The i.MX8M has two Hantro video decoders, called G1 and G2 which appear to be related to the video decoders used on the i.MX8MQ, but because of how the Mini handles the power domains, the VPU driver does not need to handle all the functions, so a new compatible flag is required. V3 is rebased from git://linuxtv.org/hverkuil/media_tree.git for-v5.17c This branch has support for VP9. I set cma=512M, but this may not be enough memory as some tests appeard to run out of memory V3 of this series has several changes: Update imx8m_vpu_hw to add missing 'reg' reference names for G2 and include references to VP9 Update device tree to remove IMX8MQ_VPU_RESET, remove some duplicate vpu clock parenting Fix missing reg-names from vpu_g2 node. Apply patch [1] to manage the power domains powering down.
