From c3e5203bed1999df716e3c7119f6749523eb952f Mon Sep 17 00:00:00 2001 From: Cliff Cai Date: Mon, 27 Oct 2008 17:09:25 +0800 Subject: ALSA: ASoC: Blackfin: update SPORT0 port selector (v2) - Setting the TFS pin selector for SPORT 0 based on whether the selected port id F or G. If the port is F then no conflict should exist for the TFS. When Port G is selected and EMAC then there is a conflict between the PHY interrupt line and TFS. Current settings prevent the conflict by ignoring the TFS pin when Port G is selected. This allows both ssm2602 using Port G and EMAC concurrently. - some code cleanup Signed-off-by: Cliff Cai Signed-off-by: Bryan Wu Acked-by: Mark Brown Signed-off-by: Takashi Iwai --- sound/soc/blackfin/bf5xx-i2s.c | 34 ++++++++++++++++++++++------------ 1 file changed, 22 insertions(+), 12 deletions(-) (limited to 'sound') diff --git a/sound/soc/blackfin/bf5xx-i2s.c b/sound/soc/blackfin/bf5xx-i2s.c index 827587f0818..e020c160ee4 100644 --- a/sound/soc/blackfin/bf5xx-i2s.c +++ b/sound/soc/blackfin/bf5xx-i2s.c @@ -70,12 +70,24 @@ static struct sport_param sport_params[2] = { } }; -static u16 sport_req[][7] = { - { P_SPORT0_DTPRI, P_SPORT0_TSCLK, P_SPORT0_RFS, - P_SPORT0_DRPRI, P_SPORT0_RSCLK, 0}, - { P_SPORT1_DTPRI, P_SPORT1_TSCLK, P_SPORT1_RFS, - P_SPORT1_DRPRI, P_SPORT1_RSCLK, 0}, -}; +/* + * Setting the TFS pin selector for SPORT 0 based on whether the selected + * port id F or G.
