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

From: Stanley Chu
Date: Wed Mar 18 2020 - 06:40:49 EST


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
