Just as /chosen may contain devices /firmware may contain devices, scan
for devices under /firmware too.

dm: core: Scan "/firmware" node by default

2018-09-18T14:12:21+00:00

All Linux firmware drivers are put under "/firmware" node
and it has support to populate "/firmware" node by default.

u-boot and Linux can share same DTB. In this case, driver
probe for devices under "/firmware" will not be invoked
as "/firmware" does not have its own "compatible" property.

This patch scans "/firmware" node by default like "/clocks".

dm: core: Move "/clock" node scan into function

2018-09-18T14:12:21+00:00

Create separate function for scanning node by path and
move "/clock" node scan code into that function.

This will be usable if scanning of more node is required.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

dm: core: make fixed-clock dt scan live dt compatible

2018-04-01T14:15:11+00:00

dm_scan_fdt_node can't work when live dt is active,
we should use dm_scan_fdt_live instead.

libfdt: move headers to and

2018-03-05T15:16:28+00:00

Thomas reported U-Boot failed to build host tools if libfdt-devel
package is installed because tools include libfdt headers from
/usr/include/ instead of using internal ones.

This commit moves the header code:
  include/libfdt.h         -> include/linux/libfdt.h
  include/libfdt_env.h     -> include/linux/libfdt_env.h

and replaces include directives:
  #include       -> #include 
  #include   -> #include

dm: replace dm_dbg() with pr_debug()

2017-10-04T16:00:21+00:00

As we discussed before in ML, dm_dbg() causes undefined reference
error if #define DEBUG is added to users, but not drivers/core/util.c

We do not need this macro because we can use pr_debug() instead, and
it is pretty easy to enable it for the DM core by using ccflags-y.

dm: core: add clocks node scan

2017-09-12T03:43:58+00:00

Currently, all fixed-clock declared in "clocks" node in device tree
can be binded by clk_fixed_rate.c driver only if each of them have
the "simple-bus" compatible string.
This constraint has been invoked here [1].

This patch offers a solution to avoid adding "simple-bus" compatible
string to nodes that are not busses.

dm: core: Scan the live tree when setting up driver model

When starting up driver model with a live tree we need to scan the tree
