Also, switch the users to make calls to the newly defined and generic s3c_i2sv2_get_clock Signed-off-by: Jassi Brar --- sound/soc/s3c24xx/jive_wm8750.c | 2 +- sound/soc/s3c24xx/s3c-i2s-v2.c | 12 ++++++++++++ sound/soc/s3c24xx/s3c-i2s-v2.h | 2 ++ sound/soc/s3c24xx/s3c2412-i2s.c | 13 ------------- sound/soc/s3c24xx/s3c2412-i2s.h | 2 -- sound/soc/s3c24xx/s3c64xx-i2s.c | 12 ------------ sound/soc/s3c24xx/s3c64xx-i2s.h | 2 -- 7 files changed, 15 insertions(+), 30 deletions(-) diff --git a/sound/soc/s3c24xx/jive_wm8750.c b/sound/soc/s3c24xx/jive_wm8750.c index 59dc2c6..304240d 100644 --- a/sound/soc/s3c24xx/jive_wm8750.c +++ b/sound/soc/s3c24xx/jive_wm8750.c @@ -70,7 +70,7 @@ static int jive_hw_params(struct snd_pcm_substream *substream, } s3c_i2sv2_iis_calc_rate(&div, NULL, params_rate(params), - s3c2412_get_iisclk()); + s3c_i2sv2_get_clock(cpu_dai)); /* set codec DAI configuration */ ret = snd_soc_dai_set_fmt(codec_dai, SND_SOC_DAIFMT_I2S | diff --git a/sound/soc/s3c24xx/s3c-i2s-v2.c b/sound/soc/s3c24xx/s3c-i2s-v2.c index 1b29b4b..ecb3054 100644 --- a/sound/soc/s3c24xx/s3c-i2s-v2.c +++ b/sound/soc/s3c24xx/s3c-i2s-v2.c @@ -499,6 +499,18 @@ static snd_pcm_sframes_t s3c2412_i2s_delay(struct snd_pcm_substream *substream, return delay; } +struct clk *s3c_i2sv2_get_clock(struct snd_soc_dai *cpu_dai) +{ + struct s3c_i2sv2_info *i2s = to_info(cpu_dai); + u32 iismod = readl(i2s->regs + S3C2412_IISMOD); + + if (iismod & S3C2412_IISMOD_IMS_SYSMUX) + return i2s->iis_cclk; + else + return i2s->iis_pclk; +} +EXPORT_SYMBOL_GPL(s3c_i2sv2_get_clock); + /* default table of all avaialable root fs divisors */ static unsigned int iis_fs_tab[] = { 256, 512, 384, 768 }; diff --git a/sound/soc/s3c24xx/s3c-i2s-v2.h b/sound/soc/s3c24xx/s3c-i2s-v2.h index ea56467..39a6db6 100644 --- a/sound/soc/s3c24xx/s3c-i2s-v2.h +++ b/sound/soc/s3c24xx/s3c-i2s-v2.h @@ -60,6 +60,8 @@ struct s3c_i2sv2_info { u32 suspend_iispsr; }; +extern struct clk *s3c_i2sv2_get_clock(struct snd_soc_dai *cpu_dai); + struct s3c_i2sv2_rate_calc { unsigned int clk_div; /* for prescaler */ unsigned int fs_div; /* for root frame clock */ diff --git a/sound/soc/s3c24xx/s3c2412-i2s.c b/sound/soc/s3c24xx/s3c2412-i2s.c index 4996843..fe90867 100644 --- a/sound/soc/s3c24xx/s3c2412-i2s.c +++ b/sound/soc/s3c24xx/s3c2412-i2s.c @@ -91,19 +91,6 @@ static int s3c2412_i2s_set_sysclk(struct snd_soc_dai *cpu_dai, return 0; } - -struct clk *s3c2412_get_iisclk(void) -{ - struct s3c_i2sv2_info *i2s = &s3c2412_i2s; - u32 iismod = readl(i2s->regs + S3C2412_IISMOD); - - if (iismod & S3C2412_IISMOD_IMS_SYSMUX) - return i2s->iis_cclk; - else - return i2s->iis_pclk; -} -EXPORT_SYMBOL_GPL(s3c2412_get_iisclk); - static inline struct s3c_i2sv2_info *to_info(struct snd_soc_dai *cpu_dai) { return cpu_dai->private_data; diff --git a/sound/soc/s3c24xx/s3c2412-i2s.h b/sound/soc/s3c24xx/s3c2412-i2s.h index 60cac00..0b5686b 100644 --- a/sound/soc/s3c24xx/s3c2412-i2s.h +++ b/sound/soc/s3c24xx/s3c2412-i2s.h @@ -24,8 +24,6 @@ #define S3C2412_CLKSRC_PCLK S3C_I2SV2_CLKSRC_PCLK #define S3C2412_CLKSRC_I2SCLK S3C_I2SV2_CLKSRC_AUDIOBUS -extern struct clk *s3c2412_get_iisclk(void); - extern struct snd_soc_dai s3c2412_i2s_dai; #endif /* __SND_SOC_S3C24XX_S3C2412_I2S_H */ diff --git a/sound/soc/s3c24xx/s3c64xx-i2s.c b/sound/soc/s3c24xx/s3c64xx-i2s.c index 9bcc99d..9343349 100644 --- a/sound/soc/s3c24xx/s3c64xx-i2s.c +++ b/sound/soc/s3c24xx/s3c64xx-i2s.c @@ -91,18 +91,6 @@ static int s3c64xx_i2s_set_sysclk(struct snd_soc_dai *cpu_dai, return 0; } -struct clk *s3c64xx_i2s_get_clock(struct snd_soc_dai *dai) -{ - struct s3c_i2sv2_info *i2s = to_info(dai); - u32 iismod = readl(i2s->regs + S3C2412_IISMOD); - - if (iismod & S3C64XX_IISMOD_IMS_SYSMUX) - return i2s->iis_cclk; - else - return i2s->iis_pclk; -} -EXPORT_SYMBOL_GPL(s3c64xx_i2s_get_clock); - static int s3c64xx_i2s_probe(struct platform_device *pdev, struct snd_soc_dai *dai) { diff --git a/sound/soc/s3c24xx/s3c64xx-i2s.h b/sound/soc/s3c24xx/s3c64xx-i2s.h index 53d2a0a..f27ed50 100644 --- a/sound/soc/s3c24xx/s3c64xx-i2s.h +++ b/sound/soc/s3c24xx/s3c64xx-i2s.h @@ -38,6 +38,4 @@ struct clk; extern struct snd_soc_dai s3c64xx_i2s_dai[]; -extern struct clk *s3c64xx_i2s_get_clock(struct snd_soc_dai *dai); - #endif /* __SND_SOC_S3C24XX_S3C64XX_I2S_H */ -- 1.6.2.5
