From 1a1bf58aafd09b3cb148eead3d709e2d7974a1f3 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Wed, 15 Jul 2015 07:10:22 +0000 Subject: [PATCH] ASoC: rsnd: add workaround for SRC sync convert + DVC We couldn't use SRC sync convert mode together with DVC, but we can use workaround for it. This patch adds workaround and can use SRC sync convert + DVC Signed-off-by: Kuninori Morimoto Tested-by: Keita Kobayashi Signed-off-by: Mark Brown --- sound/soc/sh/rcar/src.c | 43 ++++++++++++++++++++++++++++++----------- 1 file changed, 32 insertions(+), 11 deletions(-) diff --git a/sound/soc/sh/rcar/src.c b/sound/soc/sh/rcar/src.c index 9e11f731a3a1..38d0aba7426e 100644 --- a/sound/soc/sh/rcar/src.c +++ b/sound/soc/sh/rcar/src.c @@ -616,6 +616,14 @@ static void rsnd_src_irq_ctrol_gen2(struct rsnd_mod *mod, int enable) int_val = 0; } + /* + * WORKAROUND + * + * ignore over flow error when rsnd_enable_sync_convert() + */ + if (rsnd_enable_sync_convert(src)) + sys_int_val = sys_int_val & 0xffff; + rsnd_mod_write(mod, SRC_INT_ENABLE0, int_val); rsnd_mod_bset(mod, SCU_SYS_INT_EN0, sys_int_mask, sys_int_val); rsnd_mod_bset(mod, SCU_SYS_INT_EN1, sys_int_mask, sys_int_val); @@ -631,11 +639,22 @@ static void rsnd_src_error_clear_gen2(struct rsnd_mod *mod) static bool rsnd_src_error_record_gen2(struct rsnd_mod *mod) { - u32 val = OUF_SRC(rsnd_mod_id(mod)); + struct rsnd_src *src = rsnd_mod_to_src(mod); + u32 val0, val1; bool ret = false; - if ((rsnd_mod_read(mod, SCU_SYS_STATUS0) & val) || - (rsnd_mod_read(mod, SCU_SYS_STATUS1) & val)) { + val0 = val1 = OUF_SRC(rsnd_mod_id(mod)); + + /* + * WORKAROUND + * + * ignore over flow error when rsnd_enable_sync_convert() + */ + if (rsnd_enable_sync_convert(src)) + val0 = val0 & 0xffff; + + if ((rsnd_mod_read(mod, SCU_SYS_STATUS0) & val0) || + (rsnd_mod_read(mod, SCU_SYS_STATUS1) & val1)) { struct rsnd_src *src = rsnd_mod_to_src(mod); src->err++; @@ -651,7 +670,16 @@ static bool rsnd_src_error_record_gen2(struct rsnd_mod *mod) static int _rsnd_src_start_gen2(struct rsnd_mod *mod, struct rsnd_dai_stream *io) { - u32 val = rsnd_io_to_mod_dvc(io) ? 0x01 : 0x11; + struct rsnd_src *src = rsnd_mod_to_src(mod); + u32 val; + + /* + * WORKAROUND + * + * Enable SRC output if you want to use sync convert together with DVC + */ + val = (rsnd_io_to_mod_dvc(io) && !rsnd_enable_sync_convert(src)) ? + 0x01 : 0x11; rsnd_mod_write(mod, SRC_CTRL, val); @@ -920,13 +948,6 @@ static int rsnd_src_pcm_new(struct rsnd_mod *mod, if (!rsnd_rdai_is_clk_master(rdai)) return 0; - /* - * We can't use SRC sync convert - * if it has DVC - */ - if (rsnd_io_to_mod_dvc(io)) - return 0; - /* * enable sync convert */ -- 2.39.2
