Sorry Alan,
The original patch was very simple, but I revisited it to fix other
issues and forgot to add the relevant comments.
Port size is changed to fix a problem - WM8505 actually had 6 uart's
defined in platform data but the vt8500_ports variable was only 4.
I have added devicetree port id support as well.
No regression risks as the entire platform is being converted to
devicetree and existing code dropped in this patchset.
Patchv4 3/9 to follow.
Regards
Tony Prisk
