	Hi all,

This patch series contains patches to add more validation of Renesas pin
control tables, and to enable compile-testing on non-Renesas platforms.
Preferably, validation is done at build time.  If not possible, it is
done at run time, when the driver is initialized, and debugging is
enabled.

Changes compared to v2:
  - Add Reviewed-by,
  - Reshuffled patches, to streamline dependencies,
  - Move initialization of func from for-condition to loop body,
  - Replace goto by break and condition check,
  - New patch "[PATCH v3 04/10] sh: sh7786: Add explicit I/O cast to
    sh7786_mm_sel()",
  - Move a change that belongs in another patch,
  - Reduce nr_enum_ids to u16, and move it into the existing padding
    hole,
  - Introduce SET_NR_ENUM_IDS() macro to reduce duplication and ifdef
    clutter.

Changes compared to v1:
  - Convert some checks from run-time to build-time checks,
  - Check relations between pin groups and functions,
  - Check PINMUX_DATA_REG() enum IDs,
  - Split run-time checks in two patches (parts before/after enum ID
    absorption), to reduce dependencies,
  - Perform run-time checks even when running on non-Renesas platforms,
  - Improve compile-test support, and move it to separate patches.

As patches 6-8 are very large, I only included the generic part of each
patch, and a sample for one particular SoC.

The full patch series is available in the topic/sh-pfc-validation-v3
branch of my git repository at
git://git.kernel.org/pub/scm/linux/kernel/git/geert/renesas-drivers.git

This has been run-tested with #define DEBUG and all pinctrl drivers
enabled.  Assembler output before/after was compared for patches 6-8.
The kbuild test robot has paid this a visit.

I plan to queue this in sh-pfc-for-v5.2.

Thanks!

Perform some basic sanity checks on all built-in pinmux tables when
DEBUG is defined, to help catching bugs early.

For now the following checks are included:
  - Check register and field widths in descriptors for config registers
    with variable-width fields,
  - Check relations between pin groups and functions:
      - All pin functions must refer to existing pin groups,
      - All pin groups must be referred to by a pin function,
      - Warn if a pin group is referred to by multiple pin functions
	(which is OK for backwards-compatibility aliases),
  - Provide suggestions for reducing table sizes: reserved fields of
    more than 3 bits can better be split in smaller subfields, as the
    storage need is proportional to the square of the width of the
    (sub)field,

Note that a dummy non-matching entry is added to the DT match table for
checking r8a7795es1_pinmux_info, as R-Car H3 ES1.0 is matched using
soc_device_match() in r8a7795_pinmux_init(), instead of by the DT match
table.

v3:
  - Add Reviewed-by,
  - Move initialization of func from for-condition to loop body,
  - Replace goto by break and condition check,

v2:
  - Drop RFC state,
  - Drop validation of fixed-with config register fields, as this is now
    done at build time,
  - Check relations between pin groups and functions,
  - Move compile-test support out,
  - Move checks depending on enum ID absorption out,
  - Move call to sh_pfc_check_driver() from sh_pfc_probe() to
    sh_pfc_init(), so the checks are even performed on non-native
    platforms when compile-testing.

Pinctrl drivers for SuperH platforms use legacy function GPIOs.
Currently this support is compiled in based on the SUPERH platform
dependency, which hinders the introduction of compile-testing support
for the affected pinctrl drivers.

Introduce a new Kconfig symbol PINCTRL_SH_FUNC_GPIO, which is
auto-selected when needed.  This symbol in turn selects
PINCTRL_SH_PFC_GPIO, to reduce the number of per-driver selects.

Source files using -Exxx error codes should include <linux/errno.h>.
On ARM, this header file is included indirectly; on SuperH, it is not,
leading to "error: ‘EINVAL’ undeclared" failures when enabling
compile-testing later.

When compile-testing on arm:

    arch/sh/include/cpu-sh4/cpu/sh7786.h: In function ‘sh7786_mm_sel’:
    arch/sh/include/cpu-sh4/cpu/sh7786.h:135:21: warning: passing argument 1 of ‘__raw_readl’ makes pointer from integer without a cast [-Wint-conversion]
      return __raw_readl(0xFC400020) & 0x7;
			 ^~~~~~~~~~
    In file included from include/linux/io.h:25:0,

		     from drivers/pinctrl/sh-pfc/pfc-sh7786.c:15:
    arch/arm/include/asm/io.h:113:21: note: expected ‘const volatile void *’ but argument is of type ‘unsigned int’
     #define __raw_readl __raw_readl

     static inline u32 __raw_readl(const volatile void __iomem *addr)
		       ^~~~~~~~~~~

__raw_readl() on SuperH is a macro that casts the passed I/O address to
the correct type, while the implementations on most other architectures
expect to be passed the correct pointer type.

Add an explicit cast to fix this.

Note that this also gets rid of a sparse warning on SuperH:

    arch/sh/include/cpu-sh4/cpu/sh7786.h:135:16: warning: incorrect type in argument 1 (different base types)
    arch/sh/include/cpu-sh4/cpu/sh7786.h:135:16:    expected void const volatile [noderef] <asn:2>*<noident>
    arch/sh/include/cpu-sh4/cpu/sh7786.h:135:16:    got unsigned int

As this is a dependency for sh-pfc compile-testing, I intend to queue
this up in sh-pfc-for-v5.2.

Enable compile-testing of all Renesas SuperH and ARM pin control
drivers, in a similar way as was done before for clock and SoC drivers
in commits 371dd373c6edd557 ("clk: renesas: Allow compile-testing of all
(sub)drivers") and 8be381a131c29c47 ("soc: renesas: Rework Kconfig and
Makefile logic").

The SuperH pin control drivers need specific include files, hence make
sure they are always found when compile-testing.

v3:
  - No changes,

v2:
  - Add proper COMPILE_TEST support, instead of just enabling all
    drivers unconditionally,
  - Drop RFC state.

Currently the PINMUX_CFG_REG() macro must be followed by initialization
data, specifying all enum IDs.  Hence the macro itself does not know
anything about the enum IDs, preventing the macro from performing any
validation on it.

Make the macro accept the enum IDs as a parameter, and update all users.
Note that array data enclosed by curly braces cannot be passed to a
macro as a parameter, hence the enum IDs are wrapped using a new macro
GROUPS().

No functional changes.

Currently the PINMUX_CFG_REG_VAR() macro must be followed by
initialization data, specifying all enum IDs.  Hence the macro itself
does not know anything about the enum IDs, preventing the macro from
performing any validation on it.

Make the macro accept the enum IDs as a parameter, and update all users.
Note that array data enclosed by curly braces cannot be passed to a
macro as a parameter, hence both the register field widths and the enum
IDs are wrapped using the GROUP() macro.

No functional changes.

Currently the PINMUX_DATA_REG() macro must be followed by initialization
data, specifying all enum IDs.  Hence the macro itself does not know
anything about the enum IDs, preventing the macro from performing any
validation on it.

Make the macro accept the enum IDs as a parameter, and update all users.
Note that array data enclosed by curly braces cannot be passed to a
macro as a parameter, hence the enum IDs are wrapped using the GROUP()
macro.

No functional changes.

This patch is incomplete!
It contains only the generic and r8a73a4 parts.

v3:
  - No changes,

v2:
  - New.

This helps catching bugs early.

Add a run-time check to the PINMUX_CFG_REG_VAR() macro, to ensure the
number of provided enum IDs is correct.  This cannot be done at build
time, as the number of values depends on the variable-width fields in
the config register.

This helps catching bugs early.
