The first patch updates the device tree bindings for leds-qcom-lpg to
include support for PMI8950 PWM.
The second patch adds a pwm node to the device tree for the PMI8950. This
node is found on some msm8953 devices, such as the Xiaomi Mido, and its
inclusion in the device tree will enable infrared LED functionality on
these devices.
The final patch adds support for the PMI8950 PWM to the leds-qcom-lpg
driver.
The PMI8950 PMIC contains one PWM channel.

Oddly enough, there's also 1 LPG channel on the PM(not I)8950 @ 0xbc00
