When a USB device gets plugged on ASUS PRIME B350M-A's front ports, the
xHC stops working:
[ 549.114587] xhci_hcd 0000:02:00.0: WARN: xHC CMD_RUN timeout
[ 549.114608] suspend_common(): xhci_pci_suspend+0x0/0xc0 returns -110
[ 549.114638] xhci_hcd 0000:02:00.0: can't suspend (hcd_pci_runtime_suspend returned -110)
Delay before running xHC command CMD_RUN can workaround the issue.
Use a new quirk to make the delay only targets to the affected xHC.

This patch reverts the commit 835e4241e714 ("usb: host: xhci-plat:
enable clk in resume timing") because this driver also has runtime PM
and the commit 560869100b99 ("clk: renesas: cpg-mssr: Restore module
clocks during resume") will restore the clock on R-Car H3 environment.
If the xhci_plat_suspend() disables the clk, the system cannot enable
the clk in resume like the following behavior:
< In resume >
- genpd_resume_noirq() runs and enable the clk (enable_count = 1)
- cpg_mssr_resume_noirq() restores the clk register.
-- Since the clk was disabled in suspend, cpg_mssr_resume_noirq()
will disable the clk and keep the enable_count.
- Even if xhci_plat_resume() calls clk_prepare_enable(), since
the enable_count is 1, the clk will be not enabled.
After this patch is applied, the cpg-mssr driver will save the clk
as enable, so the clk will be enabled in resume.

The following commit:
commit aa4d86163e4e ("block: loop: switch to VFS ITER_BVEC")
replaced __do_lo_send_write(), which used ITER_KVEC iterators, with
lo_write_bvec() which uses ITER_BVEC iterators. In this change, though,
the WRITE flag was lost:
- iov_iter_kvec(&from, ITER_KVEC | WRITE, &kvec, 1, len);
+ iov_iter_bvec(&i, ITER_BVEC, bvec, 1, bvec->bv_len);
This flag is necessary for the DAX case because we make decisions based on
whether or not the iterator is a READ or a WRITE in dax_iomap_actor() and
in dax_iomap_rw().
We end up going through this path in configurations where we combine a PMEM
device with 4k sectors, a loopback device and DAX. The consequence of this
missed flag is that what we intend as a write actually turns into a read in
the DAX code, so no data is ever written.
The very simplest test case is to create a loopback device and try and
write a small string to it, then hexdump a few bytes of the device to see
if the write took. Without this patch you read back all zeros, with this
you read back the string you wrote.
For XFS this causes us to fail or panic during the following xfstests:
xfs/074 xfs/078 xfs/216 xfs/217 xfs/250
For ext4 we have a similar issue where writes never happen, but we don't
currently have any xfstests that use loopback and show this issue.
Fix this by restoring the WRITE flag argument to iov_iter_bvec(). This
causes the xfstests to all pass.

Corrected four outstanding issues in the transport around sqsize.
1: Create Connection LS is sending the 1's-based sqsize, should be
sending the 0's-based value.
2: allocation of hw queue is using the 0's-base size. It should be
using the 1's-based value.
3: normalization of ctrl.sqsize by MQES is using MQES+1 (1's-based
value). It should be MQES (0's-based value).
4: Missing clause to ensure queue_count not larger than ctrl->sqsize.
Corrected by:
Clean up routines that pass queue size around. The queue size value is
the actual count (1's-based) value and determined from ctrl->sqsize + 1.
Routines that send 0's-based value adapt from queue size.
Sset ctrl->sqsize properly for MQES.
Added clause to nsure queue_count not larger than ctrl->sqsize + 1.

This removes a dependency on the order options are passed when creating
a fabrics controller. With the old code, if "nr_io_queues" appears before
an "nqn" option specifying the discovery controller, then nr_io_queues
is overridden with zero. If "nr_io_queues" appears after specifying the
discovery controller, then the nr_io_queues option is used to set the
number of queues, and the driver attempts to establish IO connections
to the discovery controller (which doesn't work).
It seems better to ignore (and warn about) the "nr_io_queues" option
if userspace has already asked to connect to the discovery controller.

This reverts commit 48282969826b3d3c76e908182f69724d86d995fe which
caused the following issues:
1. On T460p with BIOS version 2.22 touchpad and trackpoint stop working
after suspend-resume cycle. Due to strange state of the device another
suspend is impossible.
The following dmesg errors can be observed:
thinkpad_acpi: EC reports that Thermal Table has changed

rmi4_physical rmi4-00: rmi_driver_set_irq_bits: Failed to change enabled interrupts!
psmouse: probe of serio3 failed with error -1
2. On another T460p with BIOS version 2.15 two finger scrolling gesture
on the touchpad stops working after suspend-resume cycle (about 75%
reproducibility, when it still works, the scrolling gesture becomes
laggy). Nothing suspicious appears in the dmesg.
Analysis form Richard Schütz:
"RMI is unreliable on the ThinkPad T460p because the device is affected
by the firmware behavior addressed in a7ae81952cda ("i2c: i801: Allow
ACPI SystemIO OpRegion to conflict with PCI BAR")."
The affected devices often show:
i801_smbus 0000:00:1f.4: BIOS is accessing SMBus registers

HW Engineer's Notes:
During switch from vga->extended, if we set the VGA_TEST_ENABLE and then
hit the VGA_TEST_RENDER_START, then the DCHUBP timing gets updated correctly.
Then vBIOS will have it poll for the VGA_TEST_RENDER_DONE and unset
VGA_TEST_ENABLE, to leave it in the same state as before.

While checking plane states for updates during atomic check, we create
dc_plane_states in preparation. These dc states should be freed if
something errors.
Although the input transfer function is also freed by
dc_plane_state_release(), we should free it (on error) under the same
scope as where it is created.

Move cursor programming to inside the OTG_MASTER_UPDATE_LOCK
If graphics plane go from 1 pipe to hsplit, the cursor updates
after mpc programming and unlock. Which means there is a window
of time where cursor is enabled on the wrong pipe if it's on
the right side of the screen (i.e. case where cursor need to
move from pipe 0 to pipe 3 post split). This will cause pstate hang.
Solution is to program the cursor while still locked.

other place that calls it directly. Make sure we call the helper
functions always since we need to update a bunch of things in stream and

The below commit
"drm/atomic: Try to preserve the crtc enabled state in drm_atomic_remove_fb, v2"
introduces a slight behavioral change to rmfb. Instead of disabling a crtc
when the primary plane is disabled, it now preserves it.
This change leads to BUG hit while performing atomic commit on amd driver.
As a fix this patch ensures that we disable the CRTC's with NULL FB by returning
-EINVAL and hence triggering fall back to the old behavior and turning off the
crtc in atomic_remove_fb().
V2: Added error check for plane_state and removed sanity check for crtc.

There have been many reports of Ellesmere and Baffin systems not being
able to drive HDMI 4k60 due to the fact that we check the HDMI_6GB_EN
bit from VBIOS table. Windows seems to not have this issue.
On some systems we fail to the encoder cap info from VBIOS. In that case
we should default to enabling HDMI6G support.
