Hi Martin,

The UFS controller in the Google Pixel 6 phone requires that SCSI command
processing is suspended while reprogramming encryption keys. The patches in
this series are a first step towards integrating support in the upstream
kernel for the UFS controller in the Pixel 6. Please consider these patches
for inclusion in kernel v5.19.

Note: instructions for downloading the Pixel 6 source code are available at
https://source.android.com/setup/build/building-kernels.

Thanks,

Bart.

Bart Van Assche (4):
  scsi: ufs: Reduce the clock scaling latency
  scsi: ufs: Move a clock scaling check
  scsi: ufs: Pass the clock scaling timeout as an argument
  scsi: ufs: Add suspend/resume SCSI command processing support
