* kukui: Fix power leakage in LED.Yilun Lin2019-05-021-21/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Though setting the LED brighness to 0, LEDs are still sinking power. This causes power leakage (2mA) in G3 state. This CL turns off the LED current sinking if the LED brightness is set to 0. This also fixes LED not able to enter auto mode if it has been turned off previously.

* RT946x: Make mt6370_led_set_color accept composite colorsDaisuke Nojiri2019-02-091-8/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently, mt6370_led_set_color can handle only simple colors. That is, if a green LED is turned on, other LEDs are forced to be off. To allow composite colors (e.g. red+green), this change makes mt6370_led_set_color control LEDs independently. For example, to mix green and red, it can be called as mt6370_led_set_color(LED_MASK_GREEN | LED_MASK_RED); This is consistent with other RT946x LED APIs in the sense that they also control each LED independently.
