[PATCH 0/2] pwm: Add the Ingenic X1600 PWM controller

[Olivier Louvignes]

The Ingenic X1600 has a PWM controller of its own, separate from the TCU
timers that pwm-jz4740 drives on the earlier Ingenic SoCs. This adds its
binding and a driver built on the waveform callbacks.

Tested on a HiBy R1 (X1600), whose backlight is channel 0, through
pwm-backlight: brightness 1, 25, 50, 60 and 100% give the expected high and
low counts, 0 and 100% switch the channel off at the right idle level,
and an inversed 250 us of 1 ms on channel 1 reads back as INL 0, LOW
9375 then HIGH 28125 with the clock divided by 8. PWM_DEBUG stayed
silent.

The X1600 has no device tree upstream yet; its support is being posted
one subsystem at a time.
