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.
