Pull ARM SoC boardfile updates from Arnd Bergmann
 "Unused boardfile removal for 6.3

  This is a follow-up to the deprecation of most of the old-style board
  files that was merged in linux-6.0, removing them for good.

  This branch is almost exclusively dead code removal based on those
  annotations. Some device driver removals went through separate
  subsystem trees, but the majority is in the same branch, in order to
  better handle dependencies between the patches and avoid breaking
  bisection.

  Unfortunately that leads to merge conflicts against other changes in
  the subsystem trees, but they should all be trivial to resolve by
  removing the files.

  See commit 7d0d3fa7339e ("Merge tag 'arm-boardfiles-6.0' of
  git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc") for the
  description of which machines were marked unused and are now removed.

  The only removals that got postponed are Terastation WXL (mv78xx0) and
  Jornada720 (StrongARM1100), which turned out to still have potential
  users"

-S3C24XX GPIO Control
-====================
-
-Introduction
-------------
-
-  The s3c2410 kernel provides an interface to configure and
-  manipulate the state of the GPIO pins, and find out other
-  information about them.
-
-  There are a number of conditions attached to the configuration
-  of the s3c2410 GPIO system, please read the Samsung provided
-  data-sheet/users manual to find out the complete list.
-
-  See Documentation/arm/samsung/gpio.rst for the core implementation.
-
-
-GPIOLIB
--------
-
-  With the event of the GPIOLIB in drivers/gpio, support for some
-  of the GPIO functions such as reading and writing a pin will
-  be removed in favour of this common access method.
-
-  Once all the extant drivers have been converted, the functions
-  listed below will be removed (they may be marked as __deprecated
-  in the near future).
-
-  The following functions now either have a `s3c_` specific variant
-  or are merged into gpiolib. See the definitions in
-  arch/arm/mach-s3c/gpio-cfg.h:
-
-  - s3c2410_gpio_setpin()	gpio_set_value() or gpio_direction_output()
-  - s3c2410_gpio_getpin()	gpio_get_value() or gpio_direction_input()
-  - s3c2410_gpio_getirq()	gpio_to_irq()
-  - s3c2410_gpio_cfgpin()	s3c_gpio_cfgpin()
-  - s3c2410_gpio_getcfg()	s3c_gpio_getcfg()
-  - s3c2410_gpio_pullup()	s3c_gpio_setpull()
-
-
-GPIOLIB conversion
-------------------
-
-If you need to convert your board or driver to use gpiolib from the phased
-out s3c2410 API, then here are some notes on the process.
-
-1) If your board is exclusively using an GPIO, say to control peripheral
-   power, then it will require to claim the gpio with gpio_request() before
-   it can use it.
-
-   It is recommended to check the return value, with at least WARN_ON()
-   during initialisation.
-
-2) The s3c2410_gpio_cfgpin() can be directly replaced with s3c_gpio_cfgpin()
-   as they have the same arguments, and can either take the pin specific
-   values, or the more generic special-function-number arguments.
-
-3) s3c2410_gpio_pullup() changes have the problem that while the
-   s3c2410_gpio_pullup(x, 1) can be easily translated to the
-   s3c_gpio_setpull(x, S3C_GPIO_PULL_NONE), the s3c2410_gpio_pullup(x, 0)
-   are not so easy.
-
-   The s3c2410_gpio_pullup(x, 0) case enables the pull-up (or in the case
-   of some of the devices, a pull-down) and as such the new API distinguishes
-   between the UP and DOWN case. There is currently no 'just turn on' setting
-   which may be required if this becomes a problem.
-
-4) s3c2410_gpio_setpin() can be replaced by gpio_set_value(), the old call
-   does not implicitly configure the relevant gpio to output. The gpio
-   direction should be changed before using gpio_set_value().
-
-5) s3c2410_gpio_getpin() is replaceable by gpio_get_value() if the pin
-   has been set to input. It is currently unknown what the behaviour is
-   when using gpio_get_value() on an output pin (s3c2410_gpio_getpin
-   would return the value the pin is supposed to be outputting).
-
-6) s3c2410_gpio_getirq() should be directly replaceable with the
-   gpio_to_irq() call.
-
-The s3c2410_gpio and `gpio_` calls have always operated on the same gpio
-numberspace, so there is no problem with converting the gpio numbering
-between the calls.
-
-
-Headers
--------
-
-  See arch/arm/mach-s3c/regs-gpio-s3c24xx.h for the list
-  of GPIO pins, and the configuration values for them. This
-  is included by using #include <mach/regs-gpio.h>
-
-
-PIN Numbers
------------
-
-  Each pin has an unique number associated with it in regs-gpio.h,
-  e.g. S3C2410_GPA(0) or S3C2410_GPF(1). These defines are used to tell
-  the GPIO functions which pin is to be used.
-
-  With the conversion to gpiolib, there is no longer a direct conversion
-  from gpio pin number to register base address as in earlier kernels. This
-  is due to the number space required for newer SoCs where the later
-  GPIOs are not contiguous.
-
-
-Configuring a pin
------------------
-
-  The following function allows the configuration of a given pin to
-  be changed.
-
-    void s3c_gpio_cfgpin(unsigned int pin, unsigned int function);
-
-  e.g.:
-
-     s3c_gpio_cfgpin(S3C2410_GPA(0), S3C_GPIO_SFN(1));
-     s3c_gpio_cfgpin(S3C2410_GPE(8), S3C_GPIO_SFN(2));
-
-   which would turn GPA(0) into the lowest Address line A0, and set
-   GPE(8) to be connected to the SDIO/MMC controller's SDDAT1 line.
-
-
-Reading the current configuration
----------------------------------
-
-  The current configuration of a pin can be read by using standard
-  gpiolib function:
-
-  s3c_gpio_getcfg(unsigned int pin);
-
-  The return value will be from the same set of values which can be
-  passed to s3c_gpio_cfgpin().
-
-
-Configuring a pull-up resistor
-------------------------------
-
-  A large proportion of the GPIO pins on the S3C2410 can have weak
-  pull-up resistors enabled. This can be configured by the following
-  function:
-
-    void s3c_gpio_setpull(unsigned int pin, unsigned int to);
-
-  Where the to value is S3C_GPIO_PULL_NONE to set the pull-up off,
-  and S3C_GPIO_PULL_UP to enable the specified pull-up. Any other
-  values are currently undefined.
-
-
-Getting and setting the state of a PIN
---------------------------------------
-
-  These calls are now implemented by the relevant gpiolib calls, convert
-  your board or driver to use gpiolib.
-
-
-Getting the IRQ number associated with a PIN
---------------------------------------------
-
-  A standard gpiolib function can map the given pin number to an IRQ
-  number to pass to the IRQ system.
-
-   int gpio_to_irq(unsigned int pin);
-
-  Note, not all pins have an IRQ.
