From: David Daney Date: Fri, 2 Jan 2009 13:50:00 +0000 (+0000) Subject: Serial: UART driver changes for Cavium OCTEON. X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6b06f19151c335ee0c5b61839fa4e6838182ebb8;p=linux-beck.git Serial: UART driver changes for Cavium OCTEON. Cavium UART implementation is not covered by existing uart_configS. Define a new uart_config (PORT_OCTEON) which is specified by OCTEON platform device registration code.
