The zynq driver can be enabled for compile-testing on builds without
CONFIG_OF, leading to a link error:

In the original implementation, krealloc() failure handling incorrectly
assigned the original memory pointer to NULL after kfree(), causing a

In sunxi_pctrl_dt_node_to_map(), when krealloc() fails to resize
the pinctrl_map array, the function returns -ENOMEM directly
without freeing the previously allocated *map buffer. This results
in a memory leak of the original kmalloc_array allocation.

Ensure only valid pins are configured by validating pin mappings before
setting the mux function.
Rename rzg2l_validate_gpio_pin() to rzg2l_validate_pin() to reflect its
broader purpose validating both GPIO pins and muxed pins. This helps
avoid invalid configurations.

As part of a wider cleanup trying to get rid of OF specific APIs, an
incorrect (and partially unrelated) cleanup was introduced.
The goal was to replace a device_for_each_chil_node() loop including an
additional condition inside by a macro doing both the loop and the
check on a single line.
The snippet:
device_for_each_child_node(dev, child)
if (fwnode_property_present(child, "gpio-controller"))
continue;
was replaced by:
for_each_gpiochip_node(dev, child)
which expands into:
device_for_each_child_node(dev, child)
for_each_if(fwnode_property_present(child, "gpio-controller"))
This change is actually doing the opposite of what was initially
expected, breaking the probe of this driver, breaking at the same time
the whole boot of Nuvoton platforms (no more console, the kernel WARN()).
Revert these two changes to roll back to the correct behavior.

On some platforms, the UFS-reset pin has no interrupt logic in TLMM but
is nevertheless registered as a GPIO in the kernel. This enables the
user-space to trigger a BUG() in the pinctrl-msm driver by running, for
example: `gpiomon -c 0 113` on RB2.
The exact culprit is requesting pins whose intr_detection_width setting
is not 1 or 2 for interrupts. This hits a BUG() in
msm_gpio_irq_set_type(). Potentially crashing the kernel due to an
invalid request from user-space is not optimal, so let's go through the
pins and mark those that would fail the check as invalid for the irq chip
as we should not even register them as available irqs.
This function can be extended if we determine that there are more
corner-cases like this.

Always descent to drivers/pinctrl/starfive/ because limiting it with
SOC_STARFIVE is redundant since its Makefile doesn't build anything if
no Starfive-specific pin control Kconfig options are enabled. This
allows compile testing on other architectures with allyesconfig.

When a pin is assigned to a coprocessor not running Linux, the pin
should be flagged in the DT as reserved and not usable by Linux.
Add pin configuration RSVD (Reserved) and instrument the driver to
not update the mux setting.

On SoC stm32mp257, GPIO supports security and isolation compliant
with the Resource Isolation Framework (RIF). Each GPIO line can be
assigned to different security and compartment domains.
Add the generic code to handle the RIF configuration set by the
secure world and initialize the GPIO valid mask accordingly.
Enable the RIF support for stm32mp257.
