I have posted  GTDT support separately :https://lkml.org/lkml/2016/2/1/660

devicetree driver and GTDT driver both export sbsa gwdt info to
"platform resource".

this driver get hardware info from platform resource.

I must be missing something.  How does the driver probe?  It only has an 
entry for device tree:

+		.of_match_table = sbsa_gwdt_of_match,

Doesn't there need to be an ACPI match table to probe on an ACPI system?
