[PATCH 0/2] MediaTek Helio X10 MT6795 - PWM driver

[AngeloGioacchino Del Regno]

In an effort to give some love to the apparently forgotten MT6795 SoC,
I am upstreaming more components that are necessary to support platforms
powered by this one apart from a simple boot to serial console.

This series introduces support for the PWMs found in Helio X10.

Tested on a Sony Xperia M5 (codename "Holly") smartphone.

[PATCH 1/2] pwm: pwm-mediatek: Add support for MediaTek Helio X10 MT6795

[AngeloGioacchino Del Regno]

The MediaTek Helio X10 MT6795 SoC has 7 PWMs: add a compatible string
to use the right match data.
