The most accepted style for the array terminator is to use a single
space between the curly braces and no trailing comma. Also don't use a comma
directly before a closing brace in the other entries.

Named initializers are better readable and more robust to changes of the
struct definition. This robustness is relevant for a planned change to
struct platform_device_id replacing .driver_data by an anonymous unit.

Before commit 14dbe186b9d4 ("pinctrl: msmgpio: Make the irqchip immutable")
msm gpio irqchip conditionally initialized pctrl->irq_chip.irq_eoi to
irq_chip_eoi_parent() only for the GPIO irqs having a wakeup capable irq.
In order to make gpio irqchip immutable pctrl->irq_chip.irq_eoi is
initialized to msm_gpio_irq_eoi() which now gets invoked for both wake up
and non-wakeup capable GPIO IRQs.
Replace open coded eoi call to parent irqchip with irq_chip_eoi_parent().
Since the irq_chip_*_parent() APIs internally do not check the valid parent
data is present to ensure irq_chip_eoi_parent() is only invoked for wakeup
capable GPIOs validate d->parent_data within msm_gpio_irq_eoi().
For non wakeup capable GPIOs d->parent_data will be NULL since parent
irqchip diconnects hierarchy using irq_domain_disconnect_hierarchy() and
later irq framework trims hierarchy using irq_domain_trim_hierarchy() which
makes d->parent_data as NULL.
No functional impact.

This reverts commit 3812a9e84265a5cdd90d29fe8d97a023e91fb945.
The probe ordering fix in the following patch ensures amd_gpio_probe()
completes before i2c-designware probes AMDI0010:02, allowing the
existing amd_gpio_irq_enable() flow to work correctly. The manual IRQ
restoration added by this patch is therefore no longer needed.

In cxl_cancel_auto_attach(), it assumes cxled->pos is a valid index for
accessing p->targets[]. However, cxled->pos can be set to negative errno
in cxl_region_sort_targets() if cxl_calc_interleave_pos() fails. This
causes the driver to use a negative index to access p->targets[],
resulting in out-of-bounds access.
Fix it by walking p->targets[] instead of using cxled->pos directly.

The remoteproc framework has capability to start (or attach to) the remote
processor automatically if auto boot flag is set by the driver during
probe. If the 'firmware-name' property is available for the remoteproc
node, then that firmware will be loaded and started during auto boot. If
the remote core is started by the bootloader then during auto-boot
remoteproc framework will try to attach to the remote processor.
The current architecture allocates and adds the remoteproc instance before
all the hardware such as sram, mbox, TCM is initialized. This design has
to be changed for auto boot to work. So, rename zynqmp_r5_rproc_add()
function to zynqmp_r5_rproc_alloc() and move adding the remoteproc
instance at the end of cluster initialization. This makes sure that all
the required hardware is initialized before starting the remote
processor.

Sashiko reported an inconsistent use of NULL vs ERR_PTR()
returns in the stub helpers in xynos-acpm-protocol.h.
Since this only happens on dead code for COMPILE_TEST=y, this is not
really a bug though. Having stub functions that return NULL is a common
way to define optional interfaces, where callers still work when the
feature is disabled, though this clearly does not work for acpm because
some callers have a NULL pointer dereference when compile testing.
Since CONFIG_EXYNOS_ACPM_PROTOCOL already supports compile-testing itself,
and all (both) drivers using it clearly require the support, so this
just simplifies the option space without losing any build coverage.
Remove the stub functions entirely and adjust the one Kconfig
dependency to require EXYNOS_ACPM_PROTOCOL unconditionally.

Introduce devm_acpm_get_by_phandle() to standardize how consumer
drivers acquire a handle to the ACPM IPC interface. Enforce the
use of the "samsung,acpm-ipc" property name across the SoC and
simplify the boilerplate code in client drivers.
The first consumer of this helper is the Exynos ACPM Thermal Management
Unit (TMU) driver. The TMU utilizes a hybrid management approach: direct
register access from the Application Processor (AP) is restricted to the
interrupt pending (INTPEND) registers for event identification.
High-level functional tasks, such as sensor initialization, threshold
programming, and temperature reads, are delegated to the ACPM firmware
via this IPC interface.

Replace the embedded `struct acpm_ops` inside `struct acpm_handle` with
a pointer to a `const struct acpm_ops`.
Previously, the operations structure was embedded directly within the
handle and populated dynamically at runtime via `acpm_setup_ops()`.
This resulted in mutable function pointers and unnecessary per-instance
memory overhead.
By defining `exynos_acpm_driver_ops` statically as a `const` structure,
the function pointers are now safely housed in the read-only `.rodata`
section. This improves security by preventing function pointer
overwrites, saves memory, and slightly reduces initialization overhead
in `acpm_probe()`.
Consequently, update all consumer drivers (clk, mfd) to access the
operations via the new pointer indirection (`->ops->`). Finally, fix
the previously empty kernel-doc description for the ops member to
reflect its new pointer nature.

Rename the `dvfs_ops` and `pmic_ops` members of `struct acpm_ops` to
`dvfs` and `pmic` respectively.
Since these members are housed within the `acpm_ops` structure and
utilize the `acpm_*_ops` types, the `_ops` suffix on the variable names
creates unnecessary redundancy (e.g., `handle.ops.dvfs_ops`).
This cleanup removes the stuttering, leading to cleaner consumer code.

Rename the `n_cmd` member of `struct acpm_rx_data` to `cmdcnt` to
maintain consistent nomenclature across the driver (aligning with
`txcnt`, `rxcnt`, and transfer helpers).
With the member renamed, annotate the dynamically allocated `cmd`

bounds checking.

Both the DVFS and PMIC ACPM sub-drivers implement similar local helper
functions (acpm_dvfs_set_xfer and acpm_pmic_set_xfer) to initialize the
acpm_xfer structure before sending an IPC message.
Move this logic into a single centralized helper, acpm_set_xfer(),
in the core ACPM driver to reduce boilerplate, eliminate code
duplication, and prepare for the upcoming ACPM TMU helper sub-driver
which will also utilize this method.
Note that there is no change in underlying functionality. While the old
acpm_pmic_set_xfer() unconditionally assigned the RX buffer parameters
(xfer->rxd and xfer->rxcnt), the new unified helper introduces a
'response' boolean. All updated PMIC call sites now explicitly pass
'true' for this argument. This ensures the unified helper takes the
'if (response)' branch, performing the exact same assignments and
preserving the original PMIC behavior.

The ring_size field in struct dw_mci is misleadingly named.
Despite its name, it does not represent the size of the descriptor
ring buffer in bytes, but rather the number of descriptors allocated
within the fixed-size ring buffer.
The actual ring buffer size is fixed at PAGE_SIZE (or DESC_RING_BUF_SZ,
which equals PAGE_SIZE). Within this buffer, we allocate either
struct idmac_desc or struct idmac_desc_64addr descriptors, and
ring_size stores the count of these descriptors.
This naming has caused confusion, as it's also used to set
mmc->max_segs (the maximum number of scatter-gather segments),
which logically corresponds to the number of descriptors, not a
size in bytes.
No functional change is introduced by this naming-only patch.

I met one suspend/resume issue with sdr104 capable sdio wifi card (with
"keep-power-in-suspend" set in DT property):
After resuming from suspend to ram, the sdio wifi card stops working.
Further debug shows that although ios shows the sdio card is at sdr104
mode, the voltage is still at 3V3. This is due to missing the calling
of ->start_signal_voltage_switch() in sdhci_resume_host().
Fix this issue by adding ->start_signal_voltage_switch() in
sdhci_resume_host(). This also matches what we do for
sdhci_runtime_resume_host().
Then the question is: why this issue hasn't reported and fixed for so
long time. IMHO, several reasons: Some host controllers just kick off
the runtime resume for system resume, so they benefit from the well
supported runtime pm code; Some platforms just use the old sdio wifi
card which doesn't need signal voltage switch at all, the default
voltage is 3v3 after resuming.

During the SSR/PDR down notification the tx_lock is taken with the
intent to provide synchronization with active DMA transfers.
But during this period qcom_slim_ngd_down() is invoked, which ends up in
slim_report_absent(), which takes the slim_controller lock. In multiple
other codepaths these two locks are taken in the opposite order (i.e.
slim_controller then tx_lock).
The result is a lockdep splat, and a possible deadlock:
rprocctl/449 is trying to acquire lock:
ffff00009793e620 (&ctrl->lock){+.+.}-{4:4}, at: slim_report_absent (drivers/slimbus/core.c:322) slimbus
but task is already holding lock:
ffff00009793fb50 (&ctrl->tx_lock){+.+.}-{4:4}, at: qcom_slim_ngd_ssr_pdr_notify (drivers/slimbus/qcom-ngd-ctrl.c:1475) slim_qcom_ngd_ctrl
which lock already depends on the new lock.
Possible unsafe locking scenario:
CPU0 CPU1
---- ----
lock(&ctrl->tx_lock);
lock(&ctrl->lock);
lock(&ctrl->tx_lock);
lock(&ctrl->lock);
The assumption is that the comment refers to the desire to not call
qcom_slim_ngd_exit_dma() while we have an ongoing DMA TX transaction.
But any such transaction is initiated and completed within a single
qcom_slim_ngd_xfer_msg().
Prior to calling qcom_slim_ngd_exit_dma() the slim_controller is torn
down, all child devices are notified that the slimbus is gone and the
child devices are removed.
Stop taking the tx_lock in qcom_slim_ngd_ssr_pdr_notify() to avoid the
deadlock.

The work structs and work queue are controller resources, create and
destroy them in the controller context. Creating them as part of the
child device's probe path seems to be okay now that the controller's
probe has been updated, but if for some reason the child does not probe
successfully a SSR or PDR notification will schedule_work() on an
uninitialized "ngd_up_work".
Move the initialization of these controller resources to the controller
probe function to avoid any issues, and to clarify the ownership.

When the remoteproc starts in parallel with the NGD driver being probed,
or the remoteproc is already up when the PDR lookup is being registered,
or in the theoretical event that we get an interrupt from the hardware,
these callbacks will operate on uninitialized data. This result in
issues to boot the affected boards.
One such example can be seen in the following fault, where
qcom_slim_ngd_ssr_pdr_notify() schedules work on the NULL ngd_up_work.

The really old controllers (rk2928, rk3066, rk3188) do not support UHS
speeds at all, and thus never handled phase data.
For that reason it never had a parse_dt callback and no driver private
data at all.
Commit ff6f0286c896 ("mmc: dw_mmc-rockchip: Add memory clock auto-gating
support") makes the private data sort of mandatory, because the init
function checks whether phases are configured internally or through the
clock controller.
This results in the old SoCs then experiencing NULL-pointer dereferences
when they try to access that private-data struct.
While we could have if (priv) conditionals in all places, it's way less
cluttery to just give the old types their private-data struct.

Platform devices created with platform_device_alloc() call
platform_device_release() when the last reference to the device's
kobject is dropped. This function calls of_node_put() unconditionally.
This works fine for devices created with platform_device_register_full()
but users of the split approach (platform_device_alloc() +
platform_device_add()) must bump the reference of the of_node they
assign manually. Add the missing call to of_node_get().
