This is more idiomatic as it means we verify that the device is there prior to trying to do the card probe. Signed-off-by:Mark Brown <broonie@opensource.wolfsonmicro.com>

If the LRCLK is shared and the WM8960 is clock master then we should enable the LRCM bit to tell the device that it should drive LRCLK when either ADC or DAC is enabled rather than separately driving the two LRCLKs. Signed-off-by: -

When audmux_read_file is called, it means the driver is already initialised successfully, so we don't need to check audmux_base. It also fix smatch warning: sound/soc/fsl/imx-audmux.c:78 audmux_read_file() warn: possible memory leak of 'buf' Signed-off-by:

For ENUM controls the bitmask is calculated based on the number of items. Currently this is done each time the control is accessed. And while the performance impact of this should be negligible we can easily do better. The roundup_pow_of_two macro performs the same calculation which is currently done manually, but it is also possible to use this macro with compile time constants and so it can be used to initialize static data. So we can use it to initialize the mask field of a ENUM control during its declaration. Signed-off-by:

PowerPC ASoC drivers frequently use the _BE variants of the SNDRV_PCM_FORMAT macros, so we need to look for those as well. Signed-off-by:

Remove a call to dma_unmap_single() from the PowerPC ASoC DMA driver. The buffer is allocated and not actually mapped, so the unmap call doesn't make sense. It was probably left over from some early version of the driver. This bug was unnoticed for so long because the DMA mapping functions normally don't do anything on PowerPC. Signed-off-by:

Use snd_soc_register_card() instead of platform_device_alloc("soc-audio") to register the sound card from the machine drivers. The use of platform_device_alloc is deprecated. Although several other drivers still use platform_device_alloc(), the Freescale drivers were not using it to pass driver data. Instead of fixing the driver data usage, it's better to replace the deprecated code. Signed-off-by:

Rather than including mach/iomux-mx27.h to define gpio numbers and set up the pins, the patch moves all these into machine code and has the gpio numbers passed to driver via platform_data. As the result, we can remove the mach/iomux-mx27.h inclusion from driver. Signed-off-by:

The core has for a long time had support for marking the register maps of devices dirty when suspending so that they are resynced on resume. Also implement this feature for CODECs using regmap. Signed-off-by:
