ASoC: cs4270: Remove redundant big endian formats

2022-05-09T11:46:10Z

The CODEC already provides the endianness flag on its snd_soc_component_driver structure, specifying it is ambivalent to endian. The core will expand the formats to cover both endian types, as such remove the redundant specification of both endians.

ASoC: cs*: use simple i2c probe function

2022-04-05T09:23:19Z

The i2c probe functions here don't use the id information provided in their second argument, so the single-parameter i2c probe function ("probe_new") can be used instead. This avoids scanning the identifier tables during probes.

ASoC: codecs: cs*: merge .digital_mute() into .mute_stream()

2020-07-16T22:06:19Z

snd_soc_dai_digital_mute() is internally using both mute_stream() (1) or digital_mute() (2), but the difference between these 2 are only handling direction. We can merge digital_mute() into mute_stream int snd_soc_dai_digital_mute(xxx, int direction) { ... else if (dai->driver->ops->mute_stream) (1) return dai->driver->ops->mute_stream(xxx, direction); else if (direction == SNDRV_PCM_STREAM_PLAYBACK && dai->driver->ops->digital_mute) (2) return dai->driver->ops->digital_mute(xxx); ... } Signed-off-by: Kuninori Morimoto Reviewed-by: Peter Ujfalusi Link: https://lore.kernel.org/r/87r1tlwiwe.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown

ASoC: cs4270: pull reset GPIO low then high

2020-04-07T14:29:54Z

Pull the RST line low then high when initializing the driver, in order to force a reset of the chip. Previously, the line was not pulled low, which could result in the chip registers not resetting to their default values on boot.

treewide: remove redundant IS_ERR() before error code check

2020-02-04T03:05:27Z

'PTR_ERR(p) == -E*' is a stronger condition than IS_ERR(p). Hence, IS_ERR(p) is unneeded. The semantic patch that generates this commit is as follows: // @@ expression ptr; constant error_code; @@ -IS_ERR(ptr) && (PTR_ERR(ptr) == - error_code) +PTR_ERR(ptr) == - error_code // Link: http://lkml.kernel.org/r/20200106045833.1725-1-masahiroy@kernel.org Signed-off-by: Masahiro Yamada Cc: Julia Lawall Acked-by: Stephen Boyd [drivers/clk/clk.c] Acked-by: Bartosz Golaszewski [GPIO] Acked-by: Wolfram Sang [drivers/i2c] Acked-by: Rafael J.

ASoC: cs4270: Set auto-increment bit for register writes

2019-03-21T14:46:20Z

The CS4270 does not by default increment the register address on consecutive writes. During normal operation it doesn't matter as all register accesses are done individually. At resume time after suspend, however, the regcache code gathers the biggest possible block of registers to sync and sends them one on one go. To fix this, set the INCR bit in all cases.
