list/of_pwrseq_off_list instead (eg, USB hub driver).
In future, if there are special power sequence requirements, the special
power sequence library can be created.
This patch set is tested on i.mx6 sabresx evk using a dts change, I use
two hot-plug devices to simulate this use case, the related binding
change is updated at patch [1/6], The udoo board changes were tested
using my last power sequence patch set.[3]
Except for hard-wired MMC and USB devices, I find the USB ULPI PHY also
need to power on itself before it can be found by ULPI bus.

[3] http://www.spinics.net/lists/linux-usb/msg142815.html
Changes for v11:
- Fix warning: (USB) selects POWER_SEQUENCE which has unmet direct dependencies (OF)
- Delete redundant copyright statement.
- Change pr_warn to pr_debug at wrseq_find_available_instance
- Refine kerneldoc
- %s/ENONET/ENOENT
- Allocate pwrseq list node before than carry out power sequence on
- Add mutex_lock/mutex_lock for pwrseq node browse at pwrseq_find_available_instance
- Add pwrseq_suspend/resume for API both single instance and list
- Add .pwrseq_suspend/resume for pwrseq_generic.c
- Add pwrseq_suspend_list and pwrseq_resume_list for USB hub suspend
and resume routine
Changes for v10:
- Improve the kernel-doc for power sequence core, including exported APIs and
main structure. [Patch 2/8]
- Change Kconfig, and let the user choose power sequence. [Patch 2/8]
- Delete EXPORT_SYMBOL and change related APIs as local, these APIs do not
be intended to export currently. [Patch 2/8]
- Selete POWER_SEQUENCE at USB core's Kconfig. [Patch 4/8]
Changes for v9:
- Add Vaibhav Hiremath's reviewed-by [Patch 4/8]
- Rebase to v4.9-rc1
Changes for v8:
- Allocate one extra pwrseq instance if pwrseq_get has succeed, it can avoid
preallocate instances problem which the number of instance is decided at
compile time, thanks for Heiko Stuebner's suggestion [Patch 2/8]
- Delete pwrseq_compatible_sample.c which is the demo purpose to show compatible
match method. [Patch 2/8]
- Add Maciej S. Szmigiero's tested-by. [Patch 7/8]
Changes for v7:
- Create kinds of power sequence instance at postcore_initcall, and match
the instance with node using compatible string, the beneit of this is
the host driver doesn't need to consider which pwrseq instance needs
to be used, and pwrseq core will match it, however, it eats some memories
if less power sequence instances are used. [Patch 2/8]
- Add pwrseq_compatible_sample.c to test match pwrseq using device_id. [Patch 2/8]
- Fix the comments Vaibhav Hiremath adds for error path for clock and do not
use device_node for parameters at pwrseq_on. [Patch 2/8]
- Simplify the caller to use power sequence, follows Alan's commnets [Patch 4/8]
- Tested three pwrseq instances together using both specific compatible string and
generic libraries.
Changes for v6:
- Add Matthias Kaehlcke's Reviewed-by and Tested-by. (patch [2/6])
- Change chipidea core of_node assignment for coming user. (patch [5/6])
- Applies Joshua Clayton's three dts changes for two boards,
the USB device's reg has only #address-cells, but without #size-cells.
Changes for v5:
- Delete pwrseq_register/pwrseq_unregister, which is useless currently
- Fix the linker error when the pwrseq user is compiled as module
Changes for v4:
- Create the patch on next-20160722
- Fix the of_node is not NULL after chipidea driver is unbinded [Patch 5/6]
- Using more friendly wait method for reset gpio [Patch 2/6]
- Support multiple input clocks [Patch 2/6]
- Add Rob Herring's ack for DT changes
- Add Joshua Clayton's Tested-by
Changes for v3:
- Delete "power-sequence" property at binding-doc, and change related code
at both library and user code.
- Change binding-doc example node name with Rob's comments
- of_get_named_gpio_flags only gets the gpio, but without setting gpio flags,
add additional code request gpio with proper gpio flags
- Add Philipp Zabel's Ack and MAINTAINER's entry
Changes for v2:
- Delete "pwrseq" prefix and clock-names for properties at dt binding
- Should use structure not but its pointer for kzalloc
- Since chipidea core has no of_node, let core's of_node equals glue
layer's at core's probe

Different subsystem or binding examples use different style, but when we
put things together in the platform dts, we would like to have them in a
unified style.
