[PATCH 0/4] dm: core: Support same compatible in host/gadget musb drivers

Hi,

musb currently uses a wrapper driver that binds on the parent device of
the actual musb devices to manage the differentiation between gadget and
host modes. However in the upstream devicetree this parent devicetree
node can not be used to match the wrapper driver.

To be able to probe the musb devices in host/gadget mode directly, this
series introduces support for returning -ENODEV in bind functions
resulting in iterating the remaining drivers potentially binding to
other drivers that match the compatible.

It also changes the address parsing of musb-ctrl to be able to parse
relative addresses.

Best
Markus
