Merge tag 'ib-mfd-extcon-hid-i2c-iio-input-media-chrome-power-pwm-rtc-sound-v5.4' into chrome-platform/for-next

Immutable branch between MFD, Extcon, HID, I2C, IIO, Input, Chrome, Power,
PWM, RTC and Sound to allow picking patches that depends on the series
that moves some code from the MFD subsystem to platform/chrome.
