| Subject | [PATCH v3 7/7] ARM: bcm2835: Add VC4 to the device tree. |
| Message-ID | <qhNoL-5IG-19@gated-at.bofh.it> |
VC4 is the GPU (display and 3D) present on the 2835.
Signed-off-by: Eric Anholt <eric@anholt.net>

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.
