| |
3.2-stable review patch. If anyone has any objections, please let me know.
------------------ From: Arnaud Patard <apatard@hupstream.com>
commit aaa10eb1d0034eccc096f583fe308f0921617598 upstream.
The rules used to make 8250_pci "ignore" the PCH uarts are lacking pci subids entries, preventing it to match and thus is breaking serial port support for theses systems.
This has been tested on a nanoETXexpress-TT, which has a specifici uart clock.
