[PATCH v5 10/10] arm64: dts: freescale: add apalis imx8 aka quadmax carrier board support

From: Marcel Ziswiler
Date: Thu Jan 26 2023 - 06:10:27 EST

From: Marcel Ziswiler <marcel.ziswiler@xxxxxxxxxxx>

The previous patch added the device tree to support Toradex Apalis
iMX8 [1] aka QuadMax a computer on module which can be used on
different carrier boards which this patch introduces.

The module consists of an NXP i.MX 8 family SoC (either i.MX 8QuadMax or
8QuadPlus), two PF8100 PMICs, a KSZ9131 Gigabit Ethernet PHY, 2, 4 or 8
GB of LPDDR4 RAM, an eMMC, an SGTL5000 analogue audio codec, an USB3503A
USB HSIC hub, an optional I2C EEPROM plus an optional Bluetooth/Wi-Fi
module.

Anything that is not self-contained on the module is disabled by
default.

The carrier board device trees contained in this patch include the
module's device tree and enable the supported peripherals of the
carrier board.

Some level of display functionality just landed upstream but requires
further integration/testing on our side. Therefore, currently only
basic console UART, eMMC and Ethernet functionality work fine.

As there is no i.MX 8QuadPlus device tree upstream those have been
dropped. However, apart from an error message during boot about it
failing to bring up the second Cortex-A72 core this boots fine on
QuadPlus' as well.

Changes in v5:
- Remove LVDS PWM support waiting for Liu's patches to land first.
- Remove bkl1_pwm functionality depending on the above.
- Squashing all Apalis iMX8 specific device tree patches. As outlined by
Krzysztof reviewers may simply use b4 diff.

Changes in v4:
- Shorten subject.

Changes in v3:
- Only use V1.1 compatible for V1.1 module dtsi.
- Split patch into separate module and carrier boards parts as suggested
by Shawn.
- Put reg after compatible as requested by Shawn.
- Move atmel_mxt_ts and rtc_i2c into module dtsi to save such
duplications as suggested by Shawn.
- Change iomuxc pinctrl indent style as suggested by Shawn.
- Change led node names to the preferred first form as suggested by
Shawn. While at it also add color (yikes), default-state and function
properties and remove the deprecated label property.
- Put enable-active-high properties after the gpio ones as suggested by
Shawn. Thanks!
- Remove adc node's vref-supply and accompanying reg_vref_1v8 regulator
node.
- Rename gpio-hogs adherring to dt schema naming convention.
