[PATCH v3 00/10] pinctrl: sh-pfc: Validation and compile-testing

[Geert Uytterhoeven <geert+renesas@xxxxxxxxx>]

	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!

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
