From 41135d2ce60509e53306e5b76afab98ddc15951b Mon Sep 17 00:00:00 2001

Subject: [PATCH 26/36] ARM: bcm2835: Add VC4 to the device tree.

VC4 is the GPU (display and 3D) present on the 283x.

v2: Sort by register address, mark HDMI as disabled by default in the
    SoC file and enable it from -rpi.
v3: Add references to the pixel/HSM clocks for HDMI.  Rename
    compatibility strings and clean up node names.
v4: Fix comment marking pv0's interrupt as pwa2 instead of pwa0.
    Rename hpd-gpio to hpd-gpios.
v5: Rebase on bcm283x.dtsi change, add v3d.
v6: Make HDMI reference the power domain.
v7: Fix the HDMI HPD gpios active value and HDMI enable for each RPI
    board.  Change V3D compatible string to 2835.

Subject: [PATCH 28/36] ARM: bcm2835: Add devicetree for the Raspberry Pi 3.

For now this doesn't support the new hardware present on the Pi 3 (BT,
wifi, GPIO expander).  Since the GPIO expander isn't supported, we
also don't have the LEDs like the other board files do.
