[v2,0/11] ASoC: cleanups and improvements for jz4740-i2s

Message

Aidan MacDonald July 7, 2022, 7:46 p.m. UTC

This series is a preparatory cleanup of the jz4740-i2s driver before
adding support for a new SoC. The last two patches lift 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 v2:

* Drop two patches already in sound for-next.
* Squash two removal patches into the regmap fields patch.
* Remove the unused 'mem' resource in the driver private struct.
* Use regmap_set_bits() and regmap_clear_bits() to improve readability.
* Add fix for SoCs with independent FIFO flush bits (ie. most of them).
* Update sample formats patch with a more informative commit message.
* Add two new patches to refactor DAI/component probing.
