2012-05-07ASoC: dapm: Ensure power gets managed for line widgetsMark Brown
commit 7e1f7c8a6e517900cd84da1b8ae020f08f286c3b upstream. Line widgets had not been included in either the power up or power down sequences so if a widget had an event associated with it that event would never be run. Fix this minimally by adding them to the sequences, we should probably be doing away with the specific widget types as they all have the same priority anyway.

2012-04-02ASoC: pxa-ssp: atomically set stream active masksDaniel Mack
commit 273b72c8ce6b28df6b49423d775c3e59072c73c5 upstream. PXA's SSP engine fails to take its current channel phase into account when enabling a stream while the engine is already running. This results in randomly swapped left/right channels on either the record or the playback side, depending on which one was enabled first. The following patch fixes this by factoring out the bit field modifications in question to a separate function that pauses the engine temporarily, modifies the bits and kicks it off again afterwards. Appearantly, a transition of SSCR0_SSE syncs both directions properly. The patch has been rolled out to quite a number of devices over the last weeks and seems to fix the issue reliably.

commit 5ed80a75b248bfaf840ea6b38f941edcf6ee7dc7 upstream. According to i.MX27 Reference Manual (p 1593) TXBIT0 bit selects whether the most significant or the less significant part of the data word written to the FIFO is transmitted. As DSP_A is the same as DSP_B with a data offset of 1 bit, it doesn't make any sense to remove TXBIT0 bit here.

commit 7679e42ec833ed70aa34790a5f39dcb7e5bda4fe upstream. Recent enhancements in the bias management means that we might not be in standby when the CODEC is idle and can have active widgets without being in full power mode but the shutdown functionality assumes these things. Add checks for the bias level at each stage so that we don't do transitions other than the ON->PREPARE->STANDBY->OFF ones that the drivers are expecting.

2011-12-21ASoC: core: Don't schedule deferred_resume_work twiceStephen Warren
commit 82e14e8bdd88b69018fe757192b01dd98582905e upstream. For cards that have two or more DAIs, snd_soc_resume's loop over all DAIs ends up calling schedule_work(deferred_resume_work) once per DAI. Since this is the same work item each time, the 2nd and subsequent calls return 0 (work item already queued), and trigger the dev_err message below stating that a work item may have been lost. Solve this by adjusting the loop to simply calculate whether to run the resume work immediately or defer it, and then call schedule work (or not) one time based on that. Note: This has not been tested in mainline, but only in chromeos-2.6.38; mainline doesn't support suspend/resume on Tegra, nor does the mainline Tegra ASoC driver contain multiple DAIs. It has been compile-checked in mainline.

commit cefcc03ffc9527dde56807339edb1719c8dbae5f upstream. Allow userspace applications to do more parameter setting by providing a more complete stub DMA driver specifying a wildcard set of formats and channels and essentially random values for the DMA parameters. This is required for useful runtime operation of the dummy DMA driver until we are able to figure out how to power up links and do hw_params() from DAPM. Sending to stable as without this the dummy driver is not terribly useful.

commit 34c869855a28af3c6031d29e2267b5a3cce0d67d upstream. Attempt to change McBSP CLKS source while another stream is active is not safe after commit d135865 ("OMAP: McBSP: implement functional clock switching via clock framework") in 2.6.37. CLKS parent clock switching using clock framework have to idle the McBSP before switching and then activate it again. This short break can cause a DMA transaction error to already running stream which halts and recovers only by closing and restarting the stream. This goes more fatal after commit e2fa61d ("OMAP3: l3: Introduce l3-interconnect error handling driver") in 2.6.39 where l3 driver detects a severe timeout error and does BUG_ON(). Fix this by not changing any configuration in omap_mcbsp_dai_set_dai_sysclk if the McBSP is already active. This test should have been here just from the beginning anyway.

commit 29591ed4ac6fe00e3ff23b5be0cdc7016ef9c47e upstream. Two issues were preventing module snd-soc-tegra-wm8903.ko from being removed and re-inserted: a) The speaker-enable GPIO is hosted by the WM8903 chip. This GPIO must be freed before snd_soc_unregister_card() is called, because that triggers wm8903.c:wm8903_remove(), which calls gpiochip_remove(), which then fails if any of the GPIOs are in use. To solve this, free all GPIOs first, so the code doesn't care where they come from. b) We need to call snd_soc_jack_free_gpios() to match the call to snd_soc_jack_add_gpios() during initialization. Without this, the call to snd_soc_jack_add_gpios() fails during any subsequent modprobe and initialization, since the GPIO and IRQ are already registered. In turn, this causes the headphone state not to be monitored, so the headphone is assumed not to be plugged in, and the audio path to it is never enabled.

2011-08-15ASoC: sgtl5000: fix cache handlingWolfram Sang
commit 151798f872d6b386d82cd1707ad703e981fef8f2 upstream. Cache handling in this driver is broken. The chip has 16-bit registers, yet the register numbers also increase by 2 per register, i.e. there are only even-numbered registers. The cache in this driver, though, simply increments register numbers, so it does need some mapping as seen in sgtl5000_restore_regs(), note the '>> 1': snd_soc_write(codec, SGTL5000_CHIP_LINREG_CTRL, cache[SGTL5000_CHIP_LINREG_CTRL >> 1]); That, of course, won't work with snd_soc_update_bits(). (Thus, we won't even notice the missing register 0x1c in the default regs which shifted all follwing registers to wrong values.) Noticed on the MX28EVK where enabling the regulators simply locked up the chip. Refactor the routines and use a properly sized default_regs array which matches the register layout of the underlying chip, i.e. create a truly flat cache. This also saves some code which should make up for the bigger array a little. When soc-core will somewhen have another cache type which handles a step size, this conversion will also ease the transition.

2011-08-04ASoC: Mark cache as dirty when suspendingMark Brown
commit 7be4ba24a3ea53bc8ade841635e4d4a59e98ceb5 upstream. Since quite a few drivers are not managing to flag the cache as needing to be resynced after suspend and it's a reasonable thing to do flag the cache as needing sync automatically when suspending. The expectation is that systems will mainly only keep the CODEC powered when doing audio through the CODEC so we won't actually suspend the device anyway; drivers which want to can override this behaviour when they resume.

2011-08-04ASoC: davinci: fix codec start and stop functionsRajashekhara, Sudhakar
commit 3012f43eaf7592d8121426918e43e3b5db013aff upstream. According to DM365 voice codec data sheet at [1], before starting recording or playback, ADC/DAC modules should follow a reset and enable cycle. Writing a 1 to the ADC/DAC bit in the register resets the module and clearing the bit to 0 will enable the module. But the driver seems to be doing the reverse of it.

commit 82d1d521036eb3f5aae48b847f939d99a44c18bb upstream. In davinci_vcif_trigger() function, a break() statement was missing causing the davinci_vcif_stop() function to be called as a fallback after calling davinci_vcif_start().

2011-07-17ASoC: Correct WM8994 MICBIAS supply widget hookupMark Brown
The WM8994 and WM8958 series of devices have two MICBIAS supplies rather than one, the current widget actually manages the microphone detection control register bit (which is managed separately by the relevant API). Fix this, hooking the relevant supplies up to the MICBIAS1 and MICBIAS2 widgets. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Cc: stable@kernel.org
