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.

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.

To conclude the ux500 busy timeout fixes, this improves the debug and

[ 20.493652] mmci-pl18x 80005000.mmc: no busy signalling in time CMD06
We see a lot of lost IRQs and the timeout always occur while waiting for
the end IRQ, and then the busy status is *low* meaning the busy indication
is already de-asserted.
So busy signalling is missed in various ways for various reasons,
sometimes it appears that IRQs are simply lost.
One hypothesis is that this happens because the events happen so fast
that they are transient, and since the MMCI state machine in effect is
handling an edge trigger (rising or falling signal on DAT0) the
internal logic will miss the event, because the state machine in the
hardware is sampling the line, and will at times detect only the first
event but miss the second, fireing only one IRQ.
We print the second timeout error with dev_err() since it is pretty
serious, the other events are so common and simple to handle that we
can keep them at dev_dbg() level.

Fix the above issue by changing mmc_alloc_host() to devm_mmc_alloc_host()

api takes care of freeing, also remove mmc_free_host() from remove

mmc_add_host() may return error, if we ignore its return value,
1. the memory allocated in mmc_alloc_host() will be leaked
2. null-ptr-deref will happen when calling mmc_remove_host()
in remove function spmmc_drv_remove() because deleting not
added device.
Fix this by checking the return value of mmc_add_host(). Moreover,
I fixed the error handling path of spmmc_drv_probe() to clean up.

For a completed request, after the mmc_blk_mq_complete_rq(mq, req)
function is executed, the bitmap_tags corresponding to the
request will be cleared, that is, the request will be regarded as
idle. If the request is acquired by a different type of process at
this time, the issue_type of the request may change. It further
caused the value of mq->in_flight[issue_type] to be abnormal,
and a large number of requests could not be sent.

blk_mq_free_request
blk_mq_get_request

This strategy can ensure the consistency of issue_type

au1xmmc is split somewhat awkwardly into the main mmc subsystem driver,
and callbacks in platform_data that sit under arch/mips/ and are
always built in. The latter than call mmc_detect_change through
symbol_get. Remove the use of symbol_get by requiring the driver
to be built in. In the future the interrupt handlers for card
insert/eject detection should probably be moved into the main driver,
and which point it can be built modular again.

Even if sdhci_pltfm_pmops is specified for PM, this driver doesn't apply
sdhci_pltfm, so the structure is not correctly referenced in PM functions.
This applies sdhci_pltfm to this driver to fix this issue.
- Call sdhci_pltfm_init() instead of sdhci_alloc_host() and
other functions that covered by sdhci_pltfm.
- Move ops and quirks to sdhci_pltfm_data
- Replace sdhci_priv() with own private function sdhci_f_sdh30_priv().

Conversion from big-endian to native is done in a common function
mmc_app_send_scr(). Converting in moxart_transfer_pio() is extra.
Double conversion on a LE system returns an incorrect SCR value,
leads to errors:

It has turned out that some mmc host drivers were not ready to deal with
this change. Let's fix those host drivers first, then we can give this a
new try.

Pull gpio updates from Bartosz Golaszewski:
"We have two new drivers, some improvements to the core code, lots of
different updates to existing GPIO drivers and some dt-bindings on
top.
There's nothing controversial in here and almost everything has been
in next for more than a week (95% a lot longer than this). The only
thing that has spent less time in next is a new driver so no risk of
regressions.
The single merge pulls in changes that remove all usage of global GPIO
numbers from arch/arm/mach-omap.
Core GPIO library:
- remove unused symbols
- don't spam the kernel log with messages about hogs
- remove old sysfs API cruft
- improve handling of GPIO masks
New drivers:
- add a driver for the BlueField-3 GPIO controller
- add GPIO support for the TPS65219 PMIC
Driver improvements:
- extend the gpio-aggregator driver to support ramp-up/ramp-down
delay
- remove unnecessary CONFIG_OF guards from gpio-aggregator
- readability improvements in gpio-tangier
- switch i2c drivers back to using probe() now that it's been
converted in the i2c subsystem to not taking the id parameter
- remove unused inclusions of of_gpio.h in several drivers
- make pm ops static in gpio-davinci and fix a comment
- use more devres in drivers to shrink and simplify the code
- add missing include in gpio-sa1100
- add HAS_IOPORT KConfig dependency where needed
- add permissions checks before accessing pins in gpio-tegra186
- convert the gpio-zynq driver to using immutable irqchips
- preserve output settings set by the bootloader in gpio-mpc8xxx
Selftests:
- tweak the variable naming in script tests
Device tree updates:
- convert gpio-mmio and gpio-stmpe to YAML
- add parsing of GPIO hogs to gpio-vf610
- add bindings for the Cirrus EP93xx GPIO controller
- add gpio-line-names property to the gpio-pca9570 bindings
- extend the binding for x-powers,axp209 with another block"

The ux500 variant doesn't have a HW based timeout to use for busy-end IRQs.
To avoid hanging and waiting for the card to stop signaling busy, let's
schedule a delayed work, according to the corresponding cmd->busy_timeout
for the command. If the work gets to run, let's kick the IRQ handler to
complete the currently running request/command.

This microSD card never clears Flush Cache bit after cache flush has
been started in sd_flush_cache(). This leads e.g. to failure to mount
file system. Add a quirk which disables the SD cache for this specific
card from specific manufacturing date of 11/2019, since on newer dated
cards from 05/2023 the cache flush works correctly.

It seems that Kingston EMMC04G-M627 despite advertising TRIM support does
not work when the core is trying to use REQ_OP_WRITE_ZEROES.
We are seeing I/O errors in OpenWrt under 6.1 on Zyxel NBG7815 that we did
not previously have and tracked it down to REQ_OP_WRITE_ZEROES.
Trying to use fstrim seems to also throw errors like:
[93010.835112] I/O error, dev loop0, sector 16902 op 0x3:(DISCARD) flags 0x800 phys_seg 1 prio class 2
Disabling TRIM makes the error go away, so lets add a quirk for this eMMC
to disable TRIM.
