Subject: [PATCH v2 04/14] ARM: dts: imx6ull-colibri: add touchscreen device nodes
Date: Mon, 25 Apr 2022 18:23:46 +0200 [thread overview]
Message-ID: <20220425162356.176665-5-marcel@ziswiler.com> (raw)
In-Reply-To: <20220425162356.176665-1-marcel@ziswiler.com>
From: Denys Drozdov <denys.drozdov@toradex.com>
Move all Atmel nodes from the board-level into the main module-level
device tree and prepare the device trees for use with Atmel MXT device
tree overlays. Also, add required pinmux groups.
The common scheme for pin groups in touch screen overlays is as follows:
- pinctrl_atmel_conn - SODIMM 106/107 pins for INT/RST signals (default)
- pinctrl_atmel_adap - SODIMM 28/30 pins for INT/RST signals.

Changes in v2:
- Fixed pinctrl node names as suggested by Shawn.
