From 64c535e942af6cfe59ceceeb9bc6ba5f437a2fc9 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Fri, 6 Dec 2013 10:59:49 +0100 Subject: sh: sh772[34]: Set serial port sampling rate to 8 for SCIFA ports SCIFA ports on sh7723 and sh7724 seem to use a sampling rate of half the value specified in the datasheet. This is currently handled by a custom baud rate calculation algorithm. The algorithm ID will be removed from platform data, set the sampling rate directly instead.
