(sorry for the late mail, this was stuck in my outbox because of
one failed recipient address)

I've applied this one on top, following the output of the build bot.

Subject: [PATCH] ARM: bcm2835: clarify RASPBERRYPI_FIRMWARE dependency

The firmware driver can be a loadable module, but the power domain
can only be built-in, so we get a build error in an allmodconfig
kernel:

:(.text+0x17e59c): undefined reference to `rpi_firmware_property'
:(.text+0x17e51c): undefined reference to `rpi_firmware_get'
:(.text+0x17e244): undefined reference to `rpi_firmware_property'

This changes the dependency to only allow the power domain code
to be enabled when the firmware driver is built-in. Other users
of the firmware driver may still be loadable modules and not
everyone needs the power domains, so we don't change the firmware
code.
