The ARM Mali Midgard GPU kernel driver is only available out-of-tree and is not going to be merged in its current form. However, it would be useful to have its device tree bindings merged. In particular, this would enable distributions to create working driver packages (dkms...) without having to patch the kernel. The bindings for the earlier Mali Utgard GPU family have already been merged, so this is essentially the same scenario but for newer GPUs (Mali-T604 ~ Mali-T880). This series of patches first imports the bindings from the latest driver release with some clean-up then adds a gpu node for the rk3288 SoC. This was successfully tested on Radxa Rock2 Square, Firefly, Veyron Minnie and Jerry boards board using Mali kernel driver r16p0 and r12p0 user-space binary. Changes since v1: - enabled gpu on rk3288-veyron boards Changes since v2: - removed "clk-names" property and "clk_mali" name - converted values of "interrupt-names" property to lower-case: "job", "mmu" and "gpu" - replaced dt compatible strings with list of all Midgard GPU variants and optional vendors - cleaned up gpu node example Enric Balletbo i Serra (1): ARM: dts: rockchip: enable ARM Mali GPU on rk3288-veyron Guillaume Tucker (4): dt-bindings: gpu: add bindings for the ARM Mali Midgard GPU ARM: dts: rockchip: add ARM Mali GPU node for rk3288 ARM: dts: rockchip: enable ARM Mali GPU on rk3288-rock2-som ARM: dts: rockchip: enable ARM Mali GPU on rk3288-firefly .../devicetree/bindings/gpu/arm,mali-midgard.txt | 57 ++++++++++++++++++++++ arch/arm/boot/dts/rk3288-firefly.dtsi | 5 ++ arch/arm/boot/dts/rk3288-rock2-som.dtsi | 5 ++ arch/arm/boot/dts/rk3288-veyron.dtsi | 5 ++ arch/arm/boot/dts/rk3288.dtsi | 22 +++++++++ 5 files changed, 94 insertions(+) create mode 100644 Documentation/devicetree/bindings/gpu/arm,mali-midgard.txt -- 2.11.0 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
