Upstream Device Tree renaming has been a source of headache. In board code fixups,
we largely avoid this by creating reproducible names, but in the barebox device
trees that extend upstream ones, we still have often problems. This is unlikely
to change because device tree YAML schemas are forcing a lot of nodes being
renamed from specific identifies to generic ones (e.g. s/aips/bus/),
while in barebox, due to lack of phandles, we have been hardcoding the
name. dtc's forgiving nature made us more than once end up with
a duplicate dummy node, while the one we meant to override remained
unchanged.

I went down the rabbit hole and changed most of our device trees, so we get
a compile error if the upstream path change instead of having an unbootable
system at runtime. This coupled with a `make dtbs` target, that I still need to
figure out how to cleanly implement, should eliminate this class of regressions.

There are still some lower priority issues that need to be addressed:

* rave-sp nodes may break if upstream changes names
* The /.*-ddrm?c.dtsi/ files have memory overrides that are meant to be "weak"
* The tegra boards duplicate much of the SoC device trees that are now upstream
* Some parition nodes still have a parent that is not a phandle

I deem their breakage lower priority though and they  can follow later.
The ones fixed here are either real regressions, ones that I find more
likely to regress in future or clean up that was noticed during work on the
device trees.

@Sascha, would be great if the first 4 commits could make it into master. They
fix issues in 18 device trees. The series has not been tested on actual hardware.
I just hacked the Makefile to build all device trees on every commit along the
way.

Cheers,

There is no /soc/aips@50000000 node upstream any longer as it was
renamed with the 8d158e1a4091 ("dts: update to v5.7-rc1") sync.

Adjust the barebox device tree accordingly. It's likely that this
resulted in barebox v2020.06.0 USB connectivity breakage for the
i.MX50's second USB PHY.

Fixes: 8d158e1a4091 ("dts: update to v5.7-rc1")

With the upstream migration to memory@BASE_ADDRESS naming scheme in the
device tree of some SoC families, we now have multiple overlapping memory
nodes in some of the barebox device trees. Rename the defunct overrides, so
they once again override the upstream nodes.

  To: barebox; +Cc: Ahmad Fatoum

The spec[1] says that top level memory nodes `shall have device_type =
"memory"'. Since 8226f7f9 ("of: base: parse all available memory nodes"),
we parse only nodes with device_type = "memory", so we should add the
device_type property where ever it's missing. When the nodes were first
added, this wasn't an issue because the skeleton.dtsi defined a memory
skeleton with correct device_type, but this was removed upstream and
imported into barebox along with 1dc748b3 ("dts: update to v5.1-rc1").

Upstream device trees with a memory node were adapted to have
device_type = "memory" in-line. This wasn't the case for nodes defined
only within barebox. Rectify this now and rename the nodes to feature a
unit name as well to be aligned with the upstream trend.

There is no /smb@4000000 node upstream any longer as it was
renamed with the 8d158e1a4091 ("dts: update to v5.7-rc1") sync.

Adjust the barebox device tree accordingly. It's likely that this
resulted in barebox v2020.06.0 state, environment and update breakage on
the vexpress boards.

The pinctrl device is also on the APB in the base device tree. The
barebox device tree wrongly creates a new one top-level under /.
Move it to the correct location, so the upstream node is extended.

Many device trees upstream have moved to memory@BASE_ADDRESS for the
memory node instead of a unit-name-less memory node. This has resulted
in breakage[1] in barebox, because some device trees feature an upstream
memory size that's not available in all variants and the barebox device
tree must override it, not create a second correct node next to the broken
one and risk of_add_memory allocating banks with bogus sizes.

To avoid this happening in future, to memory or to other nodes, extension
of nodes should happen via phandles throughout, because a phandle is assumed
to be more stable and if one is removed a compile error results instead
of creating a new node somewhere. For nodes lacking a phandle, we can
use the &{/path} syntax to declare an anonymous phandle that will fail
to compile when the upstream path changes. This is better than having
devices fail to boot at runtime.

The upstream device tree already features a memory node with the correct
size, but with the name memory@80000000. Drop the differently-named
barebox node.

The container node of the leds has never had the name gpio_leds,
so there is no regression here, it just never worked.
Instead of fixing it, just drop it.

Prior to 8226f7f90973 ("of: base: parse all available memory nodes"),
barebox first looked at a /memory node, then at a node with a
device_type = "memory" property when probing available memory banks from
device tree. Linux instead only considered nodes with device_type =
"memory". The imx6ul-pico-hobbit predates the change in barebox behavior,
so it's unclear what is gained from dropping device_type = "memory" as
barebox used to parse the node by name anyway and Linux only saw the new
fixed up node.

Since then the Linux device tree has been split into a SoM and carrier
board device tree and the node name is now called memory@80000000 with
a size of 0 in the reg property. Because it's already used for boards
with differing memory size, we assume this will remain so and thus we
just drop the defunct barebox memory node override.

This was likely overlooked because they were separate commits.
Combine them now. No functional change.

A status = "disabled" node should act the same as if it were
uncommented, with the difference that a board that does have the
resistor populated could easily fixup the status.

The phandles are unreferenced anywhere. They are likely a remnant of
copy and paste from another device tree that makes use of them, e.g. the
socfpga_cyclone5_socrates.dts. Drop them.

Sync with the upstream device tree repository has been a common cause
for breakage in barebox. Often unnoticed:

* New bindings are merged upstream and device trees migrated, but
  barebox didn't yet have support
* Nodes are renamed upstream, but barebox still extends the old name,
  with duplicate nodes resulting

We can solve the second one by requiring dtc to give us errors when
paths we extend no longer exist. Document how to do so.

 then extends it with barebox-specifics like :ref:`barebox,state`,
 environment or boot-time device configuration.
 
+Device Tree probing largely happens via compatible properties with no special
+meaning to the node names themselves. It's thus paramount that any device tree
+nodes extended in the barebox device tree are referenced by a phandle, not by
+path, to avoid run-time breakage like this::
+
+  # Upstream dts/src/$ARCH/board.dts
+  / {
+  	leds {
+            led-red { /* formerly named red when the barebox DTS was written */
+            	/* ... */
+            };
+        };
+  };
+
+  # barebox arch/$ARCH/dts/board.dts
+  #include <$ARCH/board.dts>
+  / {
+  	leds {
+            red {
+                barebox,default-trigger = "heartbeat";
+            };
+        };
+  };
+
+In the prvious example, a device tree sync with upstream resulted in a regression
+as the former override became a new node with a single property without effect.
+
+Using phandles avoids this. When no phandle mapping the full path is defined
+upstream, the ``&{/path}`` syntax should be used instead, e.g.::
+
+  &{/leds/red} {
+      barebox,default-trigger = "heartbeat";
+  };
+
+This would lead to a compile error should the ``/leds/red`` path be renamed or
+removed. This also applies to uses of ``/delete-node/``.
+
+Only exception to this rule are well-known node names that are specified by
+the spec to be parsed by name. These are: ``chosen``, ``aliases`` and ``cpus``,
+but **not** ``memory``.

The am335x devices register their memory banks with values read back
from the memory controller in arch/arm/mach-omap/am33xx_scrm.c

The i.MX devices register their memory banks with values read back from
the memory controller in arch/arm/mach-imx/esdctl.c

For these boards it's probably better to remove the memory nodes
entirely.
