drm/vc4: Reading the hotplug register is only valid if no GPIO defined
The order of precedence should be:
- hotplug GPIO being defined
- DDC probe
- hotplug register
In particular the hotplug register is not valid if a GPIO is defined
(eg on Pi0-3), but was being checked.

gpio: Add gpio-fsm driver
The gpio-fsm driver implements simple state machines that allow GPIOs
to be controlled in response to inputs from other GPIOs - real and
soft/virtual - and time delays. It can:
+ create dummy GPIOs for drivers that demand them,
+ drive multiple GPIOs from a single input, with optional delays,
+ add a debounce circuit to an input,
+ drive pattern sequences onto LEDs
etc.

net: bcmgenet: Reset RBUF on first open
If the RBUF logic is not reset when the kernel starts then there
may be some data left over from any network boot loader. If the

Extend bcmgenet_dma_disable to do perform the reset, but not when
called from bcmgenet_resume in order to preserve a wake packet.
N.B. This different handling of resume is just based on a hunch -
why else wouldn't one reset the RBUF as well as the TBUF? If this
isn't the case then it's easy to change the patch to make the RBUF
reset unconditional.
