Used on various phones. Minimal basic support.

Includes device-tree with possibility to enable touchscreen on Pixel 3.

Sending as RFC, as this is first, seemingly clean version which works.

What is missing:
 - firmware loading
 - switching between AP and SLPI mode (to wake up phone by touch)
 - anything above basic touch

First, I said it's RFC, but I didn't marked the series such as, sorry bout that.

Second, already found typo in binding: s/switch-gpio/switch-gpios/ .

At last, the series, until merged can be found at:
