[PATCH v2 0/2] gpio: ixp4xx: Handle external clock output

[Linus Walleij <linus.walleij@xxxxxxxxxx>]

The GPIO block on the very legacy IXP4xx GPIO can provide
a generated clock output on GPIO 14 and GPIO 15. This
provides a straight-forward solution with a flag for each
clock output.

More complicated solutions are thinkable, but I deemed them
overdesigned for this legacy SoC.

Changes in v2:
- Fixed formatting pipe | in bindings
- Fixed som blank lines in bindings
- When we will just blank out the clock register settings,
  don't spend time reading the initial value.
- Link to v1: https://lore.kernel.org/r/20230921-ixp4xx-gpio-clocks-v1-0-574942bf944a@xxxxxxxxxx
