Negative temperatures are reported as large positive temperatures
due to missing sign extension from unsigned int to long. Cast unsigned
raw register values to signed before performing the calculations
to fix the problem.

"MTD device changes:
- switch platform_driver back to remove()
- misc fixes
SPI-NAND changes:
- a load of fixes to Winbond manufacturer driver
- structure constification
Raw NAND changes:
- improve the power management of the GPMI driver
- Davinci driver clean-ups
- fix leak in the Atmel driver
- fix some typos in the core
SPI NOR changes:
- Introduce byte swap support for 8D-8D-8D mode and a user for it:
macronix.
SPI NOR flashes may swap the bytes on a 16-bit boundary when
configured in Octal DTR mode. For such cases the byte order is
propagated through SPI MEM to the SPI controllers so that the
controllers swap the bytes back at runtime. This avoids breaking
the boot sequence because of the endianness problems that appear
when the bootloaders use 1-1-1 and the kernel uses 8D-8D-8D with
byte swap support. Along with the SPI MEM byte swap support we
queue a patch for the SPI MXIC controller that swaps the bytes back
at runtime"

sheer amount of new drivers is uncommon, so I'm anticipating a larger
number of fixes for clk drivers this cycle.

To avoid arch-specific code in general ACPI initialization flow,
introduce a weak symbol acpi_arch_init().
Currently, arm64 and riscv can utillize this to insert their
arch-specific flow.
In the future, other architectures can also have a chance to define
their own arch-specific ACPI initialization process if necessary.

The Acer Iconia One 8 A1-840 (not to be confused with the A1-840FHD which

Also add the "INT33F5" HID for the TI PMIC used on this tablet to the list

When there is a hardware error, the NPU firmware notifies the host through
a mailbox message. The message includes details of the error, such as the
tile and column indexes where the error occurred.
The driver starts a thread to handle the NPU error message. The thread
stops the clients which are using the column where error occurred. Then
the driver resets that column.

Now that the main domain allocating path is calling this function it
doesn't make sense to leave it named _user. Change the name to
alloc_paging_flags() to mirror the new iommu_paging_domain_alloc_flags()
function.
A driver should implement only one of ops->domain_alloc_paging() or
ops->domain_alloc_paging_flags(). The former is a simpler interface with
less boiler plate that the majority of drivers use. The latter is for
drivers with a greater feature set (PASID, multiple page table support,
advanced iommufd support, nesting, etc). Additional patches will be needed
to achieve this.

It turns out all the drivers that are using this immediately call into
another function, so just make that function directly into the op. This
makes paging=NULL for domain_alloc_user and we can remove the argument in
the next patch.
The function mirrors the similar op in the viommu that allocates a nested
domain on top of the viommu's nesting parent. This version supports cases
where a viommu is not being used.

Re-introduce a line-by-line composition algorithm for each pixel format.
This allows more performance by not requiring an indirection per pixel
read. This patch is focused on readability of the code.
Line-by-line composition was introduced by [1] but rewritten back to
pixel-by-pixel algorithm in [2]. At this time, nobody noticed the impact
on performance, and it was merged.
This patch is almost a revert of [2], but in addition efforts have been
made to increase readability and maintainability of the rotation handling.
The blend function is now divided in two parts:
- Transformation of coordinates from the output referential to the source
referential
- Line conversion and blending
Most of the complexity of the rotation management is avoided by using
drm_rect_* helpers. The remaining complexity is around the clipping, to
avoid reading/writing outside source/destination buffers.
The pixel conversion is now done line-by-line, so the read_pixel_t was
replaced with read_pixel_line_t callback. This way the indirection is only
required once per line and per plane, instead of once per pixel and per
plane.
The read_line_t callbacks are very similar for most pixel format, but it
is required to avoid performance impact. Some helpers for color
conversion were introduced to avoid code repetition:
- *_to_argb_u16: perform colors conversion. They should be inlined by the
compiler, and they are used to avoid repetition between multiple variants
of the same format (argb/xrgb and maybe in the future for formats like
bgr formats).
This new algorithm was tested with:
- kms_plane (for color conversions)
- kms_rotation_crc (for rotations of planes)
- kms_cursor_crc (for translations of planes)
- kms_rotation (for all rotations and formats combinations) [3]
The performance gain was mesured with kms_fb_stress [4] with some
modification to fix the writeback format.
The performance improvement is around 5 to 10%.
