[PATCH v2] dt-bindings: mmc: arm,pl18x: Document interrupt-names property

[Marek Vasut]

Document interrupt-names property with "cmd_irq" interrupt name.
This fixes dtbs_check warnings when building current Linux DTs:

"
arch/arm/boot/dts/stm32mp153c-dhcom-drc02.dtb: mmc@58007000: Unevaluated properties are not allowed ('interrupt-names' was unexpected)
"

I don't think that anything relies on the name here. Should
it just be removed from the dts files then? The name does
not follow the usual conventions with the "_irq" postfix.

This hardware come in variants with one or two IRQs.

Either two: "cmd_irq", "data_irq"

Or one combined IRQ (logic OR between those two!)
I don't know what that should be called, perhaps
"cmd_data_irq".

Since all DTS:es then have to be patched an alternative
is as Arnd says to just delete the names. We should however
at the very least patch the bindings description: for the IRQs
to make the above situation clear.

Yours,
Linus Walleij

Done, bindings updated and stm32/qcom DTs cleaned up.
