The VPU clock is also the clock for our AXI bus, so we really can't
disable it. This might have happened during boot if, for example,
uart1 (aux_uart clock) probed and was then disabled before the other

I like that this flag is going away. It's a nice cleanup.

These are for fixing the vc4 driver on the Pi 3. Note that patch 2
will also be necessary for fixing HPD on the Pi2, which we've been
carrying downstream patches to work around until now.

drm/vc4: Let gpiolib know that we're OK with sleeping for HPD.

The original Raspberry Pi had the GPIO active high, but the later
models are active low. The DT GPIO bindings allow specifying the
active flag, except that it doesn't get propagated to the gpiodesc, so
you have to handle it yourself.

Fixes an error thrown every few seconds when we poll HPD when it's on
a I2C to GPIO expander.

The DT bindings for pinctrl-bcm2835 allow both the function and pull
to contain either one entry or one per pin. However, an error in the
DT parsing can cause failures if the number of pulls differs from the
number of functions.

This improves read speed on my SD card (as reported by hdparm -t) from
10.15MB/sec to 16.70MB/sec. Once we add slave DMA, we can get to
18.45MB/sec.

it and it sounds useful to bring over.
