Currently the pinctrl GPIO helpers all take a number from the global
GPIO numberspace - of which we're trying to get rid of as argument.
These helpers are almost universally called from GPIOLIB driver
callbacks which take a pointer to the backing gpio_chip and the
controller-relative offset as arguments.
Let's provide improved variants of these functions that match the
GPIOLIB signatures as the first step in removing the older flavor.

Merge tag 'gpio-updates-for-v6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio updates from Bartosz Golaszewski:
"We don't have any new drivers. The loongson driver is getting extended
with support for new models. There's a big refactor of gpio-pca953x
and many small improvements to others.
The GPIO code in the kernel has acquired a lot of cruft over the years
as well as many abusers of the API across the kernel tree. This
release cycle we have started a major cleanup and improvement effort
that will most likely span several releases. We have started by
converting external users of struct gpio_chip to accessing the wrapper
around it - struct gpio_device. This is because the latter is
reference counted while the former is removed when the provider is
unbound. We also removed several instances of drivers accessing
private GPIOLIB structures and including the private header from
drivers/gpio/.
To that end you'll see several commits aimed at different subsystems
(acked by relevant maintainers) as well as two merges from the
x86/platform tree.
We'll then rework the locking in GPIOLIB which currently uses a big
spinlock for many different things and could use becoming more
fine-grained, especially as it doesn't even get the locking right.
We'll also use SRCU for protecting the gpio_chip pointer against
in-kernel hot-unplug crashes similar to what we saw triggered from
user-space and fixed with semaphores in gpiolib-cdev. The core GPIOLIB
is still vulnerable to these use-cases. I'm just mentioning the plans
here, this is not part of this PR.
You'll see some new instances of using __free(). We've added a
gpio_device_put cleanup helper similar to the put_device one
introduced by Peter Zijlstra and used it according to the preferred
pattern except where it didn't make sense.
GPIOLIB core:
- provide interfaces allowing users to retrieve, manage and query the
reference counted GPIO device instead of accessing the private
gpio_chip structure
- replace gpiochip_find() with gpio_device_find()
- remove unused acpi_get_and_request_gpiod()

The Qualcomm LPASS LPI pin controller driver uses one lock for guarding
Read-Modify-Write code for slew rate registers. However the pin
configuration and muxing registers have exactly the same RMW code but
are not protected.
Pin controller framework does not provide locking here, thus it is
possible to trigger simultaneous change of pin configuration registers
resulting in non-atomic changes.
Protect from concurrent access by re-using the same lock used to cover
the slew rate register. Using the same lock instead of adding second
one will make more sense, once we add support for newer Qualcomm SoC,
where slew rate is configured in the same register as pin
configuration/muxing.

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
callback to the void returning variant.

RZ/G3S supports different drive strength values for different power
sources and pin groups (A, B, C). On each group there could be up to 4
drive strength values per power source. Available power sources are
1v8, 2v5, 3v3. Drive strength values are more fine tuned than what was
previously available on the driver thus the necessity of having
micro-amp support. As drive strength and power source values are linked
together the hardware setup for these was moved at the end of
rzg2l_pinctrl_pinconf_set() to ensure proper validation of the new
values.
The drive strength values are expected to be initialized though the
SoC-specific hardware configuration data structure.

On RZ/G3S PFC register allow setting 8 functions for individual ports
(function1 to function8). For function1 the register need to be
configured with 0, for function8 the register need to be configured with
7. We cannot use zero based addressing when requesting functions from
different code places as the documentation
(RZG3S_pinfunction_List_r1.0.xlsx) states explicitly that function0 is
GPIO.
Add a new member to struct rzg2l_hwcfg that will keep the offset that
needs to be substracted before applying a value to a PFC register.

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.
