Considering the current transition of the GPIO subsystem, remove all
dependencies of the legacy GPIO interface (linux/gpio.h and linux
/of_gpio.h) and replace it with the descriptor-based GPIO approach.

Several DRM/KMS atomic commits can run in parallel if they affect
different CRTC. These commits share the global HVS state, so we have
some code to make sure we run commits in sequence. This synchronization
code is one of the first thing that runs in vc4_atomic_commit_tail().
Another constraints we have is that we need to make sure the HVS clock
gets a boost during the commit. That code relies on clk_set_min_rate and
will remove the old minimum and set a new one. We also need another,
temporary, minimum for the duration of the commit.
The algorithm is thus to set a temporary minimum, drop the previous
one, do the commit, and finally set the minimum for the current mode.
However, the part that sets the temporary minimum and drops the older
one runs before the commit synchronization code.
Thus, under the proper conditions, we can end up mixing up the minimums
and ending up with the wrong one for our current step.
To avoid it, let's move the clock setup in the protected section.

There are a few details specific to the GETFB2 IOCTL.
It's not immediately clear how user-space should check for the
number of planes. Suggest using the handles field or the pitches
field.
The modifier array is filled with zeroes, ie. DRM_FORMAT_MOD_LINEAR.
So explicitly tell user-space to not look at it unless the flag is
set.
Changes in v2 (Daniel):
- Mention that handles should be used to compute the number of planes,
and only refer to pitches as a fallback.
- Reword bit about undefined modifier.

Collect the dipslay related mask under the display sub-structure
in intel_device_info.
Note that there is a slight change in behaviour in that we zero
out .display entirely when !HAS_DISPLAY (aka. pipe_mask==0), so
now we also zero out the other masks (although cpu_transocder_mask
should already be zero of pipe_mask is zero). abox_mask is
only used by the display core init when HAS_DISPLAY is true, so
the actual behaviour of the system shouldn't change despite the
zeroing of these masks.
There is a lot more display stuff directly in device info that
could be moved over. Maybe someone else will be inspired to do it...

Using cluster topology on hybrid CPUs, e.g. Alder Lake, biases the
scheduler towards the ATOM cluster as that has more total capacity.
Use selection based on CPU priority instead.

Using standard USB_EP_MAXP_MULT_MASK instead of individual bits for

The checks performed by commit aed9d65ac327 ("USB: validate
wMaxPacketValue entries in endpoint descriptors") require that initial
value of the maxp variable contains both maximum packet size bits
(10..0) and multiple-transactions bits (12..11). However, the existing
code assings only the maximum packet size bits. This patch assigns all
bits of wMaxPacketSize to the variable.

Under some conditions, USB gadget devices can show allocated buffer
contents to a host. Fix this up by zero-allocating them so that any
extra data will all just be zeros.

Sometimes USB hosts can ask for buffers that are too large from endpoint
0, which should not be allowed. If this happens for OUT requests, stall
the endpoint, but for IN requests, trim the request size to the endpoint
buffer size.

Pull xfs fix from Darrick Wong:
"This fixes a race between a readonly remount process and other
processes that hold a file IOLOCK on files that previously experienced
copy on write, that could result in severe filesystem corruption if
the filesystem is then remounted rw.
I think this is fairly rare (since the only reliable reproducer I have
that fits the second criteria is the experimental xfs_scrub program),
but the race is clear, so we still need to fix this.

process failing to clear all speculative preallocations from files

a few releases ago and was just reported recently.
The other is just a minor dependency clean up.

of what seems to be a bug in hotplug for a special situation with
memoryless nodes. Michal Hocko is digging into it further"
