There is initialization code in VPU code to pull some clocks, resets and other features which has been integrated into the vpu-blk-ctrl for the i.MX8M Mini and a similar method can be used to make the VPU codec's operate as stand-alone cores without having to know the details of each other or the quirks unique to the i.MX8MQ, so the remaining code can be left more generic. This series was started by Lucas Stach, and picked up by me so some patches have his s-o-b and mine where I might have changed a few minor items. It's in an RFC state because the G2 VP9 operations appear to hang, but the parent code from which I started doesn't appear to show VP9 support, and it looks like it should. since the g-streamer and media trees are in a constant state of change, this series is based on git://linuxtv.org/hverkuil/media_tree.git for-v5.17e Adam Ford (2): media: hantro: split i.MX8MQ G1 and G2 code arm64: dts: imx8mq: Split i.MX8MQ G1 and G2 with vpu-blk-ctrl Lucas Stach (3): dt-bindings: power: imx8mq: add defines for VPU blk-ctrl domains dt-bindings: soc: add binding for i.MX8MQ VPU blk-ctrl soc: imx: imx8m-blk-ctrl: add i.MX8MQ VPU blk-ctrl .../soc/imx/fsl,imx8mq-vpu-blk-ctrl.yaml | 71 +++++++++++ arch/arm64/boot/dts/freescale/imx8mq.dtsi | 69 ++++++---- drivers/soc/imx/imx8m-blk-ctrl.c | 67 ++++++++++ drivers/staging/media/hantro/hantro_drv.c | 4 +- drivers/staging/media/hantro/hantro_hw.h | 2 +- drivers/staging/media/hantro/imx8m_vpu_hw.c | 119 +++--------------- include/dt-bindings/power/imx8mq-power.h | 3 + 7 files changed, 205 insertions(+), 130 deletions(-) create mode 100644 Documentation/devicetree/bindings/soc/imx/fsl,imx8mq-vpu-blk-ctrl.yaml
