2011-06-06ASoC: AD1836: Add input gain control for ADC2Lars-Peter Clausen
The AD1836 has a PGA for its second ADC. This patch adds a control for adjusting the the gain of the PGA. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Acked-by: Liam Girdwood <lrg@ti.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2011-06-06ASoC: AD1836: Remove unused fields from private structLars-Peter Clausen
The control_type field is never used, so it can be removed. The control_data field is used to initialize the codec's control_data field, but since this is also done by the snd-soc-cache core, the redundant assignment can be removed and the field can be dropped.

2011-06-06ASoC: AD1836: Add AD1835/AD1837/AD1838/AD1839 supportLars-Peter Clausen
The AD183X codec devices are mostly register compatible and can easily be supported by the same driver. The main difference between those devices is the number of DACs and ADCs. This patch adjusts the driver to allocate the controls, DAPM widgets and routes for the DACs and ADCs dynamically based on the chip type. The AD1836 is a bit special in that it supports different modes for its second ADC, so it needs some special handling. Right now the driver hardcodes the mode to the differential PGA mode.

2011-06-06ASoC: AD1836: Add ADC/DAC controls helper macrosLars-Peter Clausen
The different ADC and DAC controls follow the same scheme, so add some helper macros for declaring them. This should make the code a bit more readable and also decreases the code size a bit.

2011-06-06ASoC: Manage Speyside system clocking only in bias managementMark Brown
Now that the CODEC driver supports it defer configuration of the system clock until bias management which is a much more idiomatic place to do system power control and makes things a lot more happy when we're using both interfaces.

2011-06-06ASoC: Don't bring the CODEC up to full power for supplies and biasesMark Brown
If the only widgets active within a CODEC are supplies and micbiases we are not passing audio, we are probably just doing microphone detection. This will not generally require either fully accurate reference voltages or much power so If this turns out to be unsuitable for some systems we can provide a facility to override this decision.

2011-06-06ASoC: Specify target bias state directly as a bias stateMark Brown
Rather than a simple flag to say if we want the DAPM context to be at full power specify the target bias state. This should have no current effect but is a bit more direct and so makes it easier to change our decisions about the which bias state to go into in future.

2011-06-06ASoC: Allow WM8915 BCLK calculation outside hw_params()Mark Brown
Allow more dynamic management of the device clocking by allowing BCLK to be calculated when we set SYSCLK. This means that if the system is idle when hw_params() runs then we don't try to use the SYSCLK used in that case to set up the BCLK dividers, we can instead wait until a later point such as bias level configuration. This makes it easier to manage low power modes. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@ti.com>

2011-06-06ASoC: Error out when FLL lock interrupt is not delivered on WM8915Mark Brown
When the FLL locks on the WM8915 an interrupt is generated. For safety error out if we don't get that interrupt when the IRQ output of the WM8915 is hooked up. Since we *really* expect an interrupt but the threaded IRQ handler may take a bit longer than expected to get scheduled also dramatically increase the delay in this case.

2011-06-01ASoC: Remove internally generated WM8915 suppliesMark Brown
DCVDD and MICVDD are intended to be (and almost always are) generated by on-board LDOs which are transparently controlled by the driver so we shouldn't really be requesting them from the regulator API.

2011-05-29eCryptfs: Cleanup and optimize ecryptfs_lookup_interpose()Tyler Hicks
ecryptfs_lookup_interpose() has turned into spaghetti code over the years. This is an effort to clean it up. - Shorten overly descriptive variable names such as ecryptfs_dentry - Simplify gotos and error paths - Create helper function for reading plaintext i_size from metadata It also includes an optimization when reading i_size from the metadata. A complete page-sized kmem_cache_alloc() was being done to read in 16 bytes of metadata. The buffer for that is now statically declared. Signed-off-by: Tyler Hicks <tyhicks@linux.vnet.ibm.com>
