This patch series add MediaTek MT6370 LED indicator and flashlight support.
The MT6370 is a highly-integrated smart power management IC, which includes
a single cell Li-Ion/Li-Polymer switching battery charger, a
USB Type-C & Power Delivery (PD) controller, dual Flash LED current
sources, a RGB LED driver, a backlight WLED driver, a display bias
driver and a general LDO for portable devices.

First, in this series of patches,
- 'dt-binding: mfd' and 'mfd driver' have been applied by Lee in v7.
  https://lore.kernel.org/all/YvJdpq0MWNPQZw5c@google.com/
  https://lore.kernel.org/all/YvJdxEpC2cB58Bq9@google.com/

- 'tcpci driver' has been applied by Greg in v8.
  https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git/commit/?h=usb-next&id=c2a8ea5997fdfeb43eda259d5533234c3cae05d7

- 'dt-binding: backlight' and 'backlight driver' have been applied
  by Lee in v9.
  https://lore.kernel.org/all/YxYSDSlnOELL2mPF@google.com/
  https://lore.kernel.org/all/YxYS7%2FdZI69lMXeh@google.com/

- 'dt-binding: charger', 'charger driver' and 'linear_range.h' patch have
  been applied by Sebastian in v11.
  https://lore.kernel.org/all/20220920160857.6qfi66gtmgwesq7g@mercury.elektranox.org/
  https://lore.kernel.org/all/20220920161218.dkkfvfomrruebahi@mercury.elektranox.org/
  https://lore.kernel.org/all/20220920161238.dswtmyon462324dm@mercury.elektranox.org/

- 'dt-binding: leds: LED Indicator' and 'dt-binding: leds: LED Flash' have
  been applied by Rob in v12.
  https://lore.kernel.org/all/166480917702.2250974.12439864185418442009.robh@kernel.org/

- 'ADC driver' has been applied by Jonathan in v14.
  https://lore.kernel.org/all/20221015162217.41c4c112@jic23-huawei/

Second, the LED RGB driver is based on Andy's patch which moves
led_init_default_state_get() to the global header.
https://lore.kernel.org/all/20220805154907.32263-3-andriy.shevchenko@linux.intel.com/

In addition, we made some changes for MT6370 LED Flash Kconfig
(see v16 section of the change log below).

Change in v16:
- In Patch 1/2 (MT6370 LED Indicator)
	- Remove blank line in the head text.
	- Move 'pwm_duty' to descrease the size of struct mt6370_pdata.
	- Move the field 'F_RGB_EN' write out from if/else in
	  'mt6370_isnk_brightness_set'.
	- Remove 'dev' in struct mt6370_priv.
	- Remove the proprety reading for 'linux,default-trigger', led core
	  already did it.
	- Change the module license from 'GPL v2' to 'GPL'
	  In the head text, already deslcred SPDX license as 'GPL-2.0-only'.

- In Patch 2/2 (MT6370 Flash):
	- Remove blank line in the head text.
	- For enum, declared the first element as 0
	- Remove unusd default state and state define.
	- For mt6370_priv, 'dev' member only be used once. Remove it.
	- Refine assign operator for '?:', no need to use brackets for the
	  judgement.
	- Refine '_mt6370_flash_brightness_set' function for else case.
	- Modify 'struct led_flash_setting *setting' to 'struct
	  led_flash_setting *s'. This can reduce line count.
	- Remove the revert logic in 'mt6370_strobe_set' function.
	  No need to do it.
	- Remove mutex usage in timeout_set and fault_get.
	  Regmap lock already protect it.
	- Add default label for switch case in fault_get.
	- Directly assign fwnode as the parameter for 'mt6370_led_register' and
	  'mt6370_init_flash_config'.
	- Due to struct mt6370_priv 'dev' member removed, pass 'dev' as the
	  input parameter for 'mt6370_init_flash_config'.
	- For some if judgement, remove 'num > MT6370_MAX_LEDS'.
	  There's no need to check it. The below code already protect it.
	- Group mt6360 and mt6370 in Makefile.
	- SPDX already declared as 'GPL v2-only', change MODULE_LICENSE to
	  'GPL'.
	- Add one more author for ChiYuan Huang.
