[PATCH 0/4] pwm: add support for ChromeOS EC PWM

Show all headers | View raw

Hi,

This series adds support for the new ChromeOS EC PWM API, so we can control,
e.g., the backlight when it's attached to the EC. It uses Boris's latest
"atomic" hooks for the PWM API (i.e., the ->apply() callback), which were
recently merged.

It seems nice to have the cros_ec_cmd_xfer_status() helper, which we have
locally in the ChromeOS kernel, and which has been part of another larger patch
series:

https://lkml.org/lkml/2016/4/12/342

So I've picked it into this series as well. Obviously, I don't care which one
is taken, but AFAICT, Tomeu's USB PD series isn't extremely active right now.

As this touches MFD (sort of), drivers/platform/chrome/, and drivers/pwm/, I'm
not sure who it should all go through: Lee, Thierry, or Olof?

Anyway, please review.

Regards,
Brian
