From a9ce1afb35317d2a0646c7530f0ae9822c93cd69 Mon Sep 17 00:00:00 2001
From: Gregory CLEMENT <gregory.clement@free-electrons.com>

Subject: ARM: mvebu: Fix the Aurora L2 cache node with the required
cache-unified property
The L2 cache controller on the Armada 370 and Armada XP SoCs is a
unified cache. Moreover, the Aurora cache controller is compatible
with the L2x0 cache controller: the "cache-unified" property is
required by its binding.
This patch fixes the Aurora L2 cache node for the Armada 370 and
Armada XP SoCs by adding this property.

Subject: ARM: mvebu: armada-xp: Consolidate pinctrl node
All current Armada XP SoCs have their pin controller at 0x18000/0x38.
Move the common properties of pinctrl nodes to armada-xp.dtsi to allow
to share pinctrl settings later.

Subject: ARM: mvebu: armada-xp: Add node alias to pinctrl and add base address
In other MVEBU SoCs, the pin controller node is called pin-ctrl with
its base address added. Also, we have a node alias to access the pinctrl
node easily. Fix this for Armada XP pinctrl nodes to be consistent with
other SoCs.

Subject: ARM: mvebu: armada-xp: Move GE0/1 pinctrl settings for RGMII
Pinctrl settings for GE0 and GE1 are not only usable on RD-AXPWiFiAP.
Moreover, naming the RGMII settings pmx-ge{0,1} is not precise enough
as there is also a GMII setting for GE0.
Move the pinctrl sub-nodes to the common pinctrl node and rename them
to pmx-ge{0,1}-rgmii.

Subject: arm: mvebu: add uartX labels for Armada SoC serial nodes
This patch adds uartX labels for Armada SoC serial nodes. This is
a preliminary work to be able to easily reference the serial lines
in Device Tree files. One expected use is when providing stdout-path
property for barebox.

From 4904a82a9399d037588162e6fb4b293fa6a37f7c Mon Sep 17 00:00:00 2001

Subject: arm: mvebu: move Armada 370/XP pinctrl node definition
armada-370-xp.dtsi
What was done by Sebastian in 264a05e19bf5 ("ARM: mvebu: armada-xp:
Add node alias to pinctrl and add base address") and 01c434225ee6
("ARM: mvebu: armada-xp: Use pinctrl node alias") can also be done for
Armada 370, i.e.
- Rename Armada 370 pinctrl node to pin-ctrl with its address encoded
- Add a node alias to access the pinctrl node easily.
- use the newly available alias in existing Armada 370 .dts files
We can even go a bit further by putting the pinctrl node definition in
armada-370-xp.dtsi, with only its reg property defined. This allows us
to then also use the newly defined node alias in armada-xp.dtsi,
armada-370.dtsi.

Subject: arm: mvebu: define and use common Armada XP SPI pinctrl setting
This patch defines common Armada XP pinctrl settings in armada-xp.dtsi
for the supported SPI interface (MPP36-39) and use it as default
for Armada XP spi interface. That being done, it removes the now
redundant definitions in armada-xp-axpwifiap.dts.
Note: this patch has the potential to break out-of-tree users w/o
specific pinctrl settings for their spi interfaces if the default
above does not match their config (i.e. if they do not use CS0).

From 70ee4e9d9f054e258480fd51c90cfc2b72be8b78 Mon Sep 17 00:00:00 2001
From: Arnaud Ebalard <arno@natisbad.org>

Subject: arm: mvebu: normalize pinctrl entries for Armada SoCs
There are currently 2 differents naming conventions used between the
existing Armada SoC DT files for pinctrl entries (*_pin(s): *-pin(s)
and pmx_*: pmx-*) with a vast majority of files using the former:
$ grep _pin arch/arm/boot/dts/armada-*.dts* | wc -l
155
$ grep pmx arch/arm/boot/dts/armada-*.dts* | wc -l
13
In fact, only some Armada XP files are using the second variant.
This patch normalizes those files (mainly ge0/1 entries) to use
the first variant.

This commit adds the implementation of ->suspend() and ->resume()
platform_driver hooks in order to save and restore the state of the
GPIO configuration. In order to achieve that, additional fields are
added to the mvebu_gpio_chip structure.
