Subject: [PATCH v7 0/7] scsi: ufs: some cleanups and make the delay for host enabling customizable

v6 -> v7
	- Fix patch #3 "scsi: ufs: introduce common delay function" (Bart Van Assche)
		- Remove "can_sleep" related changes.
		- Limit the usage of common delay function, for example, if delay time
		is fixed and larger than 10 us, using introduced common delay function is not required.
	- Other related changes according to patch #3 changes

v5 -> v6
	- Drop patch #2 "scsi: ufs: remove init_prefetch_data in struct ufs_hba" in v5
	because Can Guo has similar cleanup earlier in patch "scsi: ufs: Do not rely on prefetched data"

v4 -> v5
	- Fix patch #7: Fix typo "initializatoin" in title

v3 -> v4
	- In patch #8, fix incorrect condition of customized delay for host enabling

v2 -> v3
	- Remove /arch/arm64/configs/defconfig chnage because it is for local test only

v1 -> v2
	- Add patch #1 "scsi: ufs: fix uninitialized tx_lanes in ufshcd_disable_tx_lcc"
	- Remove struct ufs_init_prefetch in patch #2 "scsi: ufs: remove init_prefetch_data in struct ufs_hba"
	- Introduce common delay function in patch #4
	- Replace all delay places by common delay function in ufs-mediatek in patch #5
	- Use common delay function instead for host enabling delay in patch #6
	- Add patch #7 "scsi: ufs: make HCE polling more compact to improve initializatoin latency"
	- In patch #8, customize the delay in ufs_mtk_hce_enable_notify callback instead of ufs_mtk_init (Avri Altman)

Stanley Chu (7):
  scsi: ufs: fix uninitialized tx_lanes in ufshcd_disable_tx_lcc()
  scsi: ufs: use an enum for host capabilities
  scsi: ufs: introduce common and flexible delay function
  scsi: ufs-mediatek: use common delay function for required places
  scsi: ufs: allow customized delay for host enabling
  scsi: ufs: make HCE polling more compact to improve initialization
    latency
  scsi: ufs-mediatek: customize the delay for host enabling
