The start of an ACPI path typically has backslashes in it. These are not
preserved during the translation from device tree to C code, since dtc
(correctly) uses the first backslash as an escape character, and dtoc
therefore leaves it out of the C string.
Fix this with special-case handling.

In the current implementation, when dtoc parses a dtb to generate a struct
platdata it converts the information related to linked nodes as pointers
to struct platdata of destination nodes. By doing this, it makes
difficult to get pointer to udevices created based on these
information.
This patch extends dtoc to use struct driver_info when populating
information about linked nodes, which makes it easier to later get
the devices created. In this context, reimplement functions like
clk_get_by_index_platdata() which made use of the previous approach.

As dtoc now performs checks for valid driver names, when running dtoc

Currently dtoc scans dtbs to convert them to struct platdata and
to generate U_BOOT_DEVICE entries. These entries need to be filled
with the driver name, but at this moment the information used is the
compatible name present in the dtb. This causes that only nodes with
a compatible name that matches a driver name generate a working
entry.
In order to improve this behaviour, this patch adds to dtoc the
capability of scan drivers source code to generate a list of valid driver
names and aliases. This allows to generate U_BOOT_DEVICE entries using
valid driver names and rise a warning in the case a name is not valid.

Since the state module holds references to all the device trees used by
binman, it must be updated when the device trees are updated. Add support
for this.
Signed-off-by: Simon Glass <sjg@chromium.org>
At present EnsureCompiled() uses an file from the 'output' directory (in
the tools module) when compiling the device tree. This is fine in most
cases, allowing useful inspection of the output files from binman.
However in functional tests, _SetupDtb() creates an output directory and
immediately removes it afterwards. This serves no benefit and just
confuses things, since the 'official' output directory is supposed to be
created and destroyed in control.Binman().
Add a new parameter for the optional temporary directory to use, and use a
separate temporary directory in _SetupDtb().

There are quite a few changes since we decided to split the

The Fdt.del_node() method was unfortunately missed in this process and
will be dealt with later. It exists in U-Boot but not upstream.
Further syncing of libfdt probably needs to wait until we assess the
code-size impact of all the new checking code on SPL and possibly provide
a way to disable it.
