02e2af20f4 Char/Misc and other driver updates for 5.18-rc1
Here is the big set of char/misc and other small driver subsystem
 updates for 5.18-rc1.
 
 Included in here are merges from driver subsystems which contain:
 	- iio driver updates and new drivers
 	- fsi driver updates
 	- fpga driver updates
 	- habanalabs driver updates and support for new hardware
 	- soundwire driver updates and new drivers
 	- phy driver updates and new drivers
 	- coresight driver updates
 	- icc driver updates
 
 Individual changes include:
 	- mei driver updates
 	- interconnect driver updates
 	- new PECI driver subsystem added
 	- vmci driver updates
 	- lots of tiny misc/char driver updates
 
 There will be two merge conflicts with your tree, one in MAINTAINERS
 which is obvious to fix up, and one in drivers/phy/freescale/Kconfig
 which also should be easy to resolve.
 
 All of these have been in linux-next for a while with no reported
 problems.

ad9c6ee642 spi: Updates for v5.18
The overwhelming bulk of this pull request is a change from Uwe
 Kleine-König which changes the return type of the remove() function to
 void as part of some wider work he's doing to do this for all bus types,
 causing updates to most SPI device drivers.  The branch with that on has
 been cross merged with a couple of other trees which added new SPI
 drivers this cycle, I'm not expecting any build issues resulting from
 the change.
 
 Otherwise it's been a relatively quiet release with some new device
 support, a few minor features and the welcome completion of the
 conversion of the subsystem to use GPIO descriptors rather than numbers:
 
  - Change return type of remove() to void.
  - Completion of the conversion of SPI controller drivers to use GPIO
    descriptors rather than numbers.
  - Quite a few DT schema conversions.
  - Support for multiple SPI devices on a bus in ACPI systems.
  - Big overhaul of the PXA2xx SPI driver.
  - Support for AMD AMDI0062, Intel Raptor Lake, Mediatek MT7986 and
    MT8186, nVidia Tegra210 and Tegra234, Renesas RZ/V2L, Tesla FSD and
    Sunplus SP7021.

ceef4cf97b mtd: tests: Fix eraseblock read speed miscalculation for lower partition sizes
While calculating speed during  mtd_speedtest, the time interval
(i.e., start - finish) is rounded off to the nearest milliseconds by
ignoring the fractional part. This leads to miscalculation of speed.
The miscalculation is more visible while running speed test on small
partition sizes(i.e., when partition size is equal to eraseblock size or
twice the eraseblock size) at higher spi frequencies.

For e.g., while calculating eraseblock read speed for a mtd partition with
size equal to the eraseblock size(i.e., 64KiB) the eraseblock read time
interval comes out to be 966490 nanosecond. This is then converted to
millisecond(i.e., 0.966 msec.). The integer part (i.e., 0 msec) of the
value is considered and the fractional part (i.e., 0.966) is ignored,for
calculating the eraseblock read speed. So the reported eraseblock read
speed is 0 KiB/s, which is incorrect.

There are two approaches to fix this issue.

First approach will be to keep the time interval in millisecond. and round
up the integer value, with this approach the 0.966msec time interval in the
above example will be rounded up to 1msec and this value is used for
calculating the speed. Downside of this approach is that the reported speed
is still not accurate.

Second approach will be to convert the time interval to microseconds
instead of milliseconds, with this approach the 966490 nanosecond time
interval in the above example will be converted t0 966.490usec and this
value is used for calculating the speed. As compared to the current
implementation and the suggested First approach, this approach will report
a more accurate speed. Downside of this approach is that, in future if the
mtd size is too large then the u64 variable, that holds the number of
bytes, might overflow.

In this patch we have gone with the second approach as this reports a more
accurate speed. With this approach the eraseblock read speed in the above
example comes out to be 132505 KiB/s when the spi clock is configured at
150Mhz.

fecbd4a317 mtd: rawnand: atmel: fix refcount issue in atmel_nand_controller_init
The reference counting issue happens in several error handling paths
on a refcounted object "nc->dmac". In these paths, the function simply
returns the error code, forgetting to balance the reference count of
"nc->dmac", increased earlier by dma_request_channel(), which may
cause refcount leaks.

Fix it by decrementing the refcount of specific object in those error
paths.
