[PATCH 0/4] RK3588 Audio Support
This patchset refactors the Rockchip I2S/TDM driver in order to support the RK3588 SoC, and then adds the necessary compatible string to load the driver for it.
Patch 1 rectifies a problem with the bindings where we were too strict about requiring the rockchip,grf property. Most features of this audio device don't need access to the GRF to function.
Patch 2 modifies the driver to adjust its behaviour to what the changed bindings now allow, namely using most things without the GRF.
Patch 3 and 4 are boring compatible string stuff that enables RK3588 support. No special data is needed to initialise the driver for this instance of the I2S/TDM IP.

Turns out most things don't require the GRF, so making the property optional is the obvious move.

Only IO Multiplex and two TRCM modes need access to the GRF, so making it a hard requirement is not a wise idea, as it complicates support for newer SoCs which do not do these things.

This adds the compatible string for the RK3588 SoC.

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
