The Aspeed pinctl schema have errors in the 'compatible' schema:

properties:compatible:enum: ['aspeed', 'ast2500-pinctrl', 'aspeed', 'g5-pinctrl'] has non-unique elements

Flow style sequences have to be quoted if the vales contain ','. Fix
this by using the more common one line per entry formatting.

Matching on the 'cpus' node was a bad choice because the schema is
incorrectly applied to non-RiscV cpus nodes. As we now have a common cpus
schema which checks the general structure, it is also redundant to do so
in the Risc-V CPU schema.

The downside is one could conceivably mix different architecture's cpu
nodes or have typos in the compatible string. The latter problem pretty
much exists for every schema.

Properties which are child node definitions need to have an explict
type. Otherwise, a matching (DT) property can silently match when an
error is desired. Fix this up tree-wide. Once this is fixed, the
meta-schema will enforce this on any child node definitions.

Pull ARM Devicetree updates from Olof Johansson:
 "We continue to see a lot of new material. I've highlighted some of it
  below, but there's been more beyond that as well.

  One of the sweeping changes is that many boards have seen their ARM
  Mali GPU devices added to device trees, since the DRM drivers have now
  been merged.

  So, with the caveat that I have surely missed several great
  contributions, here's a collection of the material this time around:

  New SoCs:

   - Mediatek mt8183 (4x Cortex-A73 + 4x Cortex-A53)

   - TI J721E (2x Cortex-A72 + 3x Cortex-R5F + 3 DSPs + MMA)

   - Amlogic G12B (4x Cortex-A73 + 2x Cortex-A53)

  New Boards / platforms:

   - Aspeed BMC support for a number of new server platforms

   - Kontron SMARC SoM (several i.MX6 versions)

   - Novtech's Meerkat96 (i.MX7)

   - ST Micro Avenger96 board

   - Hardkernel ODROID-N2 (Amlogic G12B)

   - Purism Librem5 devkit (i.MX8MQ)

   - Google Cheza (Qualcomm SDM845)

   - Qualcomm Dragonboard 845c (Qualcomm SDM845)

   - Hugsun X99 TV Box (Rockchip RK3399)

   - Khadas Edge/Edge-V/Captain (Rockchip RK3399)

  Updated / expanded boards and platforms:

   - Renesas r7s9210 has a lot of new peripherals added

   - Fixes and polish for Rockchip-based Chromebooks

   - Amlogic G12A has a lot of peripherals added

   - Nvidia Jetson Nano sees various fixes and improvements, and is now
     at feature parity with TX1"

  mm: make register_mem_sect_under_node() static
  ...

Commit c5c27a0a ("x86/stacktrace: Remove the pointless ULONG_MAX
marker") removes ULONG_MAX marker from user stack trace entries but
trace_user_stack_print() still uses the marker and it outputs unnecessary
"??".

For example:

            less-1911  [001] d..2    34.758944: <user stack trace>
   =>  <00007f16f2295910>
   => ??
   => ??
   => ??
   => ??
   => ??
   => ??
   => ??

The user stack trace code zeroes the storage before saving the stack, so if
the trace is shorter than the maximum number of entries it can terminate
the print loop if a zero entry is detected.

In nouveau_conn_reset(), if connector->state is true,
__drm_atomic_helper_connector_destroy_state() will be called,
but the memory pointed by asyc isn't freed. Memory leak happens
in the following function __drm_atomic_helper_connector_reset(),
where newly allocated asyc->state will be assigned to connector->state.

So using nouveau_conn_atomic_destroy_state() instead of
__drm_atomic_helper_connector_destroy_state to free the "old" asyc.

Here the is the log showing memory leak.

It turns out that while disabling i2c bus access from software when the
GPU is suspended was a step in the right direction with:

commit 342406e4 ("drm/nouveau/i2c: Disable i2c bus access after
->fini()")

We also ended up accidentally breaking the vbios init scripts on some
older Tesla GPUs, as apparently said scripts can actually use the i2c
bus. Since these scripts are executed before initializing any
subdevices, we end up failing to acquire access to the i2c bus which has
left a number of cards with their fan controllers uninitialized. Luckily
this doesn't break hardware - it just means the fan gets stuck at 100%.

This also means that we've always been using our i2c busses before
initializing them during the init scripts for older GPUs, we just didn't
notice it until we started preventing them from being used until init.
It's pretty impressive this never caused us any issues before!

So, fix this by initializing our i2c pad and busses during subdev
pre-init. We skip initializing aux busses during pre-init, as those are
guaranteed to only ever be used by nouveau for DP aux transactions.

Previously center scaling would get scaling applied to it (when it was
only supposed to center the image), and aspect-corrected scaling did not
always correctly pick whether to reduce width or height for a particular
combination of inputs/outputs.

Higher layers tend to add a lot of modes not actually in the EDID, such
as the standard DMT modes. Changing this would be extremely intrusive to
everyone, so just force the scaler more often. There are no practical
cases we're aware of where a LVDS/eDP panel has multiple resolutions
exposed, and i915 already does it this way.

There are two generations of tlb operation instruction for C-SKY.
First generation is use mcr register and it need software do more
things, second generation is use specific instructions, eg:
 tlbi.va, tlbi.vas, tlbi.alls

We implemented the following functions:

 - flush_tlb_range (a range of entries)
 - flush_tlb_page (one entry)

 Above functions use asid from vma->mm to invalid tlb entries and
 we could use tlbi.vas instruction for newest generation csky cpu.

 - flush_tlb_kernel_range
 - flush_tlb_one

 Above functions don't care asid and it invalid the tlb entries only
 with vpn and we could use tlbi.vaas instruction for newest generat-
 ion csky cpu.

This patch only contains asid help code from arm for next patch to
use.

The asid allocator use five level check to reduce the cost of
switch_mm.

 1. Check if the asid version is the same (it's general)
 2. Check reserved_asid which is set in rollover flush_context()
    and key point is to keep the same bit position with the current
    asid version instead of input version.
 3. Check if the position of bitmap is free then it could be set &
    used directly.
 4. find_next_zero_bit() (a little performance cost)
 5. flush_context  (this is the worst cost with increase current asid
    version)

Check is level by level and cost is also higher with the next level.
The reserved_asid and bitmap mechanism prevent unnecessary
find_next_zero_bit().

The atomic 64 bit asid is also suitable for 32-bit system and it
won't cost a lot in 1th 2th 3th level check.

The operation of set/clear mm_cpumask was removed in arm64 compared to
arm32. It seems no side effect on current arm64 system, but from
software meaning it's wrong. Although csky also needn't it, we add it
back for csky.

The asid_per_ctxt is no use for csky and it reserves the lowest bits for
other use, maybe: trust zone ? Ok, just keep it in csky copy.

Seems it also could be used by other archs and it's worth to move asid
code to generic in future.
