Subject: [PATCH v2 0/2] gpio: ixp4xx: Handle external clock output
Date: Fri, 22 Sep 2023 08:07:55 +0200	[thread overview]
Message-ID: <20230922-ixp4xx-gpio-clocks-v2-0-0215ee10976d@linaro.org> (raw)

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@linaro.org
