* ASoC: Fix wrong data type access in a few codec driversJarkko Nikula2011-05-165-7/+12
| | | | | | | | | | | | | Commit fafd217 ("ASoC: Store a list of widgets in a DAPM mux/mixer kcontrol") changed the control private data type that is passed to snd_soc_cnew when creating dapm mixer and mux controls. Commit did not update a few codec drivers that are using their own put callbacks and thus are accessing a wrong data type.

* ASoC: Use spi_write() for SPI writesMark Brown2011-05-111-128/+4
| | | | | | | | | | | | | do_spi_write() is just an open coded copy of do_spi_write() so we can delete it and just call spi_write() directly. Indeed, as a result of recent refactoring all the SPI write functions are just very long wrappers around spi_write() which don't add anything except for some pointless copies so we can just use spi_write() as the hw_write operation directly. It should be as type safe to do this as it is to do the same thing with I2C and it saves us a bunch of code.

* ASoC: Remove byte swap in 4x12 SPI writeMark Brown2011-05-111-6/+5
| | | | | | | | | | | | | | snd_soc_4_12_spi_write() contains a byte swap. Since this code was written for an Analog CODEC on a Blackfin reference board it appears that this is done because while Blackfin is little endian the CODEC is big endian (as are most CODECs). Push this up into the generic 4x12 write function and use cpu_to_be16() to do the byte swap so things are more regular and things work on both CPU endiannesses.

Specifically: static const struct snd_kcontrol_new adcinput_mux = SOC_DAPM_ENUM("ADC Input", adcinput_enum); static const struct snd_soc_dapm_widget wm8903_dapm_widgets[] = { SND_SOC_DAPM_MUX("Left ADC Input", SND_SOC_NOPM, 0, 0, &adcinput_mux), SND_SOC_DAPM_MUX("Right ADC Input", SND_SOC_NOPM, 0, 0, &adcinput_mux), }; This is useful when a single register bit or field affects multiple muxes at once. The common case is to have separate control bits or fields for each mux (channel). An alternative way of looking at this is that the mux is a stereo (or even n-channel) mux, rather than independant mono muxes. Without this change, a separate kcontrol will be created for each DAPM_MUX. This has the following disadvantages: * Confuses the user/programmer with redundant controls that don't map to separate hardware. * When one of the controls is changed, ASoC fails to update the DAPM logic for paths solely affected by the other controls impacted by the same register bits. This causes some paths not to be correctly powered up or down. Prior to this change, to work around this, the user or programmer had to manually toggle all duplicate controls away from the intended setting, and then back to it. Control sharing implies that the control is named based on the kcontrol_new itself, not any of the widgets that are affected by it. Control sharing is implemented by: When creating kcontrols, if a kcontrol does not yet exist for a particular kcontrol_new, then a new kcontrol is created with a list of widgets containing just a single entry. This is the normal case. However, if a kcontrol does already exists for the given kcontrol_new, the current widget is simply added to that kcontrol's list of affected widgets.

For example, a single register bit that controls separate muxes in both the L and R audio paths. This change updates the code that handles relevant controls to be able to iterate over a list of affected widgets. Note that only the put functions need significant modification to implement the iteration; the get functions do not need to iterate, nor unify the results, since all affected widgets reference the same kcontrol. When creating the list of widgets, always create a 1-sized list, since the control sharing is not implemented in this change.
