Modified logic to invoke sequence for two i2s controller instances. This also fixes warnings reported by kernel robot: "warning: variable 'frmt_val' set but not used" "warning: variable 'reg_val' set but not used" Reported-by: kernel test robot Signed-off-by: Vijendar Mukunda Link: https://lore.kernel.org/r/20220225193054.24916-1-Vijendar.Mukunda@amd.com Signed-off-by: Mark Brown Signed-off-by: Sasha Levin --- sound/soc/amd/vangogh/acp5x-pcm-dma.c | 66 +++++++++++++-------------- 1 file changed, 33 insertions(+), 33 deletions(-) diff --git a/sound/soc/amd/vangogh/acp5x-pcm-dma.c b/sound/soc/amd/vangogh/acp5x-pcm-dma.c index 6abcc2133a2c..bfca4cf423cf 100644 --- a/sound/soc/amd/vangogh/acp5x-pcm-dma.c +++ b/sound/soc/amd/vangogh/acp5x-pcm-dma.c @@ -426,51 +426,51 @@ static int acp5x_audio_remove(struct platform_device *pdev) static int __maybe_unused acp5x_pcm_resume(struct device *dev) { struct i2s_dev_data *adata; - u32 val, reg_val, frmt_val; + struct i2s_stream_instance *rtd; + u32 val; - reg_val = 0; - frmt_val = 0; adata = dev_get_drvdata(dev); if (adata->play_stream && adata->play_stream->runtime) { - struct i2s_stream_instance *rtd = - adata->play_stream->runtime->private_data; + rtd = adata->play_stream->runtime->private_data; config_acp5x_dma(rtd, SNDRV_PCM_STREAM_PLAYBACK); - switch (rtd->i2s_instance) { - case I2S_HS_INSTANCE: - reg_val = ACP_HSTDM_ITER; - frmt_val = ACP_HSTDM_TXFRMT; - break; - case I2S_SP_INSTANCE: - default: - reg_val = ACP_I2STDM_ITER; - frmt_val = ACP_I2STDM_TXFRMT; + acp_writel((rtd->xfer_resolution << 3), rtd->acp5x_base + ACP_HSTDM_ITER); + if (adata->tdm_mode == TDM_ENABLE) { + acp_writel(adata->tdm_fmt, adata->acp5x_base + ACP_HSTDM_TXFRMT); + val = acp_readl(adata->acp5x_base + ACP_HSTDM_ITER); + acp_writel(val | 0x2, adata->acp5x_base + ACP_HSTDM_ITER); + } + } + if (adata->i2ssp_play_stream && adata->i2ssp_play_stream->runtime) { + rtd = adata->i2ssp_play_stream->runtime->private_data; + config_acp5x_dma(rtd, SNDRV_PCM_STREAM_PLAYBACK); + acp_writel((rtd->xfer_resolution << 3), rtd->acp5x_base + ACP_I2STDM_ITER); + if (adata->tdm_mode == TDM_ENABLE) { + acp_writel(adata->tdm_fmt, adata->acp5x_base + ACP_I2STDM_TXFRMT); + val = acp_readl(adata->acp5x_base + ACP_I2STDM_ITER); + acp_writel(val | 0x2, adata->acp5x_base + ACP_I2STDM_ITER); } - acp_writel((rtd->xfer_resolution << 3), - rtd->acp5x_base + reg_val); } if (adata->capture_stream && adata->capture_stream->runtime) { - struct i2s_stream_instance *rtd = - adata->capture_stream->runtime->private_data; + rtd = adata->capture_stream->runtime->private_data; config_acp5x_dma(rtd, SNDRV_PCM_STREAM_CAPTURE); - switch (rtd->i2s_instance) { - case I2S_HS_INSTANCE: - reg_val = ACP_HSTDM_IRER; - frmt_val = ACP_HSTDM_RXFRMT; - break; - case I2S_SP_INSTANCE: - default: - reg_val = ACP_I2STDM_IRER; - frmt_val = ACP_I2STDM_RXFRMT; + acp_writel((rtd->xfer_resolution << 3), rtd->acp5x_base + ACP_HSTDM_IRER); + if (adata->tdm_mode == TDM_ENABLE) { + acp_writel(adata->tdm_fmt, adata->acp5x_base + ACP_HSTDM_RXFRMT); + val = acp_readl(adata->acp5x_base + ACP_HSTDM_IRER); + acp_writel(val | 0x2, adata->acp5x_base + ACP_HSTDM_IRER); } - acp_writel((rtd->xfer_resolution << 3), - rtd->acp5x_base + reg_val); } - if (adata->tdm_mode == TDM_ENABLE) { - acp_writel(adata->tdm_fmt, adata->acp5x_base + frmt_val); - val = acp_readl(adata->acp5x_base + reg_val); - acp_writel(val | 0x2, adata->acp5x_base + reg_val); + if (adata->i2ssp_capture_stream && adata->i2ssp_capture_stream->runtime) { + rtd = adata->i2ssp_capture_stream->runtime->private_data; + config_acp5x_dma(rtd, SNDRV_PCM_STREAM_CAPTURE); + acp_writel((rtd->xfer_resolution << 3), rtd->acp5x_base + ACP_I2STDM_IRER); + if (adata->tdm_mode == TDM_ENABLE) { + acp_writel(adata->tdm_fmt, adata->acp5x_base + ACP_I2STDM_RXFRMT); + val = acp_readl(adata->acp5x_base + ACP_I2STDM_IRER); + acp_writel(val | 0x2, adata->acp5x_base + ACP_I2STDM_IRER); + } } acp_writel(1, adata->acp5x_base + ACP_EXTERNAL_INTR_ENB); return 0;
