From b294ff3e34490f36233230e9ca70503d3924a6f3 Mon Sep 17 00:00:00 2001 From: Asutosh Das Date: Fri, 23 Apr 2021 17:20:16 -0700 Subject: scsi: ufs: core: Enable power management for wlun During runtime-suspend of ufs host, the SCSI devices are already suspended and so are the queues associated with them. However, the ufs host sends SSU (START_STOP_UNIT) to the wlun during runtime-suspend. During the process blk_queue_enter() checks if the queue is not in suspended state. If so, it waits for the queue to resume, and never comes out of it. Commit 52abca64fd94 ("scsi: block: Do not accept any requests while suspended") adds the check to see if the queue is in suspended state in blk_queue_enter().

Also make this a supplier for all other LUNs. This way the wlun device suspends after all the consumers and resumes after HBA resumes. This also registers a new SCSI driver for rpmb wlun. This new driver is mostly used to clear rpmb uac.
