[PATCH v2 00/10] ASoC: rockchip: spdif: Cleanups and port features from Rockchip's BSP kernel

Posted by Sebastian Reichel 3 days, 12 hours ago

I'm currently working on DisplayPort audio support for the Rockchip
RK3588/RK3576 SoCs, which preferrably use S/PDIF as DAI source.

Apparently the upstream Rockchip S/PDIF driver is lacking a couple of
features right now, which are necessary to get things going (i.e.
setting the sysclk from the machine driver). I found the missing bits
in Rockchip's 6.1 BSP kernel and ported them over. This series effectly
brings the mainline kernel on-par with the BSP driver, but also contains
a couple of cleanup patches of my own to bring the driver to the modern
age.

Changes in v2:
- Link to v1: https://lore.kernel.org/r/20260127-rockchip-spdif-cleanup-and-bsp-sync-v1-0-a7c547072bbb@collabora.com
- Fix missing return in dev_err_probe() patch (Alexey Charkov)
- Fix commit message in sample rate support patch (Mark Brown)
- Fix missing bitfield include in FIELD_PREP patch (kernel test robot)

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
