Hello,
This patch set fixes conversion from a GPIO number to an IRQ number in the
sh-pfc driver in the device tree case.
Patches 01/10 to 05/10 clean up the driver to prepare it for the core fix in
patch 06/10. As explained in patch 06/10 commit message, on non-DT platforms
IRQ controllers associated with the GPIOs have a fixed IRQ base value known at
compile time. The sh-pfc driver translates GPIO number to IRQ numbers using a
hardcoded table. This mechanism breaks on DT platforms, as the IRQ base values
are dynamic in that case.
The patch set fixes this by specifying IRQs associated with GPIOs in IRQ
resources, populated automatically from the device tree. When IRQ resources
are specified the driver requires one IRQ resource per GPIO able to generate
an interrupt, and uses the translation table to compute the IRQ resource
offset instead of the IRQ number.
Patches 07/10 to 09/10 then add PFC interrupts in DT for the SH73A0, R8A73A4
and R9A7740 SoCs. The only missing platform here is SH7372 due to its very
uncomplete DT support. All other Renesas ARM platforms use a standaline GPIO
driver and are thus not affected.
Patch 10/10 finally adds a gpio-keys device to the Armadillo board DTS,
allowing the whole patch set to the tested.
The sh-pfc changes need to be merged first. Linus, could you please provide a
stable branch with the first 6 patches when you will apply them to your tree ?

This makes catching duplicate entries easier. Merge the two IRQ9 entries
found after sorting.

* [PATCH 06/10] sh-pfc: Support GPIO to IRQ mapping specified IRQ resources

On non-DT platforms IRQ controllers associated with the GPIOs have a
fixed IRQ base value known at compile time. The sh-pfc driver translates
GPIO number to IRQ numbers using a hardcoded table. This mechanism
breaks on DT platforms, as the IRQ base values are dynamic in that case.
Fix this by specifying IRQs associated with GPIOs in IRQ resources,
populated automatically from the device tree. When IRQ resources are
specified the driver requires one IRQ resource per GPIO able to generate
an interrupt, and uses the translation table to compute the IRQ resource
offset instead of the IRQ number.

fixed IRQ base value known at compile time. The sh-pfc driver translates
GPIO number to IRQ numbers using a hardcoded table. This mechanism
breaks on DT platforms, as the IRQ base values are dynamic in that case.
Fix this by specifying IRQs associated with GPIOs in IRQ resources,

offset instead of the IRQ number.

It seems to me that if Linus applies the pfc changes the
shmobile changes could be applied independently. Am I missing
and do the shmobile patches have build-dependencies on the pfc patches?

The DTS patches will result in the PFC platform device having IRQ resources.
The sh-pfc driver currently supports MEM resources only and will crash.

Another solution to the same problem: terminate with
USHRT_MAX and for (k = 0; gpios[k] != USHRT_MAX; k++) {}

I've applied the PFC changes to the pin control tree and will push
to kernelorg shortly, then allow it to stablilze before you attempt to
pull that into the SH mobile tree please, and notify me before
doing so and make sure to just pick the top commit you need.
