The structure of the NVIDIA Tegra234 common pinmux schema doesn't work
for restricting properties because a child node schema can't be extended
with additional properties from another schema defining the same child
node. The 2 child node schemas are evaluated independently as the
schemas are not recursively combined in any way.

As the common schema is almost all the child node schema anyways, just
remove the parent node from the common schema. Then add 'reg' and adjust
the $ref's in the users of the common schema.

Add the missing port pins P19 to P28 for RZ/Five SoC. These additional
pins provide expanded capabilities and are exclusive to the RZ/Five SoC.

Couple of port pins have different configuration and are not identical for
the complete port so introduce struct rzg2l_variable_pin_cfg to handle
such cases and introduce the PIN_CFG_VARIABLE macro. The actual pin config
is then assigned in rzg2l_pinctrl_get_variable_pin_cfg().

Add an additional check in rzg2l_gpio_get_gpioint() to only allow GPIO pins
which support interrupt facility.

While at define RZG2L_GPIO_PORT_PACK() using RZG2L_GPIO_PORT_SPARSE_PACK().

Update the gpio-ranges property in the RZ/Five SoC DTSI, as it must
match the driver.

Currently we assume all the port pins are sequential ie always PX_0 to
PX_n (n=1..7) exist, but on RZ/Five SoC we have additional pins P19_1 to
P28_5 which have holes in them, for example only one pin on port19 is
available and that is P19_1 and not P19_0. So to handle such cases
include pinmap for each port which would indicate the pin availability
on each port. As the pincount can be calculated based on pinmap drop this
from RZG2L_GPIO_PORT_PACK() macro.

Previously we had a max of 7 pins on each port but on RZ/Five Port-20
has 8 pins, so move the single pin configuration to BIT(63).

If the number of provided enum IDs in a variable width config register
description does not match the expected number, the checker uses the
expected number for validating the individual enum IDs.

However, this may cause out-of-bounds accesses on the array holding the
enum IDs, leading to bogus enum_id conflict warnings.  Worse, if the bug
is an incorrect bit field description (e.g. accidentally using "12"
instead of "-12" for a reserved field), thousands of warnings may be
printed, overflowing the kernel log buffer.

Fix this by limiting the enum ID check to the number of provided enum
IDs.

Commit d3aaa720 ("pinctrl: renesas: rzg2l: Add pin configuration
support for pinmux groups") introduced the possibility to parse pin
configuration for pinmux groups. It did that by calling
rzg2l_map_add_config() at the end of rzg2l_dt_subnode_to_map() and
jumping to the remove_group label in case rzg2l_map_add_config() failed.
But if that happens, the mutex will already be unlocked, thus this it will
lead to double mutex unlock operation. To fix this move the
rzg2l_map_add_config() call just after all the name argument is ready and
before the mutex is locked. There is no harm in doing this, as this only
parses the data from device tree that will be further processed by
pinctrl core code.

Compatible string doesn't really match with compatible string listed in the
driver itself. While binding was converted from txt to yaml
xlnx,zynq-pinctrl was listed as compatible string but example was using
xlnx,pinctrl-zynq and also this string is used in all DTSes.
xlnx,zynq-pinctrl is used only in dt binding and not present in any DT
which is stable for quite a long time that's why use old compatible string
and update binding document instead of starting to use unused compatible
string.

As noted in the "Deprecated Interfaces, Language Features, Attributes,
and Conventions" documentation [1], size calculations (especially
multiplication) should not be performed in memory allocator (or similar)
function arguments due to the risk of them overflowing. This could lead
to values wrapping around and a smaller allocation being made than the
caller was expecting. Using those allocations could lead to linear
overflows of heap memory and other misbehaviors.

So, use the purpose specific devm_kcalloc() function instead of the
argument size * count in the devm_kzalloc() function.
