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.
