The firmware leaves the pins in GPIO mode. Until we have a proper pinmux
driver hooked on we just need to bitbang SPI. No big deal, this is just
used for the power button and performance is not important.

A copy & paste oversight from MMP2; camera interrupts are handled

They've been cargo-culted from Open Firmware and I don't know what
purpose they serve. Perhaps they are meant to provide the OFW runtime.
In that case it's still okay to drop them from here; OFW is welcome to add
it upon boot.

Hi,
chained to this message is a handful of patches related to MMP device
trees and bindings. Please take a look and consider queueing them for

Thank you

The property specifies a list of GPIO-capable pins. Don't limit it to a
single element as there's presumably more than one GPIO pin.

Hi,
please consider attaching the patches chained to this message.
The last two are straighforward Kconfig changes that allow building mmp_tdma
and mmp_pdma as modules so that distros that will choose to enable the drivers
will not add bloat to their kernels for other platforms.

There is no reason the Marvell MMP two-channel audio DMA driver would have
