clk_get() returns a pointer to the struct clk or an ERR_PTR(). This patch also use PTR_ERR() for return value. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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(). Signed-off-by:

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. Signed-off-by:

Add the externally visible interface introduced by Lars-Peter's commit 6f3064 (regmap: Add support for device specific write and read flag masks) separately in order to allow merge into other subsystems for integration with drivers. Drivers relying on this feature will not be functional until they are merged with the implementation. Signed-off-by:

snd_pcm_hw_constraint_integer() could return -1, in this case, sst platform is not opened successfully. However the corresponding close callback isn't able to be called later on to release these two allocated memories, thus resulting in memory leak. This patch moves the check for hardware contraints earlier, thus resolving this issue. Signed-off-by:

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: -

Currently the condition for these WARN_ONs is reversed and they are placed before the actual check whether we are going to write to that register. So if the codec implements the register_writable callback we'll get a warning for each writable register when syncing the register cache. While we are at it change the check to use snd_soc_codec_writable_register instead of open-coding it. Signed-off-by:

Although the McASP supports sign-extending samples in RX or TX [1]; the davinci-mcasp driver does not touch the {R,X}PBIT or {R,X}PAD field of the {R,X}FMT registers meaning that the McASP will serialize the bytes it is given regardless of their signedness. So supporting unsigned formats is as simple as adding them to the metadata of the davinci-mcasp driver. Update the FMTBITs reported in the snd_soc_dai_driver and also update the case statements in davinci-mcasp's hw_params() function so that the McASP can be connected to CODECs that use unsigned values.
