From ab6f6d85210c4d0265cf48e9958c04e08595055a Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Mon, 5 Nov 2012 18:30:38 -0800 Subject: ASoC: fsi: add master clock control functions Current FSI driver required set_rate() platform callback function to set audio clock if it was master mode, because it seemed that CPG/FSI-DIV clocks calculation depend on platform/board/cpu. But it was calculable regardless of platform. This patch supports audio clock calculation method, but the sampling rate under 32kHz is not supported at this point. Old type set_rate() is still supported now, but it will be deleted on next version Signed-off-by: Kuninori Morimoto Signed-off-by: Mark Brown --- include/sound/sh_fsi.h | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'include/sound/sh_fsi.h') diff --git a/include/sound/sh_fsi.h b/include/sound/sh_fsi.h index 906010344dd7..27ee1dcc3e2e 100644 --- a/include/sound/sh_fsi.h +++ b/include/sound/sh_fsi.h @@ -26,6 +26,7 @@ * A: inversion * B: format mode * C: chip specific + * D: clock selecter if master mode */ /* A: clock inversion */ @@ -44,6 +45,11 @@ #define SH_FSI_OPTION_MASK 0x00000F00 #define SH_FSI_ENABLE_STREAM_MODE (1 << 8) /* for 16bit data */ +/* D: clock selecter if master mode */ +#define SH_FSI_CLK_MASK 0x0000F000 +#define SH_FSI_CLK_EXTERNAL (1 << 12) +#define SH_FSI_CLK_CPG (2 << 12) /* FSIxCK + FSI-DIV */ + /* * set_rate return value * -- cgit v1.2.3
