Merge tag 'soundwire-5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vkoul/soundwire into char-misc-next
Vinod writes:
soundwire updates for 5.10-rc1
This round of update includes:
- Generic bandwidth allocation algorithm from Intel folks
- PM support for Intel chipsets
- Updates to Intel drivers which makes sdw usable on latest laptops
- Support for MMIO SDW controllers found in QC chipsets
- Update to subsystem to use helpers in bitfield.h to manage register
bits
