Add support for AR30 and BA30 pixel formats to the Mediatek DRM driver. Tested using "modetest -P" on an MT8195. Signed-off-by: Justin Green <greenjustin@xxxxxxxxxxxx> --- v2: * Rebase and resolve merge conflicts with the AFBC patch. v3: * Moved 10-bit support detection to mtk_disk_ovl.c v4: * Moved formats to mtk_disp_ovl.c and mtk_disp_rdma.c v5: * Minor style adjustments per checkpatch.pl drivers/gpu/drm/mediatek/mtk_disp_drv.h | 4 ++ drivers/gpu/drm/mediatek/mtk_disp_ovl.c | 75 +++++++++++++++++++++ drivers/gpu/drm/mediatek/mtk_disp_rdma.c | 27 ++++++++ drivers/gpu/drm/mediatek/mtk_drm_crtc.c | 4 +- drivers/gpu/drm/mediatek/mtk_drm_ddp_comp.c | 4 ++ drivers/gpu/drm/mediatek/mtk_drm_ddp_comp.h | 20 ++++++ drivers/gpu/drm/mediatek/mtk_drm_plane.c | 28 +++----- drivers/gpu/drm/mediatek/mtk_drm_plane.h | 3 +- 8 files changed, 146 insertions(+), 19 deletions(-) diff --git a/drivers/gpu/drm/mediatek/mtk_disp_drv.h b/drivers/gpu/drm/mediatek/mtk_disp_drv.h index 33e61a136bbc..6ad22ce75b81 100644 --- a/drivers/gpu/drm/mediatek/mtk_disp_drv.h +++ b/drivers/gpu/drm/mediatek/mtk_disp_drv.h @@ -96,6 +96,8 @@ void mtk_ovl_register_vblank_cb(struct device *dev, void mtk_ovl_unregister_vblank_cb(struct device *dev); void mtk_ovl_enable_vblank(struct device *dev); void mtk_ovl_disable_vblank(struct device *dev); +const u32 *mtk_ovl_get_formats(struct device *dev); +size_t mtk_ovl_get_num_formats(struct device *dev); void mtk_rdma_bypass_shadow(struct device *dev); int mtk_rdma_clk_enable(struct device *dev); @@ -122,4 +124,6 @@ void mtk_mdp_rdma_start(struct device *dev, struct cmdq_pkt *cmdq_pkt); void mtk_mdp_rdma_stop(struct device *dev, struct cmdq_pkt *cmdq_pkt); void mtk_mdp_rdma_config(struct device *dev, struct mtk_mdp_rdma_cfg *cfg, struct cmdq_pkt *cmdq_pkt); +const u32 *mtk_rdma_get_formats(struct device *dev); +size_t mtk_rdma_get_num_formats(struct device *dev); #endif diff --git a/drivers/gpu/drm/mediatek/mtk_disp_ovl.c b/drivers/gpu/drm/mediatek/mtk_disp_ovl.c index 84daeaffab6a..1db70a77560f 100644 --- a/drivers/gpu/drm/mediatek/mtk_disp_ovl.c +++ b/drivers/gpu/drm/mediatek/mtk_disp_ovl.c @@ -41,6 +41,7 @@ #define DISP_REG_OVL_RDMA_CTRL(n) (0x00c0 + 0x20 * (n)) #define DISP_REG_OVL_RDMA_GMC(n) (0x00c8 + 0x20 * (n)) #define DISP_REG_OVL_ADDR_MT2701 0x0040 +#define DISP_REG_OVL_CLRFMT_EXT 0x02D0 #define DISP_REG_OVL_ADDR_MT8173 0x0f40 #define DISP_REG_OVL_ADDR(ovl, n) ((ovl)->data->addr + 0x20 * (n)) #define DISP_REG_OVL_HDR_ADDR(ovl, n) ((ovl)->data->addr + 0x20 * (n) + 0x04) @@ -61,11 +62,45 @@ 0 : OVL_CON_CLRFMT_RGB) #define OVL_CON_CLRFMT_RGB888(ovl) ((ovl)->data->fmt_rgb565_is_0 ?
