* | ASoC: snappercl15: convert to use snd_soc_register_card()Mika Westerberg2011-09-16
| | | | | | | | | | | | | | | | | | | | Current method for machine driver to register with the ASoC core is to use snd_soc_register_card() instead of creating a "soc-audio" platform device.

* | ASoC: support sample sizes properly in the WM8776 codec driverTimur Tabi2011-09-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use snd_pcm_format_width() to determine the sample size, instead of checking specify sample formats and assuming that those are the only valid format. This change adds support for big-endian architectures (which use the _BE formats) and the packed 24-bit format (SNDRV_PCM_FORMAT_S24_3xE).

* | ASoC: improve asynchronous mode support in the fsl_ssi driverTimur Tabi2011-09-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Freescale SSI audio controller supports "synchronous" and "asynchronous" modes. In synchronous mode, playback and capture use the same input clock, so sample rates must be the same during simultaneous playback and capture. Unfortunately, the code which supports asynchronous mode is just broken in various ways. In particular, it was constraining sample sizes as well as the sample rate. The fix also allows us to simplify the code by eliminating the 'asynchronous', 'playback', and 'capture' variables that were used to keep track of playback and capture streams. Unfortunately, it turns out that simulataneous playback and record does not actually work on the only platform that supports asynchronous mode: the Freescale P1022DS reference board. If a second stream is started, the SSI grinds to halt for both streams. This is true even if the P1022 is configured for synchronous mode, so it's likely a hardware problem that needs to be worked around.

* | ASoC: Disable WM8996 CPVDD supply when not in useMark Brown2011-09-14
| | | | | | | | | | | | | | | | | | | | The WM8996 only requires CPVDD when the charge pump is active so control it separately to the other supplies, only enabling it when the charge pump is active. This will result in a small power saving on systems which are able to provide independent software control of the supply.

* | regulator: Implement deferred disable supportMark Brown2011-09-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is a reasonably common pattern for hardware to require some delay after being quiesced before the disable has finalised, especially in mixed signal devices. For example, an active discharge may be required to ensure that the circuit starts up again in a known state. Avoid having to implement such delays in the regulator API by providing regulator_deferred_disable() which will do a regulator_disable() a specified number of milliseconds after it is called. Due to the reference counting done on regulators a deferred disable can be cancelled by doing another regulator_enable().

* | ASoC: ad193x: Setup regmap read and write flag masks for SPILars-Peter Clausen2011-09-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently register read-back for the ad193x is broken, because it expects bit 0 of the upper byte to be set to indicate a read operation, while the regmap default for SPI is to use bit 7. This patch also addresses another oddity of the device. There are SPI and I2C versions of this codec. In both cases the registers are 8-bit wide and numbered from 0x0 to 0x10, but in the SPI case there is also a so called 'global address' which is prefixed in-front of the register address. The global address mimics I2C behaviour and includes a static device address the and the read/write flag. This basically extends the register address to an 16-bit value numbered from 0x800 to 0x810. These are the register numbers which are currently used by the driver. This works, because I2C will ignore the upper 8 bits of the register, but it is still a bit confusing, as there are no such register numbers in the I2C case. The approach taken by this patch is to number the registers from 0x00 to 0x10 and encode the global address for SPI mode into the read and write flag masks.

| * | regmap: Allow drivers to specify register defaultsMark Brown2011-08-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is useful for the register cache code to be able to specify the default values for the device registers. The major use is when restoring the register cache after suspend, knowing the register defaults allows us to skip registers that are at their default values when we resume which can be a substantial win on larger modern devices. For some devices (mostly older ones) the hardware does not support readback so the only way we can know the values is from code and so initializing the cache with default values makes it much easier for drivers work with read/modify/write updates.

| * | regmap: Add precious registers to the driver interfaceMark Brown2011-08-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some devices are sensitive to reads on their registers, especially for things like clear on read interrupt status registers. Avoid creating problems with these with things like debugfs by allowing drivers to tell the core about them. If a register is marked as precious then the core will not internally generate any reads of it. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is currently unused but we need to know which registers exist and their properties in order to implement diagnostics like register map dumps and the cache features. We use callbacks partly because properties can vary at runtime (eg, through access locks on registers) and partly because big switch statements are a good compromise between readable code and small data size for providing information on big register maps.

* | | ASoC: Allow source specification for CODEC level sysclkMark Brown2011-08-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Similarly to PLLs/FLLs some modern CODECs provide selectable system clock sources. When the clock is the clock for a DAI we do not usually need to identify which clock is being configured so can use clk_id for the source clock but with CODEC wide system clocks we will need to specify both the clock being configured and the source. Add a source argument to the CODEC driver set_sysclk() operation to reflect this. As this operation is not as widely used as the DAI set_sysclk() operation the change is not very invasive. We probably ought to go and make the same alternation for DAIs at some point. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
