This patch series adds support for AWINIC AW20036/AW20054/AW20072 LED
driver programmed via an I2C interface.
This driver supports following AW200XX features:
- 3 pattern controllers for auto breathing or group dimming control
- Individual 64-level DIM currents
- Interrupt output, low active

+=========================================
+Kernel driver for AW20036/AW20054/AW20072
+=========================================
+
+Description
+-----------
+
+The AW20036/AW20054/AW20072 is a 3x12/6x9/6x12 matrix LED driver programmed via
+an I2C interface. The brightness of each LED is independently controlled by
+FADE and DIM parameter.
+
+Three integrated pattern controllers provide auto breathing or group dimming
+control. Each pattern controller can work in auto breathing or manual control
+mode. All breathing parameters including rising/falling slope, on/off time,
+repeat times, min/max brightness and so on are configurable.
+
+Device attribute
+-----------------------------------
+
+**/sys/class/leds/<led>/dim** - 64-level DIM current. If write negative value
+or "auto", the dim will be calculated according to the brightness.
+
+The configuration files for each pattern are located::
+
+ /sys/bus/i2c/devices/xxxx/pattern0/
+ /sys/bus/i2c/devices/xxxx/pattern1/
+ /sys/bus/i2c/devices/xxxx/pattern2/
+
+Directory layout example for pattern

+Timing parameters
+~~~~~~~~~~~~~~~~~
+
+- **on_time**
+
+- **rise_time**
+
+- **fall_time**
+
+- **off_time**
+
+See :ref:`auto_breath_mode`.
+
+Select from predefined times:
+
+.. flat-table::
+
+ * - Value
+ - Time (in seconds)
+ - Value
+ - Time (in seconds)
+
+ * - 0
+ - 0.00
+ - 8
+ - 2.1

+ - 0.51
+ - 12
+ - 5.2
+
+ * - 5
+ - 0.77

+ * - 6
+ - 1.04
+ - 14
+ - 7.3
+
+ * - 7
+ - 1.6
+ - 15
+ - 8.3
+
+Example set for rise-time=0.13s, on-time=0.26s,
+fall_time=6.2s, off_time=0.51s:
+
+.. code-block:: bash
+
+ echo 1 > rise_time
+ echo 2 > on_time
+ echo 13 > fall_time
+ echo 4 > off_time
+
+Maximum and minimum breathing Level
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+- **max_breathing_level**
+
+- **min_breathing_level**
+
+Loop
+~~~~~
+
+- **loop_begin** - choose where to start the loop:
+
+ .. flat-table::
+
+ * - Value
+ - Description
+
+ * - 0
+ - Begin from 'rise' state
+
+ * - 1
+ - Begin from 'on' state
+
+ * - 2
+ - Begin from 'fall' state
+
+ * - 3
+ - Begin from 'off' state
+
+- **loop_end_on** - write ``1`` loop end at 'on' state.
+
+- **repeat** - loop times. When write ``0``, the loop is end-less.
+
+Others
+~~~~~~
+
+- **clear_leds** - bitmask for clear leds to pattern.
+ For example clear leds 1, 2, 3, 4, 5, 7 (``10111110``):
+
+ .. code-block:: bash
+
+ echo be > clear_leds
+
+- **select_leds** - bitmask for set leds to pattern.
+ For example select leds 0, 3, 6, 7 (``11001001``):
+
+ .. code-block:: bash
+
+ echo c9 > select_leds
+
+- **mode** - pattern mode:
+ ``0`` - manual control, ``1`` - auto breathing
+
+- **start** - start/stop pattern:
+ ``0`` - to stop, ``1`` - to start
+
+- **toggle** - manual on/off control (see :ref:`manual_breath_mode`):
+ ``0`` - LEDs off, ``1`` - LEDs on
+
+- **ramp** - the smooth ramp up/down function (see :ref:`manual_breath_mode`):
+ ``0`` - disable, ``1`` - enable
+
+- **running** - Reading this file will return the pattern state:
+ ``1`` - is running, ``0`` - is finished (or not running)
+
+This file supports poll() to detect when the pattern finished.

You will have warning now. of_match_ptr goes with __maybe_unused. Drop it.

What does the "Driver" mean? Linux Driver? If yes, then drop it. Same in
other places.

Is it a standard property? Does not look like. Non-standard properties
need vendor prefix and type ($ref).

But judging by your constants, you have the same number of columns, just
rows differ, so probably you want to describe here number of rows.

No. Use existing properties from common.yaml. This looks like
led-max-microamp and it is per LED, not per entire device.

No. Bindings are not for storing register constants. Feel free to store
here IDs (ID start from 0 or 1 and is incremented by 1)... but how the
IMAX even matches any need for "ID"?

Drop all constants and instead use number of rows without specifying it
in binding.
So in total entire file can be dropped.

The AW200XX LED chip does not support imax setup per led.
Imax is the global parameter over the all leds. I suppose, it's better
to add vendor prefix or take minimum from all subnodes?
How do you think?

IMAX can be chosen from the predefined values in the
datasheet (10mA, 20mA, etc). Do you mean the IMAX should be round down
to nearest supported value in the driver?

Should I add it to Documentation/ABI/testing/sysfs-class-led-driver-aw200xx?
Is my understanding correct?
Is KernelVersion parameter required?

Unfortunately, it will not work. Because I want to calculate the whole
size of chip structure, it has flexible array member inside.

Have in mind that led-max-microamp is a required property in some cases,
so skipping it and using per-device properties does not solve the
problem of adjusting proper currents. What if each LED you set for
something which in total gives more than your imax?

What Linux driver support does not matter here. Bindings should reflect
hardware and the same time not store register constants but logical
values (for current this is in uA).

Krzysztof

You are right. From my point of view too, we must build our solutions from
HW capabilities. In the current situation, AW200XX chips support global
Imax value, so it's acceptable decision to use vendor prefix for global
imax parameter, why not?

And there was no proposal to go around HW capabilities. We talk only
about representation.

Jacek made his statement some time ago quite clear:
https://lore.kernel.org/all/5785F17D.3010108@samsung.com/
"If you question the idea of having different maximum brightness per
sub-LEDs controlled by the same device, then it means that you have
objections to the entire idea of LED subsystem max_brightness property,
whereas it has been broadly accepted and successfully used for years."

You really should take a look at pattern trigger. You should probably
use same API as it does, perhaps documenting which patterns this
particular driver can do in hardware.

You may want to submit driver without the hardware pattern support,
first.
