The external mute (if it is in use) is handled by a GPIO line. Prepare to remove the set_hs_extmute callback and replace it with: hs_extmute_gpio: the GPIO number to use for external mute When the users of set_hs_extmute has been converted the callback can be removed. Signed-off-by:

Instead of the OMAP DMA data type definition the data_type will be used to specify the number of bits the DMA word should be configured or 0 in case when based on the stream's format the omap-pcm can decide the needed DMA word size. This feature is needed for the omap-hdmi where the sDMA need to be configured for 32bit word type regardless of the audio format used. Signed-off-by:

Based on the format of the stream the omap-pcm can decide alone what data type should be used with by the sDMA. Keep the possibility for OMAP dai drivers to tell omap-pcm if they want to use different data type. This is needed for the omap-hdmi for example which needs 32bit data type even if the stream format is S16_LE. The check if (dma_data->data_type) is safe at the moment since omap-pcm does not support 8bit samples (OMAP_DMA_DATA_TYPE_S8 == 0x00). The next step is to redefine the meaning of dma_data->data_type to unblock this limitation. Signed-off-by:

The omap-pcm platform driver no longer needs this parameter to select between ELEMENT and PACKET mode. The selection is based on the configured packet_size. Signed-off-by:

Peter Ujfalusi authored
Since we only have element or packet synchronization we can use the dma_data->packet_size to select the desired mode: if packet_size is 0 we use ELEMENT mode if packet_size is not 0 we use PACKET mode for sDMA synchronization. Signed-off-by:

The audio stack used omap_stop_dma/omap_start_dma to pause/resume the DMA. This method has been used for years on OMAP based products. We only allow pause/resume when the DMA has been configured in cyclic mode which is used by the audio stack. Signed-off-by:

The 'dres' field (discharge resistance for headphone outputs) is no longer used in the driver, so remove it. It was used in the original version of the driver when entering standby from off, but we stopped using it when we switched from having a single startup sequence to having separate cap and capless sequences.

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:
