Hi Martin,

The UFS controller in the Google Pixel 6 and 7 phones 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 and 7. Please consider
these patches for the next merge window.

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

Thanks,

Bart.
