These things are defined to be used by some UFS Host controllers. And a new file for some declarations of mphy standard is added V2 - modify the commit message - add a new macro for UECDL - add two definitions about UECDL - change the names of two macros (s/IS_PWR_MODE_HS/IS_HS_PWR_MODE, s/IS_PWR_MODE_PWM/IS_PWM_PWR_MODE) Signed-off-by: Kiwoong Kim <kwmad.kim@xxxxxxxxxxx> --- drivers/scsi/ufs/mphy.h | 38 ++++++++++++++++++++++++++++++++++++++ drivers/scsi/ufs/ufshci.h | 17 ++++++++++++++--- drivers/scsi/ufs/unipro.h | 26 ++++++++++++++++++++++++++ 3 files changed, 78 insertions(+), 3 deletions(-) create mode 100644 drivers/scsi/ufs/mphy.h diff --git a/drivers/scsi/ufs/mphy.h b/drivers/scsi/ufs/mphy.h new file mode 100644 index 0000000..c431f49 --- /dev/null +++ b/drivers/scsi/ufs/mphy.h @@ -0,0 +1,38 @@ +/* + * drivers/scsi/ufs/mphy.h + * + * Copyright (C) 2014 Samsung Electronics Co., Ltd. + * + * This program is free software;
