This series is a preparatory cleanup of the jz4740-i2s driver before adding support for a new SoC. The two improvements are lifting unnecessary restrictions on sample rates and formats -- the existing ones appear to be derived from the limitations of the JZ4740's internal codec and don't reflect the actual capabilities of the I2S controller.
I'm unable to test the series on any JZ47xx SoCs, but I have tested on an X1000 (which is the SoC I'll be adding in a followup series).
Changes in v6:
* Added Cc: stable for flush bits fix.
Changes in v5:
* Drop 'mem' resource removal patch already upstream. * Update FIFO flush bits fix to address Paul's review comments. * Drop PLL clock name patch, that needs a different approach.
