From ad6c1d43964dcba57bfe20b7185af5a71f94a1b7 Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Tue, 24 Apr 2012 18:06:53 -0700 Subject: ARM: S3C24XX: claim spi channels for hsspi in dma-s3c2443 SoCs starting with the S3C2443 contain SPI controllers compatible with the spi-s3c64xx driver and therefore need separate dma channels for rx and tx. This patch introduces dma channel declarations for these and changes the dma-s3c2443.c accordingly. None of the older SoCs use the spi-dma at all. Most boards bitbang their spi use and the spi-s3c24xx driver also does not use the dma system.
