2015-08-05ASoC: ssm2602: Replace TLV_DB_RANGE_HEAD with DECLARE_TLV_DB_RANGELars-Peter Clausen1-4/+3
DECLARE_TLV_DB_RANGE() has the advantage over using TLV_DB_RANGE_HEAD() that it automatically calculates the number of items in the TLV and is hence less prone to manual error.

2014-09-04ASoC: ssm2602: Cleanup manual bias level transitionsLars-Peter Clausen1-22/+2
Set the CODEC driver's suspend_bias_off flag rather than manually going to SND_SOC_BIAS_OFF in suspend and SND_SOC_BIAS_STANDBY in resume. This makes the code a bit shorter and cleaner. While we are at it also remove the regcache_cache_only() calls from suspend/resume as there shouldn't be any IO between suspend and resume. Since the ASoC core now takes care of setting the bias level to SND_SOC_BIAS_OFF when removing the CODEC there is no need to do it manually anymore either. The manual transition to SND_SOC_BIAS_STANDBY at the end of CODEC probe() can also be removed as the core will automatically do this after the CODEC has been probed.

2014-02-18ASoC: ssm2602: Split SPI and I2C code into different modulesLars-Peter Clausen1-138/+20
There are a few known (minor) problems with having the support code for both I2C and SPI in the same module: * We need to be extra careful to make sure to not build the driver into the kernel if one of the subsystems is build as a module (Currently only I2C can be build as a module). * The module init path error handling is rather ugly. E.g. what should be done if either the SPI or the I2C driver fails to register? Most drivers that implement SPI and I2C in the same module currently fallback to undefined behavior in that case. Splitting the the driver into two modules, one for each bus allows the registration of the other bus driver to continue without problems if one of them fails. This patch splits the ssm2602 driver into 3 modules. One core module that implements the device logic, but is independent of the bus method used. And one module for SPI and I2C each that registers the drivers and sets up the regmap struct for the bus. While we are at it also cleanup the include section of the ssm2602 driver and remove unneeded includes.

2012-04-04ASoC: codecs: Remove rtd->codec usage from CODEC driversMark Brown1-6/+3
In order to support CODEC<->CODEC links remove the assumption that there is only a single CODEC on a DAI link by removing the use of the CODEC pointer in the rtd from the CODEC drivers. They are already being passed their DAI whenever they are passed an rtd and can get the CODEC from there. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-02-04ASoC: core: Add support for DAI and machine kcontrols.Liam Girdwood1-1/+1
Currently ASoC can only add kcontrols using codec and platform component device handles. It's also desirable to add kcontrols for DAIs (i.e. McBSP) and for SoC card machine drivers too. This allows the kcontrol to have a direct handle to the parent ASoC component DAI/SoC Card/Platform/Codec device and hence easily get it's private data. This change makes snd_soc_add_controls() static and wraps it in the folowing calls (card and dai are new) :- snd_soc_add_card_controls() snd_soc_add_codec_controls() snd_soc_add_dai_controls() snd_soc_add_platform_controls() This patch also does a lot of small mechanical changes in individual codec drivers to replace snd_soc_add_controls() with snd_soc_add_codec_controls(). It also updates the McBSP DAI driver to use snd_soc_add_dai_controls(). Finally, it updates the existing machine drivers that register controls to either :- 1) Use snd_soc_add_card_controls() where no direct codec control is required. 2) Use snd_soc_add_codec_controls() where there is direct codec control. In the case of 1) above we also update the machine drivers to get the correct component data pointers from the kcontrol (rather than getting the machine pointer via the codec pointer).

2011-11-23ASoC: Constify snd_soc_dai_ops structsLars-Peter Clausen1-1/+1
Commit 1ee46ebd("ASoC: Make the DAI ops constant in the DAI structure") introduced the possibility to have constant DAI ops structures, yet this is barley used in both existing drivers and also new drivers being submitted, although none of them modifies its DAI ops structure. The later is not surprising since existing drivers are often used as templates for new drivers. So this patch just constifies all existing snd_soc_dai_ops structs to eliminate the issue altogether.

2011-09-27ASoC: ssm2602: Support setting the oscillator and the clock output stateLars-Peter Clausen1-16/+51
Currently the oscillator is always enabled and the clock output is always disabled. This patch adds support for controlling the oscillator and clock output state through snd_soc_dai_set_sysclk. Which makes it possible to disable or enable them dynamically according to the requirements of the board on which the CODEC is used. This patch also slightly modifies the behavior as to when the oscillator is going to be disabled in low-power states. Previously it would only be disabled in BIAS_OFF, now it is also going to be disabled in BIAS_STANDBY, since no components which depend on it should be active in this state.

2011-09-27ASoC: ssm2602: Re-enable oscillator after suspendLars-Peter Clausen1-1/+2
Currently the the internal oscillator is powered down when entering BIAS_OFF state, but not re-enabled when going back to BIAS_STANDBY. As a result the CODEC will stop working after suspend if the internal oscillator is used to generate the sysclock signal. This patch fixes it by clearing the appropriate bit in the power down register when the CODEC is re-enabled.
