Subject: [RFC PATCH v2 0/3] ARM: dts: Support official Raspberry Pi 7inch touchscreen
Date: Mon, 21 Feb 2022 09:01:14 -0500 [thread overview]
Message-ID: <20220221140117.90284-1-detlev.casanova@collabora.com> (raw)
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.
