On certain platforms like Amlogic Meson gpiod_to_irq() isn't supported
due to the design of gpio / interrupt controller. Therefore provide an
option for drivers to pass the card detect interrupt number
(retrieved e.g. from device tree) to mmc core.

v2:
- use another mechanism for passing and storing the cd interrupt
- add patch 2

Heiner Kallweit (3):
  mmc: core: support setting card detect interrupt from drivers
  dt-bindings: mmc: meson-gx: support specifying cd interrupt
  mmc: meson-gx: support platform interrupt as card detect interrupt

Applied for next, thanks!

A bit too fast. Binding is incorrect - suggests ABI break and makes
interrupts not described enough.

Best regards,
Krzysztof

Sorry! Thanks for pointing this out. Heiner is fixing this with an
incremental patch on top, please help to review.

Kind regards
