2011-10-14ASoC: core: Add flag to ignore pmdown_time at pcm_closePeter Ujfalusi1-0/+1
With this flag codec drivers can indicate that it is desired to ignore the pmdown_time for DAPM shutdown sequence when playback stream is stopped. The DAPM sequence will be executed without delay in this case. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

Both Headset DAC need to be turned on/off at the same time before any of the output drivers are enabled (HS Left/Right, Earpiece). Move the HS DAC enable code to sequenced DAPM_SUPPLY, and attach it to the DACs. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

If the client only interested, if any of the vibra channels enabled, or if any of the channels are set to receive audio data via PDM. This function targets mainly the vibra driver, so it can check if it is allowed to execute effects ot not.

The vibra control register will be used from the ASoC codec driver as well. In order to avoid latency issues caused by I2C read access, cache the two control register within the core driver, so we do not need to reach out to the chip to read it back.

2011-10-09ASoC: Cache connected input and output recursionsMark Brown1-0/+2
The number of connected input and output endpoints for a given widgets can't change during a DAPM run so there is no need to redo the recursion through branches of the tree we've already visited. Doing this on one of my test systems gives an improvement of: Power Path Neighbour Before: 63 607 731 After: 63 141 181 which scales up well as more widgets are involved in paths.

2011-10-05ASoC: core: Change SOC_SINGLE/DOUBLE_VALUE representationPeter Ujfalusi1-2/+15
SOC_SINGLE/DOUBLE_VALUE is used for mixer controls, where the bits are within one register. Assign .rreg to be the same as .reg for these types. With this change we can tell if the mixer in question: is mono: mc->reg == mc->rreg && mc->shift == mc->rshift is stereo, within single register: mc->reg == mc->rreg && mc->shift != mc->rshift is stereo, in two registers: mc->reg != mc->rreg The patch provide a small inline function to query, if the mixer is stereo, or mono.

2011-10-05ASoC: Only run power_check() on a widget once per runMark Brown1-0/+2
Some widgets will get power_check() run on them more than once during a DAPM run, most commonly due to supply widgets checking to see if their consumers are powered up. It's wasteful to do this so cache the result of power_check() during a run. For one system I tested this on I got an improvement of: Power Path Neighbour Before: 106 970 1186 After: 69 727 905 from this. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2011-10-04ASoC: Do DAPM power checks only for widgets changed since last runMark Brown2-0/+2
In order to reduce the number of DAPM power checks we run keep a list of widgets which have been changed since the last DAPM run and iterate over that rather than the full widget list. Whenever we change the power state for a widget we add all the source and sink widgets it has to the dirty list, ensuring that all widgets in the path are checked. This covers more widgets than we need to as some of the neighbour widgets won't be connected but it's simpler as a first step. On one system I tried this gave: Power Path Neighbour Before: 207 1939 2461 After: 114 1066 1327 which seems useful. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2011-09-28ASoC: Allow DAI formats to be specified in the dai_linkMark Brown2-17/+19
For almost all machines the DAI format is a constant, always set to the same thing. This means that not only should we normally set it on init rather than in hw_params() (where it has been for historical reasons) we should also allow users to configure this by setting a variable in the dai_link structure. The combination of these two will make many machine drivers even more data driven. Implement a new dai_fmt field in the dai_link doing just that. Since 0 is a valid value for many format flags and we need to be able to tell if the field is actually set also add one to all the values used to configure formats.

2011-09-21ASoC: Trace and collect statistics for DAPM graph walkingMark Brown3-0/+28
One of the longest standing areas for improvement in ASoC has been the DAPM algorithm - it repeats the same checks many times whenever it is run and makes no effort to limit the areas of the graph it checks meaning we do an awful lot of walks over the full graph. This has never mattered too much as the size of the graph has generally been small in relation to the size of the devices supported and the speed of CPUs but it is annoying. In preparation for work on improving this insert a trace point after the graph walk has been done. This gives us specific timing information for the walk, and in order to give quantifiable (non-benchmark) numbers also count every time we check a link or check the power for a widget and report those numbers. Substantial changes in the algorithm may require tweaks to the stats but they should be useful for simpler things. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

There is no need to write to the vio registers at probe time, since most them either read only, or shared with MFD or not used. On the other hand it is a good idea to updated the ASICREV register in the cache at this time. After power up we need to restore some registers.

2011-09-14regulator: Implement deferred disable supportMark Brown2-0/+10
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().

2011-08-31ASoC: Allow source specification for CODEC level sysclkMark Brown1-2/+2
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>

2011-08-21regmap: Allow drivers to specify register defaultsMark Brown1-2/+22
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.

Some devices are sensitive to reads on their registers, especially for things like clear on read interrupt status registers.

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.
