    arm64: dts: freescale: add apalis imx8 aka quadmax carrier board support · c083131c
    Marcel Ziswiler authored
    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.
