From: Bean Huo <beanhuo@micron.com> Changelog: v6--v7: 1. Change wb_on sysfs documentation and add information that WriteBooster is already enabled after power-on/reset(Incorporate Adrian Hunter's suggestion) v5--v6: 1. Remove original patch 7/7: "scsi: ufs: Keep device active mode only fWriteBoosterBufferFlushDuringHibernate == 1" 2. Rebased patch onto 5.12/scsi-staging 3. Add protection of PM ops and err_handler for the wb_on entry access V4--V5: 1. Add patch "docs: ABI: Add wb_on documentation for UFS sysfs" 2. Unify WB related flags with wb_* prefix (Stanley Chu) 3. Delete d_ext_ufs_feature_sup (Stanley Chu) 4. Incorporate Stanley's suggestion to patch 6/7 5. Replace scnprintf() with sysfs_emit() in 1/7 (Greg KH) v3--v4: 1. Rebase patch on 5.11/scsi-staging 2. Add WB cleanup patches 3/6, 4/6 adn 5/6 v2--v3: 1. Change multi-line comments style in patch 1/3 (Can Guo) v1--v2: 1. Take is_hibern8_wb_flush checkup out from function ufshcd_wb_need_flush() in patch 2/3 2. Add UFSHCD_CAP_CLK_SCALING checkup in patch 1/3. that means only for the platform, which doesn't support UFSHCD_CAP_CLK_SCALING, can control WB through "wb_on".
