| * | dm: core: Replace of_offset with accessorSimon Glass2017-02-08-27/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function.

| * | dtoc: Replace dot with underscore to avoid compiler errorsSimon Glass2017-02-08-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | If there is a '.' in a compatible string, then dtoc will produce a struct with a name containing a '.'. This won't work, so replace it with '_'. Also add a suitable test to the sandbox device tree to catch this. Signed-off-by: Simon Glass <sjg@chromium.org>

I am moving CONFIG_CMD_UNZIP to defconfig files except UniPhier SoC family. I am the maintainer of UniPhier platform, so I know "select CMD_UNZIP" is better for this platform.
