From 37e466408796300ec935e15f01b4ca88678b96ef Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Wed, 6 Feb 2008 01:38:15 -0800 Subject: spi: SuperH SPI using SCI Add support for SPI over SCI pins. SCI is a very simple serial controller block that can be found on older SuperH processors. In theory it is possible to use the SCI hardware block in syncronous mode, but this version of the driver simply hooks up the bit banging code on the SCI pins.
