Changes since v2:
Updated binding patch commit description to specify that version is detected
using a register in IP.
Changes since v1:
Updated IP name and binding to axi-1wire-host and filenames to match. Comment
pruning where operation obvious, additional comments where not. Unwrapped
helper functions for register read/writes. Removed un-necessary device reset
on fail to add device. Fixed duplicate clock disable in remove function. Move
bus master structure to per instance. Improved hardware testing with multiple
w1 instances.
Add a host driver to support the AMD 1-Wire programmable logic IP block.
This block guarantees protocol timing for driving off-board devices such as
thermal sensors, proms, etc.
