Subject: [PATCH 3/3] ARM: bcm2835: Add VC4 to the device tree.
Date: Fri, 4 Mar 2016 12:32:08 -0800 [thread overview]
Message-ID: <1457123528-13482-4-git-send-email-eric@anholt.net> (raw)
In-Reply-To: <1457123528-13482-1-git-send-email-eric@anholt.net>
VC4 is the GPU (display and 3D) present on the 283x.
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.
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.
