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
