Fixing this reveals many warnings including having grandchild nodes in some

pinctrl: renesas: rzn1: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove

pinctrl: renesas: rzg2l: Index all registers based on port offset
To get the address that needs to be read/written for specific port
functionalities, the P(), PM(), PMC(), PFC(), PIN(), IOLH() IEN(),
ISEL() macros are used. Some of these macros receive as argument the
hardware port identifier, some the hardware port offset address (e.g.
ISEL() received port identifier, IOLH() received port offset address).
This makes it hard to extend the current driver for SoCs where port
identifiers are not contiguous in the memory map of the pin controller.
This is the case for the RZ/G3S pin controller where ports are mapped as
follows:
port offset port identifier
----------- ---------------
0x20 P0
0x21 P5
0x22 P6
0x23 P11
0x24 P12
0x25 P13
0x26 P14
0x27 P15
0x28 P16
0x29 P17
0x2a P18
0x30 P1
0x31 P2
0x32 P3
0x33 P4
0x34 P7
0x35 P8
0x36 P8
0x37 P10
To make this achievable, change all the above macros used to get the
address of a port register for a specific port functionality based on
the port hardware address. Summarized, all the above macros will get as
argument the port offset address listed in the above table.
With this RZG2L_SINGLE_PIN_GET_PORT_OFFSET(),
RZG2L_PIN_ID_TO_PORT_OFFSET() and RZG2L_GPIO_PORT_GET_INDEX() were
replaced by RZG2L_PIN_CFG_TO_PORT_OFFSET(); RZG2L_SINGLE_PIN_GET_CFGS()
and RZG2L_GPIO_PORT_GET_CFGS() were replaced by RZG2L_PIN_CFG_TO_CAPS().
Also rzg2l_pinctrl_set_pfc_mode() does not need the port argument
anymore. Also rzg2l_gpio_direction_input() and
rzg2l_gpio_direction_output() do not need to translate port and bit
locally as this can be done by rzg2l_gpio_set_direction().
To use the same naming for port, bit/pin, and register offset, replace
the port_offset variable names in different places by variables named
off. There is no longer a need to initialize cfg and bit in different
code places.

Past versions of this driver have manually calculated base values for
both the pinctrl numberspace and the global GPIO numberspace, giving
both the same values. This was necessary for the global GPIO
numberspace, since its values need to be unique system-wide. However, it
was not necessary for the pinctrl numberspace, since its values only
need to be unique for a single instance of the pinctrl device. It was
just convenient to use the same values for both spaces.
Right now those calculations are only used for the pinctrl numberspace,

pinctrl: realtek: Fix error handling in probe()
There are several issues in the probe function:
1) of_iomap() return NULL on error but the code checks for error
pointers.
2) pinctrl_register() is the reverse. It returns error pointers
but the code checks for NULL.
3) The error paths need to call iounmap(data->base) before returning
to avoid a resource leak.

pinctrl: sunxi: h616: add extra gpio banks
Some SoCs from the H616 family (such as the T507) have the same die but
more output pins that are used for additional peripherals. The T507 SoC
don't have a built-in multiphy like the AC200 or AC300 connected to the
bank A. With the T507 these pins can be freely used for any other application.
This patch adds the missing muxes on banks A, D and E.
Thanks to Samuel and Andre for the review.

pinctrl: pinctrl-aspeed-g6: Add more settings for USB2AHP function
AST2600 USB2AHP (USB PortA: PCIe EHCI to PHY) function needs to set the
register SCUC20[16]. Set it to enable the PCIe EHCI device on PCIe bus.
Besides, also add USB2AHP signal expressions into pin declarations.
