[PATCH 0/8] Add WLED support to TPS68470 LED driver

[Daniel Scally <dan.scally@ideasonboard.com>]

This series relies on the recent "leds: tps68470: LED driver for TPS68470" set
from Kate Hsuan [1]

The TPS68470 provides two additional LED outputs on top of the indicator LEDs.
Add support for those to the driver. The configuration of the chip is drawn from
platform data which is expected to be passed to the driver. Additionally update
the int3472-tps68470 driver to register led lookups from platform data so that
the right LED is driven for each sensor, and finally define those lookups for
the Microsoft Surface Go line.

Kate, Hans, this is the changes I made on top of the tps68470-led series to
enable the IR LED on my Go2 (plus one additional patch to media). #5 could
probably just be squashed into the other series though. The last two patches
cover how I think the LED lookup should work - I unfortunately can't see an
automatic way to guarantee the right LED goes to the right sensor.

Thanks
Dan
