Add a new address space/memory resource to d_can device tree node. D_CAN
RAM initialization is achieved through RAMINIT register which is part of
AM33XX control module address space. D_CAN RAM init or de-init should be
done by writing instance corresponding value to control module register.
Till we have a separate control module driver to write to control module,
d_can driver will handle the register writes to control module by itself.
So a new address space to represent this control module register is added
to d_can driver.

With device-tree framework ip instance number is "-1" by default for all

omap3_noncore_dpll_set_rate() attempts an enable of bypass clk as well
as ref clk for every .set_rate attempt on a noncore DPLL, regardless of
whether the .set_rate results in the DPLL being locked or put in bypass.
Early at boot, while some of these DPLLs are programmed and locked
(using .set_rate for the DPLL), this causes an ordering issue.
For instance, on OMAP5, the USB DPLL derives its bypass clk from ABE DPLL.
If a .set_rate of USB DPLL which programmes the M,N and locks it is called
before the one for ABE, the enable of USB bypass clk (derived from ABE DPLL)
then attempts to lock the ABE DPLL and fails as the M,N values for ABE
are yet to be programmed.
To get rid of this ordering needs, enable bypass clk for a DPLL as part
of its .set_rate only when its being put in bypass, and only enable the
ref clk when its locked.

WDT1 module can take one of the below clocks as input functional
clock -
- On-Chip 32K RC Osc [default/reset]
- 32K from PRCM
The On-Chip 32K RC Osc clock is not an accurate clock-source as per
the design/spec, so as a result, for example, timer which supposed
to get expired @60Sec, but will expire somewhere ~@40Sec, which is
not expected by any use-case.
The solution here is to switch the input clock-source to PRCM
generated 32K clock-source during boot-time itself.

Merge tag 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC bug fixes from Arnd Bergmann:
"Four patches for arm-soc this week:
- Kevin Hilman is no longer reachable under his previous email
address. He submitted the patch earlier, but nobody felt
responsible to pick it up.
- One Tegra fix for an incorect register address in device tree.
- IMX multiplatform support exposes a configuration option that leads
to unbootable kernels on all other machines and that needs to
depend on that platform.
- A nontrivial bug fix for the setup of the mxs video output."
