Additionally, Samsung UFS devices require extra time in hibern8 mode before exiting, beyond the standard handshaking phase between the host and device. Introduce a quirk to increase the PA_HIBERN8TIME parameter by 100 µs to ensure a proper hibernation process. --- Changes in V2 - Split patches to add PA_HIBERN8TIME quirk in ufshcd.c --- Manish Pandey (2): ufs: qcom: Add quirks for Samsung UFS devices scsi: ufs: introduce quirk to extend PA_HIBERN8TIME for UFS devices drivers/ufs/core/ufshcd.c | 31 ++++++++++++++++++++++++++ drivers/ufs/host/ufs-qcom.c | 43 +++++++++++++++++++++++++++++++++++++ drivers/ufs/host/ufs-qcom.h | 18 ++++++++++++++++ include/ufs/ufs_quirks.h | 6 ++++++ 4 files changed, 98 insertions(+)
