Here's a series to add a real clock provider on Raspberry Pi.
Previously, we've been using a mix of fixed clocks from clk-bcm2835.c
(though some of them failed to get used by their intended consumers),
and fixed-clock nodes in the DT.
This driver gives us the ability to enable/disable our clocks,
the firmware driver isn't supported yet, but it
also avoids issues with disabling unused clocks due to them not yet
being connected to their consumers in the DT.

This one definitely needs a patch description, since someone might not
know what a VC4 is, and git log won't show the text from the binding

This interrupt controller is the new root interrupt controller with
the timer, PMU events, and IPIs, and the bcm2835's interrupt
controller is chained off of it to handle the peripherals.
I wrote the interrupt chip support, while Andrea Merello wrote the IPI
code.

This is a new per-cpu root interrupt controller on the Raspberry Pi 2,
which will chain to the bcm2835 interrupt controller for peripheral
interrupts.

Please read the FAQ at http://www.tux.org/lkml/
The BCM2836 (Raspberry Pi 2) uses two levels of interrupt handling
with the CPU-local interrupts being the root, so we need to register
ours as chained off of the CPU's local interrupt.

v3: Use
I'm also avoiding requests to set rate/state when they're a no-op, as
apparently no-op changes to pixel clock break the firmware-configured
display setup. It *shouldn't* change anything, but I've confirmed
that setting the CPU clock works fine, and after a couple of weeks of
prodding pixel clock

v2: Rename our compat string to mention bcm2835, and make our firmware
phandle be under a vendor-namespaced property.
v3: Squashed in the patches to reference the other clocks, to avoid
regressions now
The hardware clocks are not controllable by the ARM, so we have to
make requests to the firmware to do so from the VPU side. This will
let us replace fixed clocks in our DT with actual clock control (and
correct frequency information).

also avoids issues with disabling unused clocks due to them not yet
