2017-02-08dm: core: Replace of_offset with accessorSimon Glass
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.

2016-11-21gpio: dwapb: Add support for port BPhil Edworthy
The IP supports two ports, A and B, each providing up to 32 gpios. The driver already creates a 2nd gpio bank by reading the 2nd node from DT, so this is quite a simple change to support the 2nd bank.

2016-10-13libfdt: Bring in upstream stringlist functionsSimon Glass
These have now landed upstream. The naming is different and in one case the function signature has changed. Update the code to match. This applies the following upstream commits by Thierry Reding <treding@nvidia.com> : 604e61e fdt: Add functions to retrieve strings 8702bd1 fdt: Add a function to get the index of a string 2218387 fdt: Add a function to count strings Signed-off-by: Simon Glass <sjg@chromium.org>
