[v13] PolarFire SoC GPIO interrupt support

[PATCH v13 0/5] PolarFire SoC GPIO interrupt support

Posted by Conor Dooley 2 weeks, 5 days ago

From: Conor Dooley <conor.dooley@microchip.com>

Yo,

Here's a v3 with an extra patch updating the gpio binding from fished
out from my old branch, fixing the examples and setting the permitted
values of gpios for the controllers on polarfire soc and the existing
binding patch's example fixed.

Bartosz, you acked the gpio driver patch, are you expecting the whole
lot to go together via the soc tree or something?

Cheers,
Conor.

v13:
- fix the binding example
- add a new binding patch

v12:
- Implemented mux driver feedback from Hervé.
- Reworked the gpio interrupt stuff per Linus' feedback, so didn't pick
  up Hervés tag.
- Modified the binding description to cover the 6 always "direct mode"
  interrupts on gpio controller 1.

Gonna interpret the ack and lack of response to me asking if the gpio
change was mine to take as it being the case.
Applied to riscv-soc-for-next, thanks!

Ah, yes sorry, your email went under my radar. Feel free to take them.

Am I to interpret this being all you applied and the driver getting an
ack as meaning I should take the driver change with the mux driver
through the soc tree?

Cheers,
Conor.
