This patch adds CPU deep Idle and Cluster deep Idle states BUT it defines
the idle state for each cpu (defined under cpu-idle-states parameter)
only for the quad version therefore it does NOT activate CPU Idle

e2a393c699 arm64: dts: marvell: use aliases for SPI busses on Armada 7K/8K
We are currently using the cell-index DT property to assign SPI bus
numbers. This property is specific to the spi-orion driver, and
requires each SPI controller to have a unique ID defined in the Device
Tree.

As we are about to merge armada-cp110-master.dtsi and
armada-cp110-slave.dtsi into a single file, those cell-index
properties that differ between the master CP110 and the slave CP110
are a difference that would have to be handled.

In order to avoid this, we switch to using the "aliases" DT node to
assign a unique number to each SPI controller. This is more generic,
and directly handled by the SPI core.

This commit adds the relevant details in the Armada 7K/8K Device Tree
to properly mux the UART used for the serial console. Since there is
basically only one possible muxing for the UART0 on the AP, the muxing
configuration is described in armada-ap806.dtsi, and selected from the
individual boards (other boards could be using a different UART).

The Armada AP806 has 20 pins, and therefore 20 GPIOs (from 0 to 19

GPIO ranges handled:
0: mvebu-gpio GPIOS [0 - 19] PINS [0 - 19]

After this patch:

63dac0f492 arm64: dts: marvell: add gpio support for Armada 7K/8K
Enable gpio support for CP and AP on the Marvell Armada 7K/8K SoCs.

The Armada 8K has two CP110 blocks, each having two GPIO controllers.
However, in each CP110 block, one of the GPIO controller cannot be
used: in the master CP110, only the second GPIO controller can be used,
while on the slave CP110, only the first GPIO controller can be used.

On the other side, the Armada 7K has only one CP110, but both its GPIO
controllers can be used.

For this reason, the GPIO controllers are marked as "disabled" in the
armada-cp110-master.dtsi and armada-cp110-slave.dtsi files, and only
enabled in the per-SoC dtsi files.

  arm64: dts: Fix broken architected timer interrupt trigger

This resolves a non-obvious conflict between a bugfix from
v4.8 and a cleanup for the exynos7 platform.

f2a89d3b2b arm64: dts: Fix broken architected timer interrupt trigger
The ARM architected timer specification mandates that the interrupt
associated with each timer is level triggered (which corresponds to
the "counter >= comparator" condition).

A number of DTs are being remarkably creative, declaring the interrupt
to be edge triggered. A quick look at the TRM for the corresponding ARM
CPUs clearly shows that this is wrong, and I've corrected those.
For non-ARM designs (and in the absence of a publicly available TRM),
I've made them active low as well, which can't be completely wrong
as the GIC cannot disinguish between level low and level high.

The respective maintainers are of course welcome to prove me wrong.

While I was at it, I took the liberty to fix a couple of related issue,
such as some spurious affinity bits on ThunderX, and their complete
absence on ls1043a (both of which seem to be related to copy-pasting
from other DTs).

7eec659478 arm64: dts: marvell: adjust to the latest mv-xor-v2 DT binding
As suggested by Rob Herring, we should:

 1/ Use a SoC-specific compatible string in addition to the more generic
    one.

 2/ The generic compatible string has been changed from
    "marvell,mv-xor-v2" to "marvell,xor-v2".

We simply reflect the changes made to the Device Tree bindings to the
relevant Marvell 7K/8K Device Tree files.

The I2C controller found in the Marvell Armada 7K/8K provides the
bridge/offloading features, so the Device Tree should use the
marvell,mv78230-i2c compatible string instead of marvell,mv64xxx-i2c.

Node names should not contain an instance number, the unit address
serves to distinguish nodes of the same name. So rename the XOR nodes
to just xor@<address>.

d2b78fb6f2 arm64: dts: marvell: update Armada AP806 clock description
Following the review from the DT maintainers, the DT binding for the
clocks has changed, and we now use a DFX server node exposing a
syscon, with the clock nodes being subnodes of the DFX server
node. This commit therefore updates the AP806 Device Tree file to use
this new DT binding.

ec7e5a569b arm64: dts: marvell: add Device Tree files for Armada 7K/8K
This commit adds the base Device Tree files for the Armada 7K and 8K
SoCs, as well as the Armada 8040 DB board.

The Armada 7020, 7040 (7K family) and 8020, 8040 (8K family) are
composed of:

 - An AP806 block that contains the CPU core and a few basic
   peripherals. The AP806 is available in dual core configurations
   (used in 7020 and 8020) and quad core configurations (used in 8020
   and 8040).

 - One or two CP110 blocks that contain all the high-speed interfaces
   (SATA, PCIe, Ethernet, etc.). The 7K family chips have one CP110,
   and the 8K family chips have two CP110, giving them twice the
   number of HW interfaces.

In order to represent this from a Device Tree point of view, this
commit creates the following hierarchy:

 * armada-ap806.dtsi - definitions common to dual/quad ap806
   * armada-ap806-dual.dtsi - description of the two CPUs
     * armada-7020.dtsi - description of the 7020 SoC
     * armada-8020.dtsi - description of the 8020 SoC
   * armada-ap806-quad.dtsi - description of the four CPUs
     * armada-7040.dtsi - description of the 7040 SoC
       * armada-7040-db.dts - description of the 7040 board
     * armada-8040.dtsi - description of the 8040 SoC

The CP110 blocks are not described yet, and will be part of future
patch series.
