[PATCH v3 0/14] Patches to update for rockchip i2s
These patches fixup or update for rockchip i2s.
Changes in v3: - Drop property 'rockchip,playback-only', 'rockchip,capture-only'. Implement it by 'dma-names' of DT instead.
Changes in v2: - split property trcm into single 'trcm-sync-tx-only' and 'trcm-sync-rx-only' suggested by Nicolas. - split property trcm into single 'trcm-sync-tx-only' and 'trcm-sync-rx-only' suggested by Nicolas. - drop change-id

MCLK maybe not precise as required because of PLL, but which still can be used and no side effect. so, using DIV_ROUND_CLOSEST instead div.
e.g.
set mclk to 11289600 Hz, but get 11289598 Hz.

API 'set_fmt' maybe called when PD is off, in the situation, any register access will hang the system. so, enable PD before r/w register.

This patch documents property 'rockchip,trcm-sync-tx-only/rx-only' which is used to specify the lrck.

Why is this a global and not part of the driver data? It's also not clear to me why this is a spinlock and not a mutex.

These patches fixup or update for rockchip i2s.
Changes in v3:
- Drop property 'rockchip,playback-only', 'rockchip,capture-only'. Implement it by 'dma-names' of DT instead.
Changes in v2:
- split property trcm into single 'trcm-sync-tx-only' and 'trcm-sync-rx-only' suggested by Nicolas.
- split property trcm into single 'trcm-sync-tx-only' and 'trcm-sync-rx-only' suggested by Nicolas.

All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
Thanks, Mark

Yes, this should be moved into driver data, will do in v4.
it's not allowed to sleep in this context, so use spinlock instead.
