2019-05-07ASoC: rockchip: Fix an uninitialized variable compile warningTakashi Iwai1-1/+1
Paper over a trivial case leading to an uninitialized variable compile warning: sound/soc/rockchip/rockchip_pdm.c:179:3: warning: ‘clk_out’ may be used uninitialized in this function [-Wmaybe-uninitialized] Fixes: 624e8e00acaf ("ASoC: rockchip: pdm: fixup pdm fractional div") Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Mark Brown <broonie@kernel.org>
2019-04-04ASoC: rockchip: pdm: Mark RXFIFO_DATA as volatile and preciousSugar Zhang1-0/+13
This patch marks RXFIFO_DATA as precious to avoid being read outside a call from the driver, such as regmap debugfs Signed-off-by: Sugar Zhang <sugar.zhang@rock-chips.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2019-04-04ASoC: rockchip: pdm: Correct PDM_CTRL0 reg valueSugar Zhang1-2/+5
This patch fix the wrong reg value for rk322x/rk322xh, cuz there is no STORE JUSTIFIED MODE on it. on rk322x/rk322xh, the same bit means PDM_MODE/RESERVED, if the bit is set to RESERVED, the controller will not work.

2019-04-04ASoC: rockchip: pdm: adjust waterlevel in frame unitSugar Zhang1-1/+2
This patch make the waterlevel more reasonable, because the pdm controller share the single FIFO(128 entries) with each channel. adjust waterlevel in frame to meet the vad or dma frames request. Signed-off-by: Sugar Zhang <sugar.zhang@rock-chips.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2019-04-04ASoC: rockchip: pdm: add compatible for rk1808Sugar Zhang1-0/+2
This patch adds support for rk1808, the pdm controller is the same as rk3308. Signed-off-by: Sugar Zhang <sugar.zhang@rock-chips.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2019-04-04ASoC: rockchip: pdm: fixup pdm fractional divSugar Zhang1-42/+130
This patch adds support fractional div for rk3308. Signed-off-by: Sugar Zhang <sugar.zhang@rock-chips.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2019-04-04Merge branch 'asoc-5.1' into asoc-5.2Mark Brown1-1/+3
2019-04-04ASoC: rockchip: pdm: optimize clear logicSugar Zhang1-3/+2
There is no need to reset controller every time, do this once in pdm_probe. Signed-off-by: Sugar Zhang <sugar.zhang@rock-chips.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2019-04-04ASoC: rockchip: pdm: add default regsSugar Zhang1-0/+8
This patch add default regs value for controller. Signed-off-by: Sugar Zhang <sugar.zhang@rock-chips.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2019-04-04ASoC: rockchip: pdm: using left justified store modeSugar Zhang1-0/+1
This patch set left justified store mode default. Signed-off-by: Sugar Zhang <sugar.zhang@rock-chips.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2019-04-04ASoC: rockchip: pdm: change dma burst to 8Sugar Zhang1-1/+1
This patch decreases the transfer bursts to avoid the fifo overrun. Signed-off-by: Sugar Zhang <sugar.zhang@rock-chips.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2019-04-04ASoC: rockchip: pdm: fix regmap_ops hang issueSugar Zhang1-0/+2
This is because set_fmt ops maybe called when PD is off, and in such case, regmap_ops will lead system hang. enale PD before doing regmap_ops. Signed-off-by: Sugar Zhang <sugar.zhang@rock-chips.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2017-08-15ASoC: rockchip: constify snd_soc_dai_ops structuresJulia Lawall1-1/+1
These snd_soc_dai_ops structures are only stored in the ops field of a snd_soc_dai_driver structure, which is const. Thus, the snd_soc_dai_ops structures can be const too. Done with the help of Coccinelle. Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Mark Brown <broonie@kernel.org>
2017-06-13ASoC: rockchip: add support for pdm controllerSugar Zhang1-0/+516
The Pulse Density Modulation Interface Controller (PDMC) is a PDM interface controller and decoder that support PDM format. It integrates a clock generator driving the PDM microphone and embeds filters which decimate the incoming bit stream to obtain most common audio rates.
