[PATCH v2 0/2] ufs-qcom: Reduce interrupt latency

[Bart Van Assche <bvanassche@acm.org>]

Hi Martin,

On Android systems it is important to keep the time spent in interrupts short.
This keeps the user interface responsive and prevents audio stuttering. Hence
this patch series to reduce the time spent in the UFS interrupt handler. Please
consider this patch series for the next merge window after test results have
been shared by Qualcomm.

Thanks,

Bart.

Changes compared to v1:
 - Dropped the ufshcd_mcq_compl_all_cqes_lock() changes.
 - Renamed ufshcd_mcq_poll_cqe_lock_n() into ufshcd_mcq_poll_n_cqe_lock().

  ufs: core: Introduce ufshcd_mcq_poll_n_cqe_lock()
  ufs: qcom: Reduce interrupt latency
