The first 3 patches are for supporting ufshcd_abort(). The 4th and 5th patches are for supporting error handler. Bao D. Nguyen (5): ufs: mcq: Add supporting functions for mcq abort ufs: mcq: Add support for clean up mcq resources ufs: mcq: Added ufshcd_mcq_abort() ufs: mcq: Use ufshcd_mcq_poll_cqe_lock() in mcq mode ufs: core: Add error handling for MCQ mode Reviewed-by: Stanley Chu Reviewed-by: Po-Wen Kao --- v1->v2: patch #1: Addressed Powen's comment. Replaced read_poll_timeout() with ufshcd_mcq_poll_register(). The function read_poll_timeout() may sleep while the caller is holding a spin_lock(). Poll the registers in a tight loop instead. --- drivers/ufs/core/ufs-mcq.c | 258 ++++++++++++++++++++++++++++++++++++++++- drivers/ufs/core/ufshcd-priv.h | 15 ++- drivers/ufs/core/ufshcd.c | 140 ++++++++++++++++++---- drivers/ufs/host/ufs-qcom.c | 2 +- include/ufs/ufshcd.h | 2 +- include/ufs/ufshci.h | 17 +++ 6 files changed, 404 insertions(+), 30 deletions(-)
