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

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)
