MMC_SDHCI_ESDHC_IMX requires ARCH_MXC despite also being used on
ARCH_S32, which results in unmet dependencies when compiling strictly
for ARCH_S32. Resolve this by adding ARCH_S32 as an alternative to
ARCH_MXC in the driver's dependencies.

On Xilinx/AMD platforms, the CD stable bit take slightly longer than
one second(about an additional 100ms) to assert after a host
controller reset. Although no functional failure observed with the
existing one second delay but to ensure reliable initialization, increase
the CD stable timeout to 2 seconds.

CQHCI_SSC1.CIT indicates to the CQE the polling period to use for
periodic SEND_QUEUE_STATUS (CMD13) polling. Some eMMCs have only one
hardware queue, and CMD13 can only query one slot at a time for data
transmission, which cannot be processed in parallel. Modifying the
CMD13 query interval can increase the query frequency and improve
random write performance.

Enabling CMDQ support can lead to random occurrences of the error log when
there are RPMB access and data flush executed:
"mmc2: Timeout waiting for hardware interrupt."
Enabling CMDQ and then issuing a DCMD as the final command before disabling
it causes the eMMC controller to auto-gate its internal clock. Chip simulation
shows this results in a state machine mismatch after CMDQ mode exit, triggering
data-timeout errors for all subsequent read and write operations.
Therefore, the auto-clock-gate function must be disabled whenever CMDQ is
enabled.

Commit 27e8fe0da3b7 ("mmc: sdhci-of-dwcmshc: Prevent stale command
interrupt handling") clears pending interrupts when resetting
host->pending_reset to ensure no pending stale interrupts after
sdhci_threaded_irq restores interrupts. But this fix is only added for
th1520 platforms, in fact per my test, this issue exists on all
dwcmshc users, such as cv1800b, sg2002, and synaptics platforms.
So promote the above reset handling from th1520 to ip level. And keep
reset handling on rk, sg2042 and bf3 as is, until it's confirmed that
the same issue exists on these platforms too.

According to the hardware programming guide, the clock frequency must
remain below 52MHz during the transition to HS400 mode.
However,in the current implementation, the timing is set to HS400 (a
DDR mode) before adjusting the clock. This causes the clock to double
prematurely to 104MHz during the transition phase, violating the
specification and potentially resulting in CRC errors or CMD timeouts.
This change ensures that clock doubling is avoided during intermediate
transitions and is applied only when the card requires a 200MHz clock
for HS400 operation.

When I added command queue engine (CQE) support for the Rockchip eMMC
controller, I missed that RK3576 has a separate platform data struct.
While things are working fine on RK3588 (I tested the ROCK 5B) and
the suspend issue is fixed on the RK3576 (I tested the Sige5), this
results in stability issues. By also adding the necessary hooks for
the RK3576 platform the following problems can be avoided:

Add suspend/resume hooks which assert/deassert the reset signals, along
with forcing runtime suspend/resume. This allows using the driver in
scenarios where the resume is done with the help of bootloader and the
bootloader disables the SDHI clocks, resets, IRQs before passing execution
to Linux.

The meson-mx-sdio (and mmc core) only support one MMC/SD/SDIO slot
(device) per host. Thus having multiple mmc-slot nodes (one for the up
to three supported slots with one device each on the meson-mx-sdio
hardware) can be problematic.
Allow specifying all slots (with their respective device) connected to
the meson-mx-sdio hardware in device-tree, while making sure that only
the enabled one(s) are actually considered by the driver.

Use modern common clock framework helpers for simplifying the clock
controller management:
- switch to struct clk_hw for internal clocks and only get the
"cfg_div_clk" (which has to be managed at runtime) as struct clk
using devm_clk_hw_get_clk() which is then the only clock used by
struct meson_mx_mmc_host.
- use CLK_HW_INIT_FW_NAME and CLK_HW_INIT_HW helper macros for simpler
init data initialization
- keep the clock controller memory allocation separate to prevent a
potential use-after-free because struct meson_mx_mmc_host_clkc is
free'd before controller_dev

Currently if a user enqueues a work item using schedule_delayed_work() the
used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use
WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to
schedule_work() that is using system_wq and queue_work(), that makes use
again of WORK_CPU_UNBOUND.
This lack of consistency cannot be addressed without refactoring the API.
alloc_workqueue() treats all queues as per-CPU by default, while unbound
workqueues must opt-in via WQ_UNBOUND.
This default is suboptimal: most workloads benefit from unbound queues,
allowing the scheduler to place worker threads where they’re needed and
reducing noise when CPUs are isolated.
This continues the effort to refactor workqueue APIs, which began with
the introduction of new workqueues and a new alloc_workqueue flag in:
commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq")
commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag")
This change adds a new WQ_PERCPU flag to explicitly request
alloc_workqueue() to be per-cpu when WQ_UNBOUND has not been specified.
With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND),
any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND
must now use WQ_PERCPU.
Once migration is complete, WQ_UNBOUND can be removed and unbound will
become the implicit default.

This adds CQE support for the Rockchip RK3588 and RK3576 platform. To
be functional, the eMMC device-tree node must have a 'supports-cqe;'
flag property.
As the RK3576 device-tree has been upstreamed with the 'supports-cqe;'
property set by default, the kernel already tried to use CQE, which
results in system hang during suspend. This fixes the issue.

some constraints on khubepaged's collapsing of anon VMAs. It also
increases the success rate of MADV_COLLAPSE against an anon vma
- "mm: do not assume file == vma->vm_file in compat_vma_mmap_prepare()"
from Lorenzo Stoakes moves us further towards removal of
file_operations.mmap(). This patchset concentrates upon clearing up
the treatment of stacked filesystems

It's no longer required to use nth_page() when iterating pages within a
single SG entry, so let's drop the nth_page() usage.

sdhci_set_ios_common() into sdhci_set_ios()
The sdhci_set_clock() is called in sdhci_set_ios_common() and
__sdhci_uhs2_set_ios(). According to Section 3.13.2 "Card Interface
Detection Sequence" of the SD Host Controller Standard Specification
Version 7.00, the SD clock is supplied after power is supplied, so we only
need one in __sdhci_uhs2_set_ios(). Let's move the code related to setting
the clock from sdhci_set_ios_common() into sdhci_set_ios() and modify
the parameters passed to sdhci_set_clock() in __sdhci_uhs2_set_ios().

For Qualcomm SoCs which needs level shifter for SD card, extra delay is
seen on receiver data path.
To compensate this delay enable tuning for SDR50 mode for targets which
has level shifter. SDHCI_SDR50_NEEDS_TUNING caps will be set for targets
with level shifter on Qualcomm SOC's.
