pinctrl: nomadik: Dereference gpio_chip properly

The irq data passed to irc_chip handlers i the struct gpio_chip
and nothing else. We are just lucky that the nomadik chip
pointer is first in the struct. Use the proper dereferencing
and helpers.

Merge tag 'samsung-pinctrl-6.1' of https://git./linux/kernel/git/pinctrl/samsung into devel

Samsung pinctrl drivers changes for v6.1

1. Minor fix in order of initializing pinctrl driver - GPIOs should be
   configured before registering gpiolib.
2. Final steps to deprecated bindings headers with register constants.
   The constants were moved to include files in DTS directories, because
   these are not suitable for bindings.  Remove final references and
   mark binding header as deprecated to warn any users.

When the driver want to disable the signal of the function, it doesn't

Ball | Default | P0 Signal | P0 Expression               | Other
-----+---------+-----------+-----------------------------+----------
E21   GPIOG0    SD2CLK      SCU4B4[16]=1 & SCU450[1]=1    GPIOG0

B22   GPIOG1    SD2CMD      SCU4B4[17]=1 & SCU450[1]=1    GPIOG1
-----+---------+-----------+-----------------------------+----------
Assume the register status like below:
SCU4B4[16] == 1 & SCU4B4[17] == 1 & SCU450[1]==1
After the driver set the Ball E21 to the GPIOG0:
SCU4B4[16] == 0 & SCU4B4[17] == 1 & SCU450[1]==0
When the driver want to set the Ball B22 to the GPIOG1, the condition of
the SD2CMD will be false causing SCU4B4[17] not to be cleared.

pinctrl: armada-37xx: Checks for errors in gpio_request_enable callback

Now when all MPP pins are properly defined and every MPP pin has GPIO
function, always checks for errors in armada_37xx_gpio_request_enable()
function when calling armada_37xx_pmx_set_by_name(). Function
armada_37xx_pmx_set_by_name() should not return "not supported" error
anymore for any GPIO pin when requesting GPIO mode.

pinctrl: armada-37xx: Fix definitions for MPP pins 20-22

All 3 MPP pins (20, 21 and 22) can be configured individually and also can
be configured to GPIO functions. Fix definitions for these MPP pins in

pinctrl: rockchip: Add RV1126 pinctrl support

RV1126 has five GPIOs groups - GPIO0 in PD_MMU and GPIO1-4
in PD_BUS.

In GPIO0, up to Lower C group GPIO0_C[3:0] is part of PMU
but rest of the groups from there are part of GRF.

Added pinctrl support for RV1126 and the pull, drv and schmitt
calculations are inferred from [1] authored by Jianqun Xu.

dt-bindings: pinctrl: samsung: deprecate header with register constants

For convenience (less code duplication, some meaning added to raw
number), the pin controller pin configuration register values
were defined in the bindings header.  These are not some IDs or other
abstraction layer but raw numbers used in the registers

These constants do not fit the purpose of bindings.  They do not provide
any abstraction, any hardware and driver independent ID.  With minor
exceptions, the Linux drivers actually do not use the bindings header at
all.

All of the constants were moved already to headers local to DTS
(residing in DTS directory) and to Samsung pinctrl driver (where
applicable), so remove any references to the bindings header and add a
warning tha tit is deprecated.

i2c: Make remove callback return void

The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

leds: lm3601x: Improve error reporting for problems during .remove()

Returning an error value in an i2c remove callback results in a generic
error message being emitted by the i2c core, but otherwise it doesn't
make a difference. The device goes away anyhow and the devm cleanups are
called.

So instead of triggering the generic i2c error message, emit a more
helpful message if a problem occurs and return 0 to suppress the generic
message.

This patch is a preparation for making i2c remove callbacks return void.
