2012-11-02ASoC: mxs-saif: Fix channel swap for 24-bit formatFabio Estevam1-4/+12
Playing 24-bit format file leads to channel swap on mx28 and the reason is that the current driver performs one write/read to/from the SAIF_DATA register to trigger the transfer. This approach works fine for S16_LE case because SAIF_DATA is a 32-bit register and thus is capable of storing the 16-bit left and right channels, but for the S24_LE case it can only store one channel, so in order to not lose the FIFO sync an extra read/write is needed.

2012-07-24ASoC: mxs-saif: set a base clock rate for EXTMASTER mode workDong Aisheng1-1/+15
Set an initial clock rate for the saif internal logic to work properly. This is important when working in EXTMASTER mode that uses the other saif's BITCLK&LRCLK but it still needs a basic clock which should be fast enough for the internal logic.

2012-07-24ASoC: mxs-saif: fix clock prepare and enable unbalance issueDong Aisheng1-0/+10
Currently we directly call a clock_enable in trigger function without a clk_prepare as pair first. This will cause system hang immediately when run capture because the clock was not prepared(playback does not hang because the clock was prepared already by get_mclk before), a warning message in clock framework may cause a deadlock to reclaim clock lock (see: pl011_console_write). Here we prepare clock first in hw_param, then enable it in trigger function to guarantee the balance.

2012-06-20ASoC: dmaengine-pcm: Rename and deprecate snd_dmaengine_pcm_pointerLars-Peter Clausen1-1/+1
Currently the sound dmaengine pcm helper functions implement the pcm_pointer callback by trying to count the number of elapsed periods. This is done by advancing the stream position in the dmaengine callback by one period. Unfortunately there is no guarantee that the callback will be called for each elapsed period. It may be possible that under high system load it is only called once for multiple elapsed periods. This patch renames the current implementation and documents its shortcomings and that it should not be used anymore in new drivers. The next patch will introduce a new snd_dmaengine_pcm_pointer which will be implemented based on querying the current stream position from the dma device.

2012-06-03ASoC: make snd_soc_dai_link more symmetricalStephen Warren1-1/+1
Prior to this patch, the CPU side of a DAI link was specified using a single name. Often, this was the result of calling dev_name() on the device providing the DAI, but in the case of a CPU DAI driver that provided multiple DAIs, it needed to mix together both the device name and some device-relative name, in order to form a single globally unique name. However, the CODEC side of the DAI link was specified using separate fields for device (name or OF node) and device-relative DAI name. This patch allows the CPU side of a DAI link to be specified in the same way as the CODEC side, separating concepts of device and device-relative DAI name. I believe this will be important in multi-codec and/or dynamic PCM scenarios, where a single CPU driver provides multiple DAIs, while also booting using device tree, with accompanying desire not to hard-code the CPU side device's name into the original .cpu_dai_name field. Ideally, both the CPU DAI and CODEC DAI loops in soc_bind_dai_link() would now be identical. However, two things prevent that at present: 1) The need to save rtd->codec for the CODEC side, which means we have to search for the CODEC explicitly, and not just the CODEC side DAI. 2) Since we know the CODEC side DAI is part of a codec, and not just a standalone DAI, it's slightly more efficient to convert .codec_name/ .codec_of_node into a codec first, and then compare each DAI's .codec field, since this avoids strcmp() on each DAI's CODEC's name within the loop. However, the two loops are essentially semantically equivalent. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-05-23Merge tag 'sound-3.5' of ↵Linus Torvalds5-54/+116
git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "This is the first big chunk for 3.5 merges of sound stuff. There are a few big changes in different areas. First off, the streaming logic of USB-audio endpoints has been largely rewritten for the better support of "implicit feedback". If anything about USB got broken, this change has to be checked. For HD-audio, the resume procedure was changed; instead of delaying the resume of the hardware until the first use, now waking up immediately at resume. This is for buggy BIOS. For ASoC, dynamic PCM support and the improved support for digital links between off-SoC devices are major framework changes. Some highlights are below: * HD-audio - Avoid accesses of invalid pin-control bits that may stall the codec - V-ref setup cleanups - Fix the races in power-saving code - Fix the races in codec cache hashes and connection lists - Split some common codes for BIOS auto-parser to hda_auto_parser.c - Changed the PM resume code to wake up immediately for buggy BIOS - Creative SoundCore3D support - Add Conexant CX20751/2/3/4 codec support * ASoC - Dynamic PCM support, allowing support for SoCs with internal routing through components with tight sequencing and formatting constraints within their internal paths or where there are multiple components connected with CPU managed DMA controllers inside the SoC. - Greatly improved support for direct digital links between off-SoC devices, providing a much simpler way of connecting things like digital basebands to CODECs. - Much more fine grained and robust locking, cleaning up some of the confusion that crept in with multi-component. - CPU support for nVidia Tegra 30 I2S and audio hub controllers and ST-Ericsson MSP I2S controolers - New CODEC drivers for Cirrus CS42L52, LAPIS Semiconductor ML26124, Texas Instruments LM49453. - Some regmap changes needed by the Tegra I2S driver. - mc13783 audio support. * Misc - Rewrite with module_pci_driver() - Xonar DGX support for snd-oxygen - Improvement of packet handling in snd-firewire driver - New USB-endpoint streaming logic - Enhanced M-audio FTU quirks and relevant cleanups - Increment the support of OSS devices to 256 - snd-aloop accuracy improvement There are a few more pending changes for 3.5, but they will be sent slightly later as partly depending on the changes of DRM." Fix up conflicts in regmap (due to duplicate patches, with some further updates then having already come in from the regmap tree).

This timeout happens because clk_set_rate will result in writing to the DIV bits of register HW_CLKCTRL_SAIF0 with the saif clock gated (CLKGATE bit set to one). MX28 Reference states the following about CLKGATE: "The DIV field can change ONLY when this clock gate bit field is low." So call clk_prepare_enable prior to clk_set_rate to fix this problem. After this change the mxs-saif driver can be correctly probed and audio is functional.

1. add different clkmux mode handling SAIF can use two instances to implement full duplex (playback & recording) and record saif may work on EXTMASTER mode which is using other saif's BITCLK&LRCLK. The clkmux mode could be set in pdata->init() in mach-specific code. For generic saif driver, it only needs to know who is his master and the master id is also provided in mach-specific code. 2. support playback and capture simutaneously however the sample rates can not be different due to hw limitation.

2011-08-22sound/soc/mxs/mxs-saif.c: add missing kfreeJulia Lawall1-2/+3
Move the test on pdev->id before the kzalloc to avoid requiring kfree when the test fails. This fix was suggested by Wolfram Sang. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ identifier x; expression E1!=0,E2,E3,E4; statement S; iterator I; @@ ( if (...) { ... when != kfree(x) when != x = E3 when != E3 = x * return ...; } ... when != x = E2 when != I(...,x,...) S if (...) { ... when != x = E4 kfree(x); ... return ...; } ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Acked-by: Dong Aisheng <b29396@freescale.com> Reviewed-by: Wolfram Sang <w.sang@pengutronix.de> Acked-by: Liam Girdwood <lrg@ti.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2011-08-22ASoC: mxs-saif: clear clk gate first before register settingDong Aisheng1-10/+12
Saif needs clear clk gate first before writing registers or the write will not success. The original xx_get_mclk function clear clk gate after mclk setting that may cause the former mclk setting unwork, then the real output mclk maybe inaccurate. Placing the clear before setting mclk to avoid such an issue. We also have to clear clk gate in startup instead of in prepare function.

2011-07-28ASoC: mxs: add mxs-sgtl5000 machine driverDong Aisheng1-0/+165
The driver only supports playback firstly. For recording, as we have to use two saif instances to implement full duplex (playback & recording) due to hardware limitation, we need to figure out a good design to fit in ASoC.
