From 24befa92ed47ed2af25868412a1275602ca8f4ea Mon Sep 17 00:00:00 2001 From: Arthur Simchaev Date: Mon, 26 Jun 2023 13:33:19 +0300 Subject: scsi: ufs: core: Add support for qTimestamp attribute The new qTimestamp attribute was added to UFS 4.0 spec, in order to synchronize timestamp between device logs and the host. The spec recommends to send this attribute upon device power-on Reset/HW reset or when switching to Active state (using SSU command). Due to this attribute, the attribute's max value was extended to 8 bytes. As a result, the new definition of struct utp_upiu_query_v4_0 was added.
