Hi all,
This patch just adds an object property to initialize the reset value of
CNTFRQ.
We noticed that Linux would complain that CNTFRQ would have a mismatch
compared to an expected value, and this was because TF-A was assuming
that CNTFRQ was initialized to a different value out of reset.
Sinc
This can have a non-zero reset value, and cause the kernel to complain
about a CNTFRQ mismatch if TF-A (or firmware in general) does not
initialize it (because it expects the value to be non-zero out of
reset).
To fix this, we'll just add an object property that people can use to
initialize the CN
