Due to the difference of HW, different dividers need to be set. Signed-off-by: Shuijing Li <shuijing.li@xxxxxxxxxxxx> --- Changes in v4: list all configuration for MT8188 and MT8195. per suggestion from the previous thread: https://lore.kernel.org/all/a9d1b9b7ef4780f51574d0bbbe28f6dd109a6ab8.camel@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 | 6 +++++- drivers/gpu/drm/mediatek/mtk_dp_reg.h | 18 ++++++++++++------ 2 files changed, 17 insertions(+), 7 deletions(-) diff --git a/drivers/gpu/drm/mediatek/mtk_dp.c b/drivers/gpu/drm/mediatek/mtk_dp.c index be557b6f5854..fb110374ad1f 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); } @@ -2623,6 +2624,7 @@ 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 = { @@ -2630,6 +2632,7 @@ static const struct mtk_dp_data mt8195_edp_data = { .smc_cmd = MTK_DP_SIP_ATF_EDP_VIDEO_UNMUTE, .efuse_fmt = mt8195_edp_efuse_fmt, .audio_supported = false, + .audio_m_div2_bit = MT8195_AUDIO_M_CODE_MULT_DIV_SEL_DP_ENC0_P0_DIV_2, }; static const struct mtk_dp_data mt8195_dp_data = { @@ -2637,6 +2640,7 @@ static const struct mtk_dp_data mt8195_dp_data = { .smc_cmd = MTK_DP_SIP_ATF_VIDEO_UNMUTE, .efuse_fmt = mt8195_dp_efuse_fmt, .audio_supported = true, + .audio_m_div2_bit = MT8195_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..709b79480693 100644 --- a/drivers/gpu/drm/mediatek/mtk_dp_reg.h +++ b/drivers/gpu/drm/mediatek/mtk_dp_reg.h @@ -159,12 +159,18 @@ #define MTK_DP_ENC0_P0_30BC 0x30bc #define ISRC_CONT_DP_ENC0_P0 BIT(0) #define AUDIO_M_CODE_MULT_DIV_SEL_DP_ENC0_P0_MASK GENMASK(10, 8) -#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 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) +#define MT8195_AUDIO_M_CODE_MULT_DIV_SEL_DP_ENC0_P0_MUL_2 (1 << 8) +#define MT8195_AUDIO_M_CODE_MULT_DIV_SEL_DP_ENC0_P0_MUL_4 (2 << 8) +#define MT8195_AUDIO_M_CODE_MULT_DIV_SEL_DP_ENC0_P0_MUL_8 (3 << 8) +#define MT8195_AUDIO_M_CODE_MULT_DIV_SEL_DP_ENC0_P0_DIV_2 (5 << 8) +#define MT8195_AUDIO_M_CODE_MULT_DIV_SEL_DP_ENC0_P0_DIV_4 (6 << 8) +#define MT8195_AUDIO_M_CODE_MULT_DIV_SEL_DP_ENC0_P0_DIV_8 (7 << 8) +#define MT8188_AUDIO_M_CODE_MULT_DIV_SEL_DP_ENC0_P0_MUL_2 (1 << 8) +#define MT8188_AUDIO_M_CODE_MULT_DIV_SEL_DP_ENC0_P0_MUL_4 (2 << 8) +#define MT8188_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 MT8188_AUDIO_M_CODE_MULT_DIV_SEL_DP_ENC0_P0_DIV_4 (5 << 8) +#define MT8188_AUDIO_M_CODE_MULT_DIV_SEL_DP_ENC0_P0_DIV_8 (7 << 8) #define MTK_DP_ENC0_P0_30D8 0x30d8 #define MTK_DP_ENC0_P0_312C 0x312c #define ASP_HB2_DP_ENC0_P0_MASK GENMASK(7, 0) -- 2.40.1
