Subject: [RFC PATCH v2 0/3] ARM: dts: Support official Raspberry Pi 7inch touchscreen
Date:   Wed, 27 Apr 2022 14:52:40 -0400

Add a devicetree overlay to support the official Raspberry Pi 7inch touchscreen.

This also demuxes the i2c0 controller to support both pinctrls.

Changes in v2:
 * The device tree in now an overlay
 * The i2c demux patch is kept for now to have a working patch set. It has
   not been merged yet in [1].
 * The device tree overlay doesn't use fragments. It is working as is 
   but not enough literature was found to go one way or the other.
