Some Mediatek's SoC have an Accelerated Processing Unit. This adds support of the one available in the mt8183 (aswell some derivative SoC). This series depends on two other series: - Mediatek MT8183 scpsys support - arm64: dts: Add m4u and smi-larbs nodes for mt8183 Changes in v2: - Drop the workarounds needed to load bad firmwares - There are many name for the APU (most common one is VPU). Rename many functions and dts nodes to be more consistent. - Use the bulk clock API, and enable / disable clock at a better place - add few comments explaining how to start the APU - update the way to use pinctl for JTAG - fix some minors issues - fix device tree bindings Alexandre Bailon (4): dt bindings: remoteproc: Add bindings for MT8183 APU remoteproc: Add a remoteproc driver for the MT8183's APU remoteproc: mtk_vpu_rproc: Add support of JTAG ARM64: mt8183: Add support of APU to mt8183 .../bindings/remoteproc/mtk,apu.yaml | 107 +++++ arch/arm64/boot/dts/mediatek/mt8183.dtsi | 39 ++ drivers/remoteproc/Kconfig | 19 + drivers/remoteproc/Makefile | 1 + drivers/remoteproc/mtk_apu.c | 437 ++++++++++++++++++ 5 files changed, 603 insertions(+) create mode 100644 Documentation/devicetree/bindings/remoteproc/mtk,apu.yaml create mode 100644 drivers/remoteproc/mtk_apu.c -- 2.26.2
