Due to the difference of HW, different dividers need to be set. Signed-off-by: Shuijing Li <shuijing.li@xxxxxxxxxxxx> Signed-off-by: Jitao Shi <jitao.shi@xxxxxxxxxxxx> --- Changes in v3: Separate these two things into two different patches. per suggestion from the previous thread: https://lore.kernel.org/lkml/e2ad22bcba31797f38a12a488d4246a01bf0cb2e.camel@xxxxxxxxxxxx/ Changes in v2: - change the variables' name to be more descriptive - add a comment that describes the function of mtk_dp_audio_sample_arrange - reduce indentation by doing the inverse check - add a definition of some bits - add support for mediatek, mt8188-edp-tx per suggestion from the previous thread: https://lore.kernel.org/lkml/ac0fcec9-a2fe-06cc-c727-189ef7babe9c@xxxxxxxxxxxxx/ --- drivers/gpu/drm/mediatek/mtk_dp.c | 7 ++++++- drivers/gpu/drm/mediatek/mtk_dp_reg.h | 1 + 2 files changed, 7 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/mediatek/mtk_dp.c b/drivers/gpu/drm/mediatek/mtk_dp.c index d8cda83d6fef..8e1a13ab2ba2 100644 --- a/drivers/gpu/drm/mediatek/mtk_dp.c +++ b/drivers/gpu/drm/mediatek/mtk_dp.c @@ -140,6 +140,7 @@ struct mtk_dp_data { const struct mtk_dp_efuse_fmt *efuse_fmt; bool audio_supported; bool audio_pkt_in_hblank_area; + u16 audio_m_div2_bit; }; static const struct mtk_dp_efuse_fmt mt8195_edp_efuse_fmt[MTK_DP_CAL_MAX] = { @@ -648,7 +649,7 @@ static void mtk_dp_audio_sdp_asp_set_channels(struct mtk_dp *mtk_dp, static void mtk_dp_audio_set_divider(struct mtk_dp *mtk_dp) { mtk_dp_update_bits(mtk_dp, MTK_DP_ENC0_P0_30BC, - AUDIO_M_CODE_MULT_DIV_SEL_DP_ENC0_P0_DIV_2, + mtk_dp->data->audio_m_div2_bit, AUDIO_M_CODE_MULT_DIV_SEL_DP_ENC0_P0_MASK); } @@ -2636,6 +2637,7 @@ static const struct mtk_dp_data mt8188_edp_data = { .efuse_fmt = mt8195_edp_efuse_fmt, .audio_supported = false, .audio_pkt_in_hblank_area = false, + .audio_m_div2_bit = MT8188_AUDIO_M_CODE_MULT_DIV_SEL_DP_ENC0_P0_DIV_2, }; static const struct mtk_dp_data mt8188_dp_data = { @@ -2644,6 +2646,7 @@ static const struct mtk_dp_data mt8188_dp_data = { .efuse_fmt = mt8195_dp_efuse_fmt, .audio_supported = true, .audio_pkt_in_hblank_area = true, + .audio_m_div2_bit = MT8188_AUDIO_M_CODE_MULT_DIV_SEL_DP_ENC0_P0_DIV_2, }; static const struct mtk_dp_data mt8195_edp_data = { @@ -2652,6 +2655,7 @@ static const struct mtk_dp_data mt8195_edp_data = { .efuse_fmt = mt8195_edp_efuse_fmt, .audio_supported = false, .audio_pkt_in_hblank_area = false, + .audio_m_div2_bit = AUDIO_M_CODE_MULT_DIV_SEL_DP_ENC0_P0_DIV_2, }; static const struct mtk_dp_data mt8195_dp_data = { @@ -2660,6 +2664,7 @@ static const struct mtk_dp_data mt8195_dp_data = { .efuse_fmt = mt8195_dp_efuse_fmt, .audio_supported = true, .audio_pkt_in_hblank_area = false, + .audio_m_div2_bit = AUDIO_M_CODE_MULT_DIV_SEL_DP_ENC0_P0_DIV_2, }; static const struct of_device_id mtk_dp_of_match[] = { diff --git a/drivers/gpu/drm/mediatek/mtk_dp_reg.h b/drivers/gpu/drm/mediatek/mtk_dp_reg.h index f38d6ff12afe..6d7f0405867e 100644 --- a/drivers/gpu/drm/mediatek/mtk_dp_reg.h +++ b/drivers/gpu/drm/mediatek/mtk_dp_reg.h @@ -162,6 +162,7 @@ #define AUDIO_M_CODE_MULT_DIV_SEL_DP_ENC0_P0_MUL_2 (1 << 8) #define AUDIO_M_CODE_MULT_DIV_SEL_DP_ENC0_P0_MUL_4 (2 << 8) #define AUDIO_M_CODE_MULT_DIV_SEL_DP_ENC0_P0_MUL_8 (3 << 8) +#define MT8188_AUDIO_M_CODE_MULT_DIV_SEL_DP_ENC0_P0_DIV_2 (4 << 8) #define AUDIO_M_CODE_MULT_DIV_SEL_DP_ENC0_P0_DIV_2 (5 << 8) #define AUDIO_M_CODE_MULT_DIV_SEL_DP_ENC0_P0_DIV_4 (6 << 8) #define AUDIO_M_CODE_MULT_DIV_SEL_DP_ENC0_P0_DIV_8 (7 << 8) -- 2.40.1
