From 41135d2ce60509e53306e5b76afab98ddc15951b Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Mon, 2 Mar 2015 14:36:16 -0800 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.
