Stefan Agner 1c4e2a11ba ARM: dts: imx7d: add clock-frequency to CPU nodes
Add clock-frequency property to CPU nodes. Avoids warnings like
"/cpus/cpu@0 missing clock-frequency property".

Stefan Agner f5bd51b60f ARM: dts: imx7d: move CPU operating points to imx7d.dtsi
Only i.MX 7Dual SoC supports CPU frequencies of up to 1GHz. The i.MX
7Solo can run with up to 800MHz and does so without making use of DVFS
usually. While the device tree clearly specified a too fast operating
point for i.MX 7Solo, the kernel did not used it in practise so far
because the CPUfreq driver does not get loaded on i.MX 7Solo devices
(since the fsl,imx7s compatible string is not in the list of devices
making use of the cpufreq-dt driver...).

Stefan Agner 974a3abcff ARM: dts: imx7d: move ARM platform peripherals inside soc node
Since we have a SoC level node we should make use of it and have
all nodes which are within the SoC, inside that node. This also
saves an extra interrupt-parent properties. While at it, also
order the Coresight nodes according to register addresses.

Stefan Agner a67970a226 ARM: dts: imx7d: recreate imx7d.dtsi with i.MX 7Dual specifics
The i.MX 7Solo implements a subset of features available on
i.MX 7Dual. Recreate imx7s.dtsi as the base device tree for
i.MX 7Dual boards. The i.MX 7Dual's additional features over
i.MX 7Solo are:
- Second Cortex-A7 core
- Second Gigabit Ethernet controller
- EPD (Electronc Paper Display, not yet part of the device tree)
- PCIe (not yet part of the device tree)
- Additional USB2.0 OTG controller

Stefan Agner 3ef79ca6bd ARM: dts: imx7d: use imx7s.dtsi as base device tree
The i.MX 7 series currently consists of two SoCs: i.MX 7Solo and
7Dual. The former has a subset of features of the latter, hence
use imx7s.dtsi as the new base device tree. To keep diffstat nice,
just move imx7d.dtsi to imx7s.dtsi temporarily and recreate
imx7d.dtsi in a second commit.

Building with W=1 option leads to several warnings like:

Warning (unit_address_vs_reg): Node /soc/aips-bus@02000000/anatop@020c8000/regulator-1p1@110 has a unit name, but no reg property

Fix them by removing the unneeded unit-addresses.

Since uboot v2016.01-rc2, which supported basic psci for i.mx7d.
So imx7d's second core can be enabled by psci.

Without arch timer, every timer event will be boardcasted to each core.
arch timer has local timer irq for each core.

Linus Torvalds c0d6fe2f01 ARM: DT updates for v4.4
As usual, this is the massive branch we have for each release. Lots of
 various updates and additions of hardware descriptions on existing hardware,
 as well as the usual additions of new boards and SoCs.
 
 This is also the first release where we've started mixing 64- and 32-bit
 DT updates in one branch.
 
 (Specific details on what's actually here and new is pretty easy to tell
 from the diffstat, so there's little point in duplicating listing it here.)
