[PATCH v3 0/4] leds: add leds-mt6323 support on MT7623 SoC

[sean.wang at mediatek.com]

From: Sean Wang <sean.wang at mediatek.com>

MT7623 SoC uses MT6323 PMIC as the default power supply
which has LED function insides. The patchset introduces
the LED support for MT6323 with on, off and hardware
dimmed and blinked and it should work on other similar
SoCs if also using MT6323.

Changes since v1:
- fixed typo in the comments
- sorted include directives alphabetically
- applied all register definitions with MT6323 prefix
- removed the redundant structure declaration
- fixed coding style defined in kernel doc format consistently
- added error handling into all the occurrences where regmap APIs
  are used
- removed loudly debug message
- made magic constant into meaningful macro
- added missing mutex_destroy when module removed called
- updated module license with GPL
- fixed sparse warnings

Changes since v2:
- fixed the typo in devicetree Documentation
- cleaned up the style and explanation in the comments
- applied all macro/struct/function definitions with MT6323 prefix
- put the logic about the setup from device tree into the function for simplicity
