[SCSI] ufshcd: UFS Host controller driver
This patch adds support for Universal Flash Storage(UFS)
host controllers. The UFS host controller driver
includes host controller initialization method.
The Initialization process involves following steps:
- Initiate UFS Host Controller initialization process by writing
to Host controller enable register
- Configure UFS Host controller registers with host memory space
datastructure offsets.
- Unipro link startup procedure
- Check for connected device
- Configure UFS host controller to process requests
- Enable required interrupts
- Configure interrupt aggregation
