The probe function is only supposed to initialize the controller
hardware but not the ECC engine. Indeed, we don't know anything about
the NAND chip(s) at this stage. Let's move the logic initializing the
ECC engine, even pretty simple, to the ->attach_chip() hook which gets
called during nand_scan() routine, after the NAND chip discovery. As
the previously mentioned logic is supposed to parse the DT for us, it
is likely that the chip->ecc.* entries be overwritten. So let's avoid
this by moving these lines to ->attach_chip().

Update the USB serial option driver support for the Fibocom NL668 Cat.4
LTE modules as there are actually several different variants.
Got clarifications from Fibocom, there are distinct products:
- VID:PID 1508:1001, NL668 for IOT (no MBIM interface)
- VID:PID 2cb7:01a0, NL668-AM and NL652-EU are laptop M.2 cards (with
MBIM interfaces for Windows/Linux/Chrome OS), respectively for Americas
and Europe.

If UFS host device is in runtime-suspended state while UFS shutdown
callback is invoked, UFS device shall be resumed for register
accesses. Currently only UFS local runtime resume function will be invoked
to wake up the host. This is not enough because if someone triggers
runtime resume from block layer, then race may happen between shutdown and
runtime resume flow, and finally lead to unlocked register access.
To fix this, in ufshcd_shutdown(), use pm_runtime_get_sync() instead of
resuming UFS device by ufshcd_runtime_resume() "internally" to let runtime
PM framework manage the whole resume flow.

Commit 7053e0eab473 ("drm/vram-helper: stop using TTM placement flags")
cleared the BO placement flags if top-down placement had been selected.
Hence, BOs that were supposed to go into VRAM are now placed in a default
location in system memory.
Trying to scanout the incorrectly pinned BO results in displayed garbage
and an error message.

Pull spi fixes from Mark Brown:
"This is a relatively large set of fixes, the bulk of it being a series
from Lukas Wunner which fixes confusion with the lifetime of driver
data allocated along with the SPI controller structure that's been
created as part of the conversion to devm APIs.
The simplest fix, explained in detail in Lukas' commit message, is to
move to a devm_ function for allocation of the controller and hence
driver data in order to push the free of that after anything tries to
reference the driver data in the remove path. This results in a
relatively large diff due to the addition of a new function but isn't
particularly complex.
There's also a fix from Sven van Asbroeck which fixes yet more fallout
from the conflicts between the various different places one can
configure the polarity of GPIOs in modern systems.
Otherwise everything is fairly small and driver specific"

Some users are pairing the Dinovo keyboards with the MX5000 or MX5500
receivers, instead of with the Dinovo receivers. The receivers are
mostly the same (and the air protocol obviously is compatible) but
currently the Dinovo receivers are handled by hid-lg.c while the
MX5x00 receivers are handled by logitech-dj.c.
When using a Dinovo keyboard, with its builtin touchpad, through
logitech-dj.c then the touchpad stops working because when asking the
receiver for paired devices, we get only 1 paired device with
a device_type of REPORT_TYPE_KEYBOARD. And since we don't see a paired
mouse, we have nowhere to send mouse-events to, so we drop them.
Extend the existing fix for the Dinovo Edge for this to also cover the
Dinovo Mini keyboard and also add a mapping to logitech-hidpp for the
Media key on the Dinovo Mini, so that that keeps working too.

Fix an error in the mouse / INPUT(2) descriptor used for quad/bt2.0 combo
receivers. Replace INPUT with INPUT (Data,Var,Abs) for the field for the
4 extra buttons which share their report-byte with the low-res hwheel.
This is likely a copy and paste error. I've verified that the new
0x81, 0x02 value matches both the mouse descriptor for the currently
supported MX5000 / MX5500 receivers, as well as the INPUT(2) mouse
descriptors for the Dinovo receivers for which support is being
worked on.

There's cross-talk on the RPi4 between the 2.4GHz channels used by the WiFi
chip and some resolutions, most notably 1440p at 60Hz.
In such a case, we can either reject entirely the mode, or lower slightly
the pixel frequency to remove the overlap. Let's go for the latter.

This happens because remove_unplugged_switch() calls tb_switch_remove()
that releases the memory pointed by sw so the following lines reference
to a memory that might be released already.
Fix this by saving pointer to the parent device before calling
tb_switch_remove().

The HDMI controller cannot go above a certain pixel rate limit depending on
the generations, but that limit is only enforced in mode_valid at the
moment, which means that we won't advertise modes that exceed that limit,
but the userspace is still free to try to setup a mode that would.
Implement atomic_check to make sure we check it in that scenario too.
