part of- This device node has no binding. The "host-wake" interrupt is
bindingI think the general mmc and interrupts bindings apply. And the mmcBroadcom SDIO Wi-Fi binding, rather than a generic one.
clearly states that for sub-nodes a compatible string is optional.part
However I just realized that the 'interrupt-names' property is not
of the general interrupts binding, so I guess at least this propertyshould
be removed.
Indeed. If the device just used the SDIO interrupt this is not needed.
The Broadcom device can use either SDIO interrupt or a so-called
out-of-band host-wake interrupt, which is what the above represents.
RTL8....S is also capable of use OOB interrupt.
