| | * | ASoC: dapm: Allow regulators to bypass as well as disable when idleMark Brown2012-09-261-2/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow regulators managed via DAPM to make use of the bypass support that has recently been added to the regulator API by setting a flag SND_SOC_DAPM_REGULATOR_BYPASS. When this flag is set the regulator will be put into bypass mode before being disabled, allowing the regulator to fall into bypass mode if it can't be disabled due to other users.

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.
