[PATCH v1 0/6] gpio: mlxbf2: Introduce proper interrupt handling

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

This is just a WIP / TODO series based on the discussion [1].
I hope nVidia will finish it and fix the initial problem sooner than later.

Bart, Linus, First 4 patches may be directly applied to the tree (they are
at least compile-tested, but I believe they won't change any functionality.

Patch 5 is some stubs that should have been done in the driver.
Patch 6 is follow up removal of custom GPIO IRQ handling from
Mellanox GBE driver. Both of them are quite far from finishing,
but it's a start for nVidia to develop and test proper solution.

In any case, I will probably sent end this week the ACPI IRQ abuse
part from the GBE driver (I won't touch OF path).

ARs for nVidia:
0) review this series;
1) properly develop GPIO driver;
2) replace custom code with correct one;
3) send the work for review to GPIO and ACPI maintainers (basically list
   of this series).

On my side I will help you if you have any questions regarding to GPIO
and ACPI.

Andy Shevchenko (6):
  gpio: mlxbf2: Convert to device PM ops
  gpio: mlxbf2: Drop wrong use of ACPI_PTR()
  gpio: mlxbf2: Use devm_platform_ioremap_resource()
  gpio: mlxbf2: Use DEFINE_RES_MEM_NAMED() helper macro
  TODO: gpio: mlxbf2: Introduce IRQ support
  TODO: net: mellanox: mlxbf_gige: Replace non-standard interrupt
    handling
