6943ee14e5 simple-bus: enable support for of-platdata
Just do nothing in post_bind if of-platdata enabled,
for there is no dm_scan_fdt_dev().

e160f7d430 dm: core: Replace of_offset with accessor
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.

2e3f1ff63f dm: Convert users from dm_scan_fdt_node() to dm_scan_fdt_dev()
This new function is more convenient for callers, and handles pre-relocation
situations automatically.

9f56917ab8 dm: core: make simple-bus compatible to simple-mfd
Simple MFD devices can bind children without special bus configuration.
Like Linux, let's handle "simple-mfd" in the same way as "simple-bus".

f33017716e dm: Support address translation for simple-bus
The 'ranges' property can be used to specify a translation from the system
address to the bus address. Add support for this using the dev_get_addr()
function, which devices should use to find their address.
