This patch set contains four small patches that bring devicetree functionality to w1 bus masters and slaves in general. As an example, the DS2760 driver is made aware of devicetree nodes as an example. Other drivers can easily be ported later. W1 masters scan their bus in order to discover slave devices. Once one is found, a driver matching the family of the device is instanciated which handles it. All that's needed for now is a call to of_find_matching_node() when a slave device is attached, so the corresponding of_node pointer is set. The series also contains a patch that merges the w1 slave driver for the DS2760 battery monitor into its only user, the ds2760 supply driver. The indirection with two drivers never had any benefit, and here is a good opportunity to clean this up. Patch #1 adds some DT bindings documentation Patch #2 adds the call to of_find_matching_node() Patch #3 merges the w1 slave and the supply driver for ds2760 Patch #4 makes the ds2760 supply driver aware of DT environments This works fine on a PXA3xx based board with a battery attached to the w1-gpio bus master controller.
