Subject: ASoC: omap-pcm, omap-dmic: Change the use of omap_pcm_dma_data->data_type
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f05cc9dac99ac6403d057d2cccb3c754714d2f32;p=linux-beck.git

ASoC: omap-pcm, omap-dmic: Change the use of omap_pcm_dma_data->data_type

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.
