A call to of_iomap does not request the memory region.
This patch adds the function of_io_request_and_map which requests
the memory region before mapping it.

This patch adds a clock source and clock event for the timer found
on the Mediatek SoCs.
The Mediatek General Purpose Timer block provides five 32 bit timers and
one 64 bit timer.
Two 32 bit timers are used by this driver:
TIMER1: clock events supporting periodic and oneshot events
TIMER2: clock source configured as a free running counter
The General Purpose Timer block can be run with two clocks. A 13 MHz system
clock and the RTC clock running at 32 KHz. This implementation uses the system
clock with no clock source divider.
The interrupts are shared between the different timers and have to be read back
from a register. We just enable one interrupt for the clock event. The clock
event timer is used by all cores.

This adds a generic devicetree board file and a dtsi for boards
based on MT6589 SoCs from Mediatek.
Apart from the generic parts (gic, clocks) the only component
currently supported are the timers.

I will take this patchset through my tree but this patch touches an area
I am not handling.
Olof, Arnd, do you mind to ack this patch ?
Thanks !

wouldn't it be easier to just take patches 1,2,3,4 through your tree and let
patches 5,6,7 go through arm-soc?
There is no compile-time dependency between the two parts, so they will come
together nicely in linux-next and during the merge-window.

Traditionally we usually take the DT changes through arm-soc, but as
long as we share the branch we might be ok. We tend to stick them in
different branches in our tree though, so rockchip will be a little
mis-sorted this release. Not a big deal, and we can deal with it.
-----------
So I'd assume splitting the patchset this way might be a nice solution?
