Guennadi Liakhovetski 1ff8df4f53 dma: sh: provide a migration path for slave drivers to stop using .private ... This patch extends the sh dmaengine driver to support the preferred channel selection and configuration method, instead of using the "private" field from struct dma_chan. We add a standard filter function to be used by slave drivers instead of implementing their own ones, and add support for the DMA_SLAVE_CONFIG control operation, which must accompany the new channel selection method. We still support the legacy .private channel allocation method to cater for a smooth driver migration.
