[PATCH v2 2/7] arm64: dts: freescale: add initial tree for TQMa8MQML with i.MX8MM

From: Alexander Stein
Date: Fri Nov 05 2021 - 11:30:48 EST

This adds support for TQMa8MQML module on MBa8Mx board.

Signed-off-by: Alexander Stein <alexander.stein@xxxxxxxxxxxxxxx>
---
Changes in v2:
* Fixed ordering in Makefile
* Renamed codec -> audio_codec
* Add USB interfaces & USB extcon & pinctrl nodes
* Fixed pinctrl node names
* Removed empty chosen node
* Removed regulator-always-on on non-switchable regulators
* Changed spi-tx-bus-width for spi-nor flash similar to commit 04aa946d57b2
("arm64: dts: imx8: change the spi-nor tx")
* Enabled gpu_2d and gpu_3d nodes
* Removed Ethernet PHY IRQ support (was unreliable)
