[PATCH v5 00/13] pinctrl: Convert struct group_desc to use struct pingroup

[PATCH v5 00/13] pinctrl: Convert struct group_desc to use struct pingroup

[Andy Shevchenko]

The struct group_desc has a lot of duplication with struct pingroup.
Deduplicate that by embeddind the latter in the former and convert
users.

NB. The function_desc is in plan to follow the similar deduplication.

This time test-compiled with old GCC 8 for arm64, besides GCC 13 and
LLVM 16 for x86_64.

In v5:
- dropped applied patches
- elaborated the need of the conversion (Fabio)
- reworked to avoid build errors on old GCC (Marek, Krzysztof, Geert)

v4: https://lore.kernel.org/r/20231129161459.1002323-1-andriy.shevchenko@linux.intel.com

In v4:
- made pins also unsigned in struct group_desc (Geert)
- made local pins variable unsigned in renesas drivers (Geert)
- collected more tags (Paul, Geert)

v3: https://lore.kernel.org/r/20231128200155.438722-1-andriy.shevchenko@linux.intel.com

In v3:
- fixed reported bug in equilibrium code (LKP)                                                                   - collected tags (Emil, Florian, Paul)

v2: https://lore.kernel.org/r/20231123193355.3400852-1-andriy.shevchenko@linux.intel.com

In v2:
- added a few patches to fix multiple compile-time errors (LKP)
- added tag (Jonathan)

v1: https://lore.kernel.org/r/20231122164040.2262742-1-andriy.shevchenko@linux.intel.com

[Andy Shevchenko]

struct group_desc is a particular version of the struct pingroup
with associated opaque data. Start switching pin control core and
drivers to use it explicitly.

[PATCH v5 09/13] pinctrl: keembay: Convert to use grp member

[Andy Shevchenko]

Convert drivers to use grp member embedded in struct group_desc,
because other members will be removed to avoid duplication and
desynchronisation of the generic pin group description.

This INGENIC_PIN_GROUP() macro doesn't need to be modified, does it?

We can go either way. I prefer to go this way as it reduces level of
indirections in the macros. It makes code easier to read and understand.
But if you insist, I can drop that change in next version.

I like the patches to be minimal. But I understand your point of view
as well.

If you have to issue a v6, maybe state the reason why you also modify
INGENIC_PIN_GROUP() then. But I don't care enough to request a v6 just
for that.
