    ARM: tegra: add device tree for SHIELD · e9d68f90
    Alexandre Courbot authored
    NVIDIA SHIELD is a portable Android console containing a Tegra 4 SoC with
    2GB RAM and a 720p panel.
    
    The following hardware is enabled by this device tree: UART, eMMC, USB
    (needs external power), PMIC, backlight, joystick, SD card, GPIO keys.
    
    DSI panel, HDMI output, charger, self-powered USB, audio, wifi bluetooth
    are not supported yet but might be by future patches (likely in that
    order).
    
    Touch panel and sensors will probably never be supported.
    
    Initrd addresses are hardcoded to match the static values used by the
    bootloader, since it won't add them for us. All the same, a kernel
    command-line is provided to replace the one passed by the
    bootloader which is filled with garbage.
    
    NVIDIA SHIELD is typically booted with an appended DTB to avoid
    modifications made by the bootloader.
