Subject: [PATCH 33/86] hwmon: (k10temp) Support up to 12 CCDs on AMD Family of
processors
commit 8bb050cd5cf494f3d0cb45a6b54a476af09edb8d upstream
The current driver can read the temperatures from upto 8 CCDs
(Core-Complex Die).
The newer AMD Family 19h Models 10h-1Fh and A0h-AFh can support up to
12 CCDs. Update the driver to read up to 12 CCDs.
