From: ChiYuan Huang <cy_huang@xxxxxxxxxxx> The MediaTek 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. In MediaTek MT6370, there are four channel current-sink RGB LEDs that support hardware pattern for constant current, PWM, and breath mode. Isink4 channel can also be used as a CHG_VIN power good indicator. Signed-off-by: Alice Chen <alice_chen@xxxxxxxxxxx> Signed-off-by: ChiYuan Huang <cy_huang@xxxxxxxxxxx>

--- v6 - Remove the 'ko' from mt6370 led Kconfig description. - Add both authors for Alice and ChiYuan. - Use pdata to distinguish the code from mt6370/71 to mt6372. - Instead of 'state' define, use the 'state' enum. - Fix the typo for 'MT6372_PMW_DUTY'. - For pwm_duty define, replace with bit macro - 1. - Refine all the labels from 'out' to 'out_unlock'. - Use struct 'dev' variable and 'dev_err_probe' to optimize the LOC. - Revise for the array initialization from {0} to {}. - Move into rgb folder and rename file name to 'leds-mt6370-rgb'. - Refine the 'comma' usage in struct/enum. --- drivers/leds/rgb/Kconfig | 13 + drivers/leds/rgb/Makefile | 1 + drivers/leds/rgb/leds-mt6370-rgb.c | 1004 ++++++++++++++++++++++++++++++++++++ 3 files changed, 1018 insertions(+) create mode 100644 drivers/leds/rgb/leds-mt6370-rgb.c
