However this register space is already assigned to a different node on both MT8173 and MT8183: a clock-controller node called 'vdecsys' which is also a syscon. In order to resolve the overlapping address ranges, remove the VDEC_SYS register space from the video decoder, and add a new property to hold the phandle to the syscon, so that iospace can still be handled. Also add reg-names to be able to tell that this new register schema is used, so the driver can keep backward compatibility. Signed-off-by: Nícolas F. R. A.

To achieve that, rely on a vdecsys syscon to be passed through the DT, and use it to directly read the VDEC_HW_ACTIVE bit during IRQ handling to check whether the HW is active. Also update the VP8 stateful decoder to use the syscon, if present, for writes to VDEC_SYS. The old behavior is still present when reg-names aren't supplied, as to keep backward compatibility. Signed-off-by: Nícolas F. R. A. Prado --- Changes in v4: - Added new helper and updated VP8 stateful decoder to use it, so the syscon can also be used by mt8173 - Made handling cleaner - Reworded commit Changes in v3: - Switched handling of VDEC_HW_ACTIVE to use a syscon instead of the 'active' clock - Reworded commit - Removed changes to subdev part of driver, since they aren't used by MT8183 .../mediatek/vcodec/mtk_vcodec_dec_drv.c | 76 ++++++++++++++++--- .../platform/mediatek/vcodec/mtk_vcodec_drv.h | 1 + .../mediatek/vcodec/mtk_vcodec_util.c | 15 ++++ .../mediatek/vcodec/mtk_vcodec_util.h | 2 + .../mediatek/vcodec/vdec/vdec_vp8_if.c | 10 +-- 5 files changed, 86 insertions(+), 18 deletions(-) diff --git a/drivers/media/platform/mediatek/vcodec/mtk_vcodec_dec_drv.c b/drivers/media/platform/mediatek/vcodec/mtk_vcodec_dec_drv.c index 83780d29a9cf..d83c2eb6f118 100644 --- a/drivers/media/platform/mediatek/vcodec/mtk_vcodec_dec_drv.c +++ b/drivers/media/platform/mediatek/vcodec/mtk_vcodec_dec_drv.c @@ -8,10 +8,12 @@ #include #include #include +#include #include #include #include #include +#include #include #include #include @@ -38,22 +40,30 @@ static int mtk_vcodec_get_hw_count(struct mtk_vcodec_dev *dev) } } +static bool mtk_vcodec_is_hw_active(struct mtk_vcodec_dev *dev) +{ + u32 cg_status;
