The 'gpu' and 'firmware' nodes are not MMIO devices, so they should not be
under a 'simple-bus'. Additionally, the "raspberrypi,bcm2835-power" node
is part of the firmware, so move it under the 'rpi-firmware' node.

The BCM63148 has a brcmper I2C block.
The peripheral range needs to be extended to accommodate
it. The Boot LUT is at offset + 0x10000 so extend it to
cover at least that too, 128 KB.
INTERRUPT_ID_I2C is at (ISR_TABLE3_OFFSET + 19) = 96+19 = 115,

The valid range for the pulses-per-revolution devicetree property is
1..4. The current code checks for a range of 1..5. Fix it.
Declare the variable used to retrieve pulses per revolution from
devicetree as u32 (unsigned) to match the of_property_read_u32() API.
The current code uses a postfix decrement when writing the pulses per
resolution into the chip. This has no effect since the value is evaluated
before it is decremented. Fix it by decrementing before evaluating the
value.

While testing ABI changes across all architectures, I found that abidiff
sometimes produces nonsensical output. Further debugging identified
missing or broken libelf support for architecture specific relocations
in ET_REL binaries as the source of the problem[1].
Change the script to no longer produce a relocatable object file but
instead create a shared library for each header. This makes abidiff
work for all of the architectures in upstream linux kernels.

Currently, the VFIO DSA driver test only supports the SPR DSA device ID.
Attempting to run the test on newer platforms like DMR or GNR-D results
in a "No driver found" error, causing the test to be skipped.
Refactor dsa_probe() to use a switch statement for checking device IDs.
This improves maintainability and makes it easier to add new device IDs
in the future.
Add the following DSA device IDs to the supported list:
PCI_DEVICE_ID_INTEL_DSA_DMR (0x1212)

Commit 150a04d817 ("compiler_types.h: Attributes: Add __counted_by_ptr

__counted_by_ptr, which made sense while 22.0.0 was the version of
LLVM's main branch to allow developers to easily test and develop uses
of __counted_by_ptr in their code. However, __counted_by_ptr requires a
change [1] merged towards the end of the 22 development cycle to avoid
errors when applied to void pointers.

This is disruptive for deployed prerelease clang-22 builds (such as
Android LLVM) or when bisecting between llvmorg-21-init and the fix.

All MIPS ISAs before r6 use the 'lo' and 'hi' special registers.
These are clobbered by system calls and need to be marked as such to
avoid miscompilations. Currently nolibc ties the clobbers to the ABI.
But this is wrong and leads to ISA<->ABI combinations which are not
handled correctly, leading to compiler errors or miscompilations.

Octal output isn't often used, but adding it costs very little.
Supporting "%#o" is mildly annoying, it has to add a leading '0' if
there isn't one present. In simple cases this is the same as adding a sign
of '0' - but that adds an extra '0' in a few places.
So you need 3 tests, %o, # and no leading '0' (which can only be checked
after the zero pad for precision).
If all the test are deferred until after zero padding then too many values
are 'live' across the call to _nolibc_u64toa_base() and get spilled to stack.
Hence the check that ignores the 'sign' if it is the same as the first
character of the output string.
Add tests for octal output.
