2013-10-25Merge tag 'asoc-v3.13' of ↵Takashi Iwai1-62/+109
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next ASoC: Updates for v3.13 - Further work on the dmaengine helpers, including support for configuring the parameters for DMA by reading the capabilities of the DMA controller which removes some guesswork and magic numbers fromm drivers. - A refresh of the documentation. - Conversions of many drivers to direct regmap API usage in order to allow the ASoC level register I/O code to be removed, this will hopefully be completed by v3.14. - Support for using async register I/O in DAPM, reducing the time taken to implement power transitions on systems that support it.

These aren't necessary after switch and if blocks. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-10-03ASoC: tas5086: add suspend callbackDaniel Mack1-2/+28
When going to suspend, shut down all channels and re-do the init procedure at resume time. Signed-off-by: Daniel Mack <zonque@gmail.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2013-10-03ASoC: tas5086: move initialization code to own functionsDaniel Mack1-56/+72
We'll need to call code to initialize and reset the codec again at resume time, so factor it out first. Signed-off-by: Daniel Mack <zonque@gmail.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2013-10-03ASoC: tas5086: move two variables into private structDaniel Mack1-9/+13
We need to access the charge_period and start_mid_z values from other places later, so move them to the private struct. Signed-off-by: Daniel Mack <zonque@gmail.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2013-06-28ASoC: tas5086: fix Mid-Z implementationDaniel Mack1-6/+9
It turns out that the TAS5086 doesn't like channel start parts to be empty, and if all channels are configured to Mid-Z, part 1 has to be used. Signed-off-by: Daniel Mack <zonque@gmail.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2013-06-28ASoC: tas5086: fix TAS5086_CLOCK_CONTROL register sizeDaniel Mack1-1/+1
The TAS5086_CLOCK_CONTROL also has a size of 1 byte. Signed-off-by: Daniel Mack <zonque@gmail.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2013-06-25ASoC: tas5086: add support for pwm start mode configDaniel Mack1-0/+22
The TAS5086 has two alternative modes to start its PWM channels, Mid-Z and Low-Z. Which one to use depends on how the PWM power stages are connected to the TAS5086. This patch adds 6 optional boolean properties to the DT bindings of the driver which allow the user to configure each individual channel to the Mid-Z scheme, and leaves all the others to the default (Low-Z).

2013-06-25ASoC: tas5086: add DAPM mux controlsDaniel Mack1-0/+200
The TAS5086 has two muxes, one for connecting I2S inputs to internal channels, and another one for selecting which internal channel should be routed to which PWM output pin. This patch adds DAPM widgets and routes for this driver. Signed-off-by: Daniel Mack <zonque@gmail.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2013-06-25ASoC: tas5086: add more register definesDaniel Mack1-3/+17
Add register definitions for input and output mux registers, and rewrite the tas5086_accessible_reg() function. Signed-off-by: Daniel Mack <zonque@gmail.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2013-06-25ASoC: tas5086: open-code I2C transfer routinesDaniel Mack1-1/+84
In order to support registers of unequal sizes, the I2C I/O has to be open-coded. Signed-off-by: Daniel Mack <zonque@gmail.com> Signed-off-by: Mark Brown <broonie@linaro.org>

2013-03-12ASoC: tas5086: use module_i2c_driver to simplify the codeWei Yongjun1-11/+1
Use the module_i2c_driver() macro to make the code smaller and a bit simpler. Signed-off-by: Wei Yongjun <yongjun_wei@trendmicro.com.cn> Acked-by: Daniel Mack <zonque@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2013-03-08ALSA: ASoC: add codec driver for TI TAS5086Daniel Mack1-0/+601
This patch adds a driver for TI's TA5086 6-channel PWM processor. This chip has a very unusual register layout, specifically because the registers are of unequal size, and multi-byte registers require bulk writes to take effect. Regmap does not support these kind of mappings. Currently, the driver does not touch any of the registers >= 0x20, so it doesn't matter, because the register map is mapped to an 8-bit array. In case more features will be added in the future that require access to higher registers, the entire regmap H/W I/O routines have to be open-coded.
