intf_audio_select() callback function use to configure HDMI_DP_CORE_SELECT to decide audio output routes to HDMI or DP interface. HDMI is obsoleted at newer chipset. To keep supporting legacy hdmi application, intf_audio_select call back function have to be populated base on hardware chip capability where legacy chipsets have has_audio_select flag set to true.
Changes in V2: -- remove has_audio_select flag -- add BIT(DPU_MDP_AUDIO_SELECT) into dpu_mdp_cfg Signed-off-by: Kuogee Hsieh <[email protected]> --- drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.c | 2 +- drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.h | 1 + drivers/gpu/drm/msm/disp/dpu1/dpu_hw_top.c | 4 +++- 3 files changed, 5 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.c b/drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.c index 272b14b..9c2df26 100644 --- a/drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.c +++ b/drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.c @@ -265,7 +265,7 @@ static const struct dpu_mdp_cfg sdm845_mdp[] = { { .name = "top_0", .id = MDP_TOP, .base = 0x0, .len = 0x45C, - .features = 0, + .features = BIT(DPU_MDP_AUDIO_SELECT), .highest_bank_bit = 0x2, .clk_ctrls[DPU_CLK_CTRL_VIG0] = { .reg_off = 0x2AC, .bit_off = 0}, diff --git a/drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.h b/drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.h index e5a96d6..fb7b5b5 100644 --- a/drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.h +++ b/drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.h @@ -87,6 +87,7 @@ enum { DPU_MDP_BWC, DPU_MDP_UBWC_1_0, DPU_MDP_UBWC_1_5, + DPU_MDP_AUDIO_SELECT, DPU_MDP_MAX }; diff --git a/drivers/gpu/drm/msm/disp/dpu1/dpu_hw_top.c b/drivers/gpu/drm/msm/disp/dpu1/dpu_hw_top.c index 282e3c6..ab3ef16 100644 --- a/drivers/gpu/drm/msm/disp/dpu1/dpu_hw_top.c +++ b/drivers/gpu/drm/msm/disp/dpu1/dpu_hw_top.c @@ -268,7 +268,9 @@ static void _setup_mdp_ops(struct dpu_hw_mdp_ops *ops, ops->get_danger_status = dpu_hw_get_danger_status; ops->setup_vsync_source = dpu_hw_setup_vsync_source; ops->get_safe_status = dpu_hw_get_safe_status; - ops->intf_audio_select = dpu_hw_intf_audio_select; + + if (cap & BIT(DPU_MDP_AUDIO_SELECT)) + ops->intf_audio_select = dpu_hw_intf_audio_select; } static const struct dpu_mdp_cfg *_top_offset(enum dpu_mdp mdp, -- The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum, a Linux Foundation Collaborative Project
