Subject: [PATCH v4 00/13] gpiolib: Two new helpers and way toward fwnode
Date: Fri,  1 Apr 2022 13:35:51 +0300	[thread overview]
Message-ID: <20220401103604.8705-1-andriy.shevchenko@linux.intel.com> (raw)

This is a spin-off of the previous work of switching GPIO library
to use fwnode instead of of_node. Here we introduce a couple of
a new macro helpers, which allows to switch some of the drivers
to use fwnode and partially fwnode APIs. As a result of this cleanup
a few drivers switched to use GPIO fwnode instead of of_node.

Bart, Linus, I can take it thru my tree with an immutable branch if
it's the way you prefer, otherwise please suggest on how to proceed.

Changelog v4:
- fixed compilation of the Samsung pin control drivers (LKP)
- explained in the commit message why namespacing is good for meson defs
- added tag to one of meson patches (Neil)

Changelog v3:
- moved count initialization to the definition in patch 2 (Geert)
- replaced of_args by args, used %pfwP in patch 7 (Geert)
- fixed kernel doc warning in patch 7
- added tags to patches 1, 2, 6, and 7 (Geert)
- added tag to patch 4 (Fabien)
- renamed MREG to MESON_REG in patch 9 (Neil)
- added tag to patch 10 (Neil)
- used --base for cover-letter

Changelog v2:
- properly based, so kbuild bot may test it (LKP)
- fixed typo in the macro (Geert)
- split to two macro helpers and rename the gpiochip_count()
- tagged one of stm32 and one of meson patches (Fabien, Neil)
- unified previously standalone armada patch
- due to above rewrote the armada patch from v1 completely (Sergey)
- added a lot of a new patches
- compile tested all of them on x86
