This adds SDHCI_AM654_QUIRK_DISABLE_HS400 quirk which shall be used
to disable HS400 support. AM62P SR1.0 and SR1.1 do not support HS400
due to errata i2458 [0] so disable HS400 for these SoC revisions.

During SD suspend/resume without a full card rescan (when using
non-removable SD cards for rootfs), the SD card initialization may fail
after resume. This occurs because, after a host controller reset, the
card detect logic may take time to stabilize due to debounce logic.
Without waiting for stabilization, the host may attempt powering up the
card prematurely, leading to command timeouts during resume flow.
Add sdhci_arasan_set_power_and_bus_voltage() to wait for the card detect
stable bit before power up the card. Since the stabilization time
is not fixed, a maximum timeout of one second is used to ensure
sufficient wait time for the card detect signal to stabilize.

Due to a flaw in the hardware design, the GL9763e replay timer frequently
times out when ASPM is enabled. As a result, the warning messages will
often appear in the system log when the system accesses the GL9763e
PCI config. Therefore, the replay timer timeout must be masked.

Runtime PM is also updated to allow some code duplication in drivers
to be eliminated going forward and to work more consistently overall
in some cases.
Apart from that, there are some driver core updates related to PM

The function prefixes for loongson2_mmc_pdata follow two naming
conventions: SoC-based and DMA-based.
First, DMA-based prefixes are the preferred choice, as they clearly
highlight differences, such as prepare_dma; however, for functions
related to SoC, such as reorder_cmd_data, it is agreed to use the
smallest SoC name as the fallback prefix, such as ls2k0500.
No functional change intended.

Calling dev_pm_domain_attach()/dev_pm_domain_detach() in bus driver
probe/remove functions can affect system behavior when the drivers
attached to the bus use devres-managed resources. Since devres actions
may need to access device registers, calling dev_pm_domain_detach() too
early, i.e., before these actions complete, can cause failures on some
systems. One such example is Renesas RZ/G3S SoC-based platforms.
If the device clocks are managed via PM domains, invoking
dev_pm_domain_detach() in the bus driver's remove function removes the
device's clocks from the PM domain, preventing any subsequent
pm_runtime_resume*() calls from enabling those clocks.
The second argument of dev_pm_domain_attach() specifies whether the PM
domain should be powered on during attachment. Likewise, the second
argument of dev_pm_domain_detach() indicates whether the domain should be
powered off during detachment.
Upcoming changes address the issue described above (initially for the
platform bus only) by deferring the call to dev_pm_domain_detach() until
after devres_release_all() in device_unbind_cleanup(). The detach_power_off
field in struct dev_pm_info stores the detach power off info from the
second argument of dev_pm_domain_attach().
Because there are cases where the device's PM domain power-on/off behavior
must be conditional (e.g., in i2c_device_probe()), the patch introduces
PD_FLAG_ATTACH_POWER_ON and PD_FLAG_DETACH_POWER_OFF flags to be passed
to dev_pm_domain_attach().
Finally, dev_pm_domain_attach() and its users are updated to use the newly
introduced PD_FLAG_ATTACH_POWER_ON and PD_FLAG_DETACH_POWER_OFF macros.
This change is preparatory.

Many mobile phones feature multi-card tray designs, where the same
tray is used for both SD and SIM cards. If the SD card is placed
at the outermost location in the tray, the SIM card may come in
contact with SD card power-supply while removing the tray, possibly
resulting in SIM damage.
To prevent that, make sure the SD card is really inserted by reading
the Card Detect pin state. If it's not, turn off the power in
sdhci_msm_check_power_status() and also set the BUS_FAIL power state
on the controller as part of pwr_irq handling for BUS_ON request.

It has turned out the trying to strictly conform to the SDHCI specification
is causing problems. Let's revert and start over.

The MMC/SDHCI controller implemented by Mobileye needs the preset value
quirks to configure the clock properly at speed slower than HS200.
It otherwise works as a standard sd4hc controller.

Clang warns (or errors with CONFIG_WERROR=y):
drivers/mmc/host/rtsx_usb_sdmmc.c:1042:2: error: unannotated fall-through between switch labels [-Werror,-Wimplicit-fallthrough]
1042 | case MMC_POWER_UNDEFINED:
| ^
drivers/mmc/host/rtsx_usb_sdmmc.c:1042:2: note: insert 'break;' to avoid fall-through
1042 | case MMC_POWER_UNDEFINED:
| ^
| break;
Clang is a little more pedantic than GCC, which does not warn when
falling through to a case that is just break or return. Clang's version
is more in line with the kernel's own stance in deprecated.rst, which
states that all switch/case blocks must end in either break,
fallthrough, continue, goto, or return. Add the missing break to silence
the warning.

To conform with SD spec definition, that the host must provide at least 74
clocks before issuing first command, let's add these clock cycles at
MMC_POWER_UP.

It's only at MMC_POWER_OFF and at MMC_POWER_UP when some operations must be
carried out in sd_set_power_mode(). The code is a bit obfuscated in this
regards. Let's convert it into a switch-case-clause to make this clear.

The sdmmc_set_ios() is the only caller of sd_set_power_mode() and it
ignores the return code. Let's therefore convert sd_set_power_mode() into a
void function instead.

In the error path of sd_set_power_mode() we don't update host->power_mode,
which could lead to an imbalance of the runtime PM usage count. Fix this by
always updating host->power_mode.

This host controller is possible to change incorrect tap if an SDIO
card is used because DAT1 is used for interrupt signal on SDIO standard
but the controller doesn't take care of it. So, in the worst case,
this behavior causes a CRC error.
To resolve the issue, this driver uses manual correction mode instead
of auto correction if an SDIO card is used. Also, even if DAT1 is
mismatched on an SDIO card, this driver will not change the TAP.
