2021-03-24ASoC: fsl_easrc: Don't use devm_regmap_init_mmio_clkShengjiu Wang1-2/+1
When there is power domain bind with mem clock, The call flow: devm_regmap_init_mmio_clk - clk_prepare() - clk_pm_runtime_get() cause the power domain of clock always be enabled after regmap_init(). which impact the power consumption. So use devm_regmap_init_mmio instead of devm_regmap_init_mmio_clk,but explicitly enable clock when it is used.

2020-06-22ASoC: soc-component: merge snd_soc_component_read() and ↵Kuninori Morimoto1-4/+1
snd_soc_component_read32() We had read/write function for Codec, Platform, etc, but these has been merged into snd_soc_component_read/write(). Internally, it is using regmap or driver function. In read case, each styles are like below regmap ret = regmap_read(..., reg, &val); driver function val = xxx->read(..., reg); Because of this kind of different style, to keep same read style, when we merged each read function into snd_soc_component_read(), we created snd_soc_component_read32(), like below. commit 738b49efe6c6 ("ASoC: add snd_soc_component_read32") (1) val = snd_soc_component_read32(component, reg); (2) ret = snd_soc_component_read(component, reg, &val); Many drivers are using snd_soc_component_read32(), and some drivers are using snd_soc_component_read() today. In generally, we don't check read function successes, because, we will have many other issues at initial timing if read function didn't work. Now we can use soc_component_err() when error case. This means, it is easy to notice if error occurred. This patch aggressively merge snd_soc_component_read() and _read32(), and makes snd_soc_component_read/write() as generally style. This patch do 1) merge snd_soc_component_read() and snd_soc_component_read32() 2) it uses soc_component_err() when error case (easy to notice) 3) keeps read32 for now by #define 4) update snd_soc_component_read() for all drivers Because _read() user drivers are not too many, this patch changes all user drivers.

EASRC (Enhanced Asynchronous Sample Rate Converter) is a new IP module found on i.MX8MN. It is different with old ASRC module. The primary features for the EASRC are as follows: - 4 Contexts - groups of channels with an independent time base - Fully independent and concurrent context control - Simultaneous processing of up to 32 audio channels - Programmable filter charachteristics for each context - 32, 24, 20, and 16-bit fixed point audio sample support - 32-bit floating point audio sample support - 8kHz to 384kHz sample rate - 1/16 to 8x sample rate conversion ratio Signed-off-by: Shengjiu Wang <shengjiu.wang@nxp.com> Signed-off-by: Cosmin-Gabriel Samoila <cosmin.samoila@nxp.com> Acked-by: Nicolin Chen <nicoleotsuka@gmail.com> Link: https://lore.kernel.org/r/260d7a9fbddf9fa90760d30095df60a4c25fd0a1.1587038908.git.shengjiu.wang@nxp.com Signed-off-by: Mark Brown <broonie@kernel.org>
