+commit 5949e7c4890c3cf65e783c83c355b95e21f10dba upstream.
+
+[WHAT]
+Since dcn35, DTBCLK can be disabled when no DP2 sink connected for
+power saving purpose.

+
+commit e4bea919584ff292c9156cf7d641a2ab3cbe27b0 upstream.
+
+In `nouveau_bo_move_prep`, if `nouveau_mem_map` fails, an error code
+should be returned. Currently, it returns zero even if vmm addr is not
+correctly mapped.

+
+From: Jann Horn <jannh@google.com>
+
+commit ca2a6abdaee43808034cdb218428d2ed85fd3db8 upstream.
+
+When bailing out due to group_priority_permit() failure, the queue_args
+need to be freed. Fix it by rearranging the function to use the
+goto-on-error pattern, such that the success case flows straight without
+indentation while error cases jump forward to cleanup.

+Subject: drm/rcar-du: dsi: Fix 1/2/3 lane support
+
+From: Marek Vasut <marek.vasut+renesas@mailbox.org>
+
+commit d83f1d19c898ac1b54ae64d1c950f5beff801982 upstream.
+
+Remove fixed PPI lane count setup. The R-Car DSI host is capable
+of operating in 1..4 DSI lane mode. Remove the hard-coded 4-lane
+configuration from PPI register settings and instead configure
+the PPI lane count according to lane count information already
+obtained by this driver instance.
+
+Configure TXSETR register to match PPI lane count. The R-Car V4H
+Reference Manual R19UH0186EJ0121 Rev.1.21 section 67.2.2.3 Tx Set
+Register (TXSETR), field LANECNT description indicates that the
+TXSETR register LANECNT bitfield lane count must be configured
+such, that it matches lane count configuration in PPISETR register
+DLEN bitfield. Make sure the LANECNT and DLEN bitfields are
+configured to match.

+Subject: drm/xe/uapi: loosen used tracking restriction
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Matthew Auld <matthew.auld@intel.com>
+
+commit 2d1684a077d62fddfac074052c162ec6573a34e1 upstream.
+
+Currently this is hidden behind perfmon_capable() since this is
+technically an info leak, given that this is a system wide metric.
+However the granularity reported here is always PAGE_SIZE aligned, which
+matches what the core kernel is already willing to expose to userspace
+if querying how many free RAM pages there are on the system, and that
+doesn't need any special privileges. In addition other drm drivers seem
+happy to expose this.
+
+The motivation here if with oneAPI where they want to use the system
+wide 'used' reporting here, so not the per-client fdinfo stats. This has
+also come up with some perf overlay applications wanting this
+information.
