The generic FourCC format always prints the data using the big endian
order. It is generic because it allows to read the data using a custom
ordering.
The current code uses "n" for reading data in the reverse host ordering.
It makes the 4 variants [hnbl] consistent with the generic printing
of IPv4 addresses.
Unfortunately, it creates confusion on big endian systems. For example,
it shows the data &(u32)0x67503030 as
%p4cn 00Pg (0x30305067)
But people expect that the ordering stays the same. The network ordering
is a big-endian ordering.
The problem is that the semantic is not the same. The modifiers affect
the output ordering of IPv4 addresses while they affect the reading order
in case of FourCC code.
Avoid the confusion by replacing the "n" modifier with "hR", aka
reverse host ordering. It is inspired by the existing %p[mM]R printf
format.

%p4cc is designed for DRM/V4L2 FourCCs with their specific quirks, but
it's useful to be able to print generic 4-character codes formatted as
an integer. Extend it to add format specifiers for printing generic
32-bit FourCCs with various endian semantics:
%p4ch Host byte order
%p4cn Network byte order
%p4cl Little-endian
%p4cb Big-endian
The endianness determines how bytes are interpreted as a u32, and the
FourCC is then always printed MSByte-first (this is the opposite of
V4L/DRM FourCCs). This covers most practical cases, e.g. %p4cn would
allow printing LSByte-first FourCCs stored in host endian order
(other than the hex form being in character order, not the integer
value).

Add a DT binding for the Visionox G2647FB105, a 6.47 inch 1080x2340
MIPI-DSI CMD mode AMOLED panel used in:
- Xiaomi Mi Note 10 / CC9 Pro (sm7150-xiaomi-tucana)
- Xiaomi Mi Note 10 Lite (sm7150-xiaomi-toco)
Xiaomi likes to use different panels in various revisions of the same
device. A factory panel even can be replaced with another model in a
service center.
So, the power configuration of this panel is similar to
some Samsung AMOLED panels, e.g. samsung,ams639rq08, which can be found on
other sm7150 Xiaomi devices. Even though Samsung panels weren't used
in sm7150-xiaomi-tucana and toco, the described voltage rails exist
(confirmed by schematics of the device).

The first compatible strings added for the AXE-1-16M are not sufficient to
accurately describe all the IMG Rogue GPUs. The current "img,img-axe"
string refers to the entire family of Series AXE GPUs, but this is
primarily a marketing term and does not denote a level of hardware
similarity any greater than just "Rogue".
The more specific "img,img-axe-1-16m" string refers to individual AXE-1-16M
GPU. For example, unlike the rest of the Series AXE GPUs, the AXE-1-16M
only uses a single power domain.
The situation is actually slightly worse than described in the first
paragraph, since many "series" (such as Series BXS found in the TI AM68
among others and added later in this series) contain cores with both Rogue
and Volcanic architectures.
Besides attempting to move away from vague groupings defined only
by marketing terms, we want to draw a line between properties inherent to
the IP core and choices made by the silicon vendor at integration time.
For instance, the number of power domains is a property of the IP core,
whereas the decision to use one or multiple clocks is a vendor one.
In the original compatible strings, we must use "ti,am62-gpu" to constrain
both of these properties since the number of power domains cannot be fixed
for "img,img-axe".
Work is currently underway to add support for volcanic-based Imagination
GPUs, for which bindings will be added in "img,powervr-volcanic.yaml".
As alluded to previously, the split between rogue and volcanic cores is
non-obvious at times, so add a generic top-level "img,img-rogue" compatible
string here to allow for simpler differentiation in devicetrees without
referring back to the bindings.
The currently supported GPU (AXE-1-16M) only requires a single power
domain. Subsequent patches will add support for BXS-4-64 MC1, which has
two power domains. Add infrastructure now to allow for this.
Also allow the dma-coherent property to be added to IMG Rogue GPUs, which
are DMA devices. The decision for coherency is made at integration time and
this property should be applied wherever it accurately describes the
vendor integration.
Note that the new required properties for power domains are conditional on
the new base compatible string to avoid an ABI break.

First of all, using 'mmio' prevents proper implementation of 8-bit accessors.
Second, it's simply inconsistent with uart8250 set of options. Rename it to
'mmio32'. While at it, remove rather misleading comment in the documentation.
From now on mmio32 is self-explanatory and pciserial supports not only 32-bit
MMIO accessors.
Also, while at it, fix the comment for the "pciserial" case. The comment
seems to be a copy'n'paste error when mentioning "serial" instead of
"pciserial" (with double quotes). Fix this.
With that, move it upper, so we don't calculate 'buf' twice.

This adds the UAPI for the Asahi driver targeting the GPU in the Apple
M1 and M2 series systems on chip. The UAPI design is based on other
modern Vulkan-capable drivers, including Xe and Panthor. Memory
management is based on explicit VM management. Synchronization is
exclusively explicit sync.
This UAPI is validated against our open source Mesa stack, which is
fully conformant to the OpenGL 4.6, OpenGL ES 3.2, OpenCL 3.0, and
Vulkan 1.4 standards. The Vulkan driver supports sparse, exercising the
VM_BIND mechanism.
This patch adds the standalone UAPI header. It is implemented by an open
source DRM driver written in Rust. We fully intend to upstream this
driver when possible. However, as a production graphics driver, it
depends on a significant number of Rust abstractions that will take a
long time to upstream. In the mean time, our userspace is upstream in
Mesa but is not allowed to probe with upstream Mesa as the UAPI is not
yet reviewed and merged in the upstream kernel. Although we ship a
patched Mesa in Fedora Asahi Remix, any containers shipping upstream
Mesa builds are broken for our users, including upstream Flatpak and
Waydroid runtimes. Additionally, it forces us to maintain forks of Mesa
and virglrenderer, which complicates bisects.
The intention in sending out this patch is for this UAPI to be
thoroughly reviewed. Once we as the DRM community are satisfied with the
UAPI, this header lands signifying that the UAPI is stable and must only
be evolved in backwards-compatible ways; it will be the UAPI implemented
in the DRM driver that eventually lands upstream. That promise lets us
enable upstream Mesa, solving all these issues while the upstream Rust
abstractions are developed.
https://github.com/alyssarosenzweig/linux/commits/agx-uapi-v7 contains
the DRM driver implementing this proposed UAPI.
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/33984 contains
the Mesa patches to implement this proposed UAPI.
That Linux and Mesa branch together give a complete graphics/compute
stack on top of this UAPI.

Pull RISC-V updates from Palmer Dabbelt:
- The sub-architecture selection Kconfig system has been cleaned up,
the documentation has been improved, and various detections have been
fixed
- The vector-related extensions dependencies are now validated when
parsing from device tree and in the DT bindings
- Misaligned access probing can be overridden via a kernel command-line
parameter, along with various fixes to misalign access handling
- Support for relocatable !MMU kernels builds
- Support for hpge pfnmaps, which should improve TLB utilization
- Support for runtime constants, which improves the d_hash()
performance
- Support for bfloat16, Zicbom, Zaamo, Zalrsc, Zicntr, Zihpm
- Various fixes, including:
- We were missing a secondary mmu notifier call when flushing the
tlb which is required for IOMMU
- Fix ftrace panics by saving the registers as expected by ftrace
- Fix a couple of stimecmp usage related to cpu hotplug
- purgatory_start is now aligned as per the STVEC requirements
- A fix for hugetlb when calculating the size of non-present PTEs

Pull networking fixes from Jakub Kicinski:
"Including fixes from netfilter.
Current release - regressions:
- four fixes for the netdev per-instance locking
Current release - new code bugs:
- consolidate more code between existing Rx zero-copy and uring so
that the latter doesn't miss / have to duplicate the safety checks
Previous releases - regressions:
- ipv6: fix omitted Netlink attributes when using SKIP_STATS
Previous releases - always broken:
- net: fix geneve_opt length integer overflow
- udp: fix multiple wrap arounds of sk->sk_rmem_alloc when it
approaches INT_MAX
- dsa: mvpp2: add a lock to avoid corruption of the shared TCAM
- dsa: airoha: fix issues with traffic QoS configuration / offload,
and flow table offload
Misc:
- touch up the Netlink YAML specs of old families to make them usable
for user space C codegen"

YAML specs don't normally include the C prefix name in the name
of the YAML attr. Remove the ifa- prefix from all attributes
in route-attrs and metrics and specify name-prefix instead.
This is a bit risky, hopefully there aren't many users out there.
