2015-01-12ASoC: rsnd: add recovery support for under/over flow error on SRCKuninori Morimoto1-0/+1
L/R channel will be switched if under/over flow error happen on Renesas R-Car sound device by the HW bugs. Then, HW restart is required for salvage. This patch add salvage support for SRC.

2014-12-07ASoC: rsnd: rename SSI function name of PIOKuninori Morimoto1-4/+4
Current R-Car sound SSI PIO/DMA mode are using interrupt. it is no longer "xxx_pio_xxx", rename it. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-06-28ASoC: rsnd: SSI + DMA can select BUSIFKuninori Morimoto1-0/+1
Sound data needs to be sent to R-Car sound SSI when playback. But, there are 2 interfaces for it. 1st is SSITDR/SSIRDR which are mapped on SSI. 2nd is SSIn_BUSIF which are mapped on SSIU. 2nd SSIn_BUSIF is used when DMA transfer, and it is always used if sound data came from via SRC. But, we can use it when SSI+DMA case too. (Current driver is assuming 1st SSITDR/SSIRDR for it) 2nd SSIn_BUSIF can be used as FIFO. This is very helpful/useful for SSI+DMA. But DMA address / DMA ID are not same between 1st/2nd cases. This patch care about these settings.

2014-05-08ASoC: rsnd: remove compatibility codeKuninori Morimoto1-19/+3
Now, all platform is using new style rsnd_dai_platform_info. Keeping compatibility is no longer needed. We can cleanup code. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-03-05ASoC: rsnd: rename scu to srcKuninori Morimoto1-7/+11
R-Car sound has SCU unit which has SRC/CTU/MIX/DVC, and current rsnd driver has scu.c and scu module. Current scu.c has SRC support only. My first concept was control these feature on scu.c but, it become difficult and un-understandable now. This patch rename scu to src Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-03-05ASoC: rsnd: Get correct SCU IDKuninori Morimoto1-0/+1
Current rsnd driver is assuming that SCU/SRU ID is same as SSIU/SSI ID, because Gen1 can't select it. But, Gen2 can select it. The SCU/SRU/SSIU/SSI pair depends on the platform. This patch get correct SCU ID from platform info. To keep compatible, it still assuming SCU ID = SSI ID if platform doesn't have info Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-03-05ASoC: rsnd: add struct rsnd_dai_platform_infoKuninori Morimoto1-1/+16
R-Car sound DAI consists from SSI/SCU/SSIU/SRU... Current R-Car sound DAI is decided from these settings, but it is intuitively unclear, and is not good design for DT support. This patch adds new rsnd_dai_platform_info to solve this issue. But now, many platform is using this driver without rsnd_dai_platform_info. So, this patch still supports DAI settings via SSI to keep compatible. It will be removed in next Linux version.

6f3ab6c1c022e7a4877d38940cd45ae7804a15e2 (ASoC: rsnd: remove pin sync option) added unused RSND_SSI_CLK_FROM_ADG flag. It should remove RSND_SSI_SYNC. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-02-03ASoC: rsnd: add Gen2 SRC and DMAEngine supportKuninori Morimoto1-0/+6
Renesas sound Gen2 has SRC (= Sampling Rate Converter) which needs 2 DMAC. The data path image when you use SRC on Gen2 is [mem] -> Audio-DMAC -> SRC -> Audio-DMAC-peri-peri -> SSIU -> SSI This patch support SRC and DMAEnine. It is tested on R-Car H2 Lager board Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-02-03ASoC: rsnd: remove pin sync optionKuninori Morimoto1-0/+1

Pull ARM SoC board updates from Olof Johansson: "This branch is reducing in size for every release since most board-related changes have started happening in devicetrees now. Still, we have some things going on here. * Renesas platforms are still adding a bit more legacy device support, something that should trail off shortly as they move to full DT * We group most defconfig updates into this branch out of old habits * Removal of legacy OMAP2 platforms over to DT continues, and a handful of old code is being removed here" * tag 'boards-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (94 commits) ARM: dts: OMAP2: fix interrupt number for rng ARM: dts: Split omap3 pinmux core device ARM: dts: Add omap specific pinctrl defines to use padconf addresses ARM: bcm2835: bcm2835_defconfig updates ARM: msm_defconfig: Enable restart driver defconfig: msm_defconfig: Enable CONFIG_ARCH_MSM8974 ARM: msm: Add support for APQ8074 Dragonboard ARM: exynos_defconfig: Enable S2MPS11 voltage regulator ARM: tegra: Enable DRM panel support ARM: shmobile: mackerel: Fix USBHS pinconf entry ARM: shmobile: Let Koelsch multiplatform boot with Koelsch DTB ARM: shmobile: Let Lager multiplatform boot with Lager DTB ARM: shmobile: Remove non-multiplatform Koelsch reference support ARM: shmobile: Remove non-multiplatform Lager reference support ARM: shmobile: koelsch-reference: Instantiate clkdevs for SCIF and CMT ARM: shmobile: lager-reference: Instantiate clkdevs for SCIF and CMT ARM: shmobile: koelsch-reference: Remove duplicate CCF initialization ARM: shmobile: lager-reference: Enable multiplaform kernel support ARM: shmobile: armadillo: Set backlight enable GPIO ARM: shmobile: Koelsch: add Ether support ...

2013-12-31ASoC: rsnd: add SRC (Sampling Rate Converter) supportKuninori Morimoto1-0/+1
This patch adds SRC support to Renesas sound driver. SRC converts sampling rate between codec <-> cpu. It needs special codec chip, or very simple DA/AD converter to use it.

2013-10-20ASoC: rcar: add rsnd_scu_hpbif_is_enable()Kuninori Morimoto1-1/+0
Current SSI needs RSND_SSI_DEPENDENT flag to decide dependent/independent mode. And SCU needs RSND_SCU_USE_HPBIF flag to decide HPBIF is enable/disable. But these 2 means same things.

2013-08-06ASoC: rsnd: SSI supports DMA transferKuninori Morimoto1-3/+4

Current rsnd driver is using struct rsnd_dai_platform_info so that indicate sound DAI information (playback/capture SSI ID). But, SSI settings were also required separately. Thus, platform settings was very un-understandable. This patch adds dai_id to SSI settings, and removed rsnd_dai_platform_info.

2013-07-28ASoC: add Renesas R-Car SSI featureKuninori Morimoto1-1/+22
Renesas R-Car series sound circuit consists of SSI and its peripheral. But this peripheral circuit is different between R-Car Generation1 (E1/M1/H1) and Generation2 (E2/M2/H2) (Actually, there are many difference in Generation1 chips) As 1st protype, this patch adds SSI feature on this driver. But, it is PIO sound playback support only at this point.

But this peripheral circuit is different between R-Car Generation1 (E1/M1/H1) and Generation2 (E2/M2/H2) (Actually, there are many difference in Generation1 chips) The main difference between Gen1 and Gen2 are 1) register offset, 2) data path In order to control Gen1/Gen2 by same method, this patch adds gen.c.

(Actually, there are many difference in Generation1 chips) Basically, for the future, Renesas R-Car series will use Gen2 style sound circuit, but driver should care Gen1 also.
