If anyone has any objections, please let me know. ------------------ From: Bryan O'Donoghue [ Upstream commit b4053a2097ec2f8ea622e817ae5a46a83b23aefe ] New silicon means that the pre-determined offsets we have been using in this driver no longer hold. Existing blocks of registers can exist at different offsets relative to the IO base address. This commit adds a routine to assign the IO base hooks a subsequent commit will convert from absolute to relative addressing.
