2016-06-15ASoC: adau17x1: Add support for specifying the MCLK using the CCFLars-Peter Clausen1-1/+1
The devices from the ADAU17X1 family all have a MCLK clock input which supplies the master clock for the device. The master clock is used as the input clock for the PLL. Currently the MCLK rate as well as the desired PLL output frequency need to be supplied by calling snd_soc_dai_set_pll() form a machine driver. Add support for specifying the MCLK using the common clock framework. In addition to that also automatically configure the PLL to a suitable rate if the master clock was provided using the CCW. This allows to use the CODEC driver without any special configuration requirements from the machine driver. While the PLL output frequency can be configured over a (more or less) continuous range the narrowness of the range and the other constraints of the clocking tree usually only result in two output frequencies that will actually be chosen. One for 44.1kHz based rates and one for 48kHz based rates, these are the rates that the automatic PLL configuration will use. For the rare case where a non-standard setup is required a machine driver can disable the auto-configuration and configure a custom frequency using the existing mechanisms. If the common clock framework is not enabled clk_get() will return NULL and the driver will function as before and the clock rate needs to be configured manually.

i2c_driver does not need to set an owner because i2c_register_driver() will set it. Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-05-27ASoC: Add ADAU1361/ADAU1761 audio CODEC supportLars-Peter Clausen1-0/+60
This patch adds support for the Analog Devices ADAU1361 and ADAU1761 CODECs. The device is a a low-power, 24-bit stereo audio CODEC with multiple analog input and outputs, one digital microphone input and an I2S interface. The device can be controlled either via I2C or SPI. The main difference between the two variants is that the ADAU1761 has a built-in SigmaDSP, while the ADAU1361 has not.
