    Subject[PATCH v5 3/3] ARM: dts: qcom: Add support for Samsung Galaxy Tab 4 10.1 (SM-T530)
    Date
    Add a device tree for the Samsung Galaxy Tab 4 10.1 (SM-T530) wifi tablet
    based on the apq8026 platform.

    Currently supported are accelerometer sensor, hall sensor,
    internal storage, physical buttons (power & volume), screen
    (based on simple-framebuffer set up by the bootloader), sdcard,
    touchscreen and USB.

    - Move usb-switch node to blsp_i2c4

    Changes in v3:
    - Fix sdhc_2 bus width
    - Reorder includes

    Changes in v2:
    - Change codename to matisse-wifi
