This patch series aims to add ASoC support on RZ/G2L SoC's.
It is based on the work done by Chris Brandt for RZ/A ASoC driver.
v4->v5 * Moved validation of sample bits in hw_params * Removed validation of frame bits as it is redundant * split the rz_ssi_start_stop function into rz_ssi_start and rz_ssi_stop. * remove the spin_lock around rz_ssi_stream_init. * Updated dmas description and removed fixes as it is an enhancement now. * updated ssi_start functions with setting fifo thresholds and ssi_stop function with cancel all dma txn. v3->v4: * Updated the subject line as per style for the subsystem. * Removed select SND_SIMPLE_CARD from Kconfig * Added C++ comments for copyright and driver description. * Moved validation of channels in hw_params * removed asm issue reported by bot as well as Mark * replaced master/slave macros with provider/consumer macros * Improved locking and added more null pointer checks. v2->v3: * Fixed the dependency on KCONFIG * Merged the binding patch with dma feature added * Updated dt binding example with encoded #dma-cells value. * Improved Error handling in probe function * Removed the passing legacy channel configuration parameters from dmaengine_slave_config function * started using dma_request_chan instead of deprecated dma_request_slave_channel * Removed SoC dtsi and config patches from this series. Will send it later. v1->v2: * Rebased to latest rc kernel
