Daniel Mack 13b3006b8e dma: mmp_pdma: add filter function ... PXA peripherals need to obtain specific DMA request ids which will eventually be stored in the DRCMR register. Currently, clients are expected to store that number inside the slave config block as slave_id, which is unfortunately incompatible with the way DMA resources are handled in DT environments. This patch adds a filter function which stores the filter parameter passed in by of-dma.c into the channel's drcmr register. For backward compatability, cfg->slave_id is still used if set to a non-zero value.
