d0c9a21c8e MTD device changes: Aside from the platform_driver::remove() switch, two
misc issues got fixed.
 
 SPI-NAND changes:
 A load of fixes to Winbond manufacturer driver have been done, plus a
 structure constification.
 
 Raw NAND changes:
 The GPMI driver has been improved on the power management side.
 The Davinci driver has been cleaned up.
 A leak in the Atmel driver plus some typos in the core have been fixed.
 
 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.

f2ef39727a spi: Updates for v6.13
The only real core work we've got this time around is the completion of
 the transition to the new host/target naming for the core APIs, Kconfig
 still needs doing but that's a lot less invasive.  Otherwise the big
 changes are the new drivers that have been added:
 
  - Completion of the conversion to spi_alloc_host()/_target() and
    removal of the old naming.
  - Cleanups for Rockchip drivers, these brought in a new logging helper
    in the driver core for warnings during probe.
  - Support for configuration of the word delay via spidev_test.
  - Support for AMD HID2 controllers, Apple SPI controller and Realtek
    SPI-NAND controllers.

af264e5989 mtd: spinand: Constify struct nand_ecc_engine_ops
'struct nand_ecc_engine_ops' are not modified in these drivers.

Constifying this structure moves some data to a read-only section, so
increases overall security, especially when the structure holds some
function pointers.

Update the prototype of mxic_ecc_get_pipelined_ops() accordingly.

spi: Switch back to struct platform_driver::remove()
After commit 0edb555a65 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/spi to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

The change for the spi-npcm-fiu stands out in the diffstat because the
inconsistent formatting style of the platform_driver initializer is
fixed to match the other struct initializer in the file.

spi: Use devm_clk_get_*() helper function to
Merge series from Li Zetao <lizetao1@huawei.com>:

Commit 7ef9651e97 ("clk: Provide new devm_clk helpers for prepared
and enabled clocks") provides a new helper function for prepared and
enabled clocks when a driver keeps a clock prepared (or enabled) during
the whole lifetime of the driver. So where drivers get clocks and enable
them immediately, it can be combined into a single function
devm_clk_get_*(). Moreover, the unprepare and disable function
has been registered to devm_clk_state, and before devm_clk_state is
released, the clocks will be unprepareed and disable, so it is unnecessary
to unprepare and disable clocks explicitly when remove drivers or in the
error handling path.

spi: mtk-snfi: Use helper function devm_clk_get_enabled()
Since commit 7ef9651e97 ("clk: Provide new devm_clk helpers for prepared
and enabled clocks"), devm_clk_get() and clk_prepare_enable() can now be
replaced by devm_clk_get_enabled() when driver enables (and possibly
prepares) the clocks for the whole lifetime of the device. Moreover, it is
no longer necessary to unprepare and disable the clocks explicitly.
Also, devm_clk_get_optional() and clk_prepare_enable() can now be
replaced by devm_clk_get_optional_enabled().Moreover, the two functions
mtk_snand_enable_clk() and mtk_snand_disable_clk() no longer are used,
drop them for clean code.

spi: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

spi: mtk-snfi: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.
