From ebd805cc14bec607e74795b7933570f240508cb4 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Fri, 27 Sep 2013 19:56:31 +0100 Subject: [PATCH] spi/s3c64xx: Factor transfer start out of enable/disable_cs() The hardware level /CS handling is tied to the start of the data path so is rolled into the same function as we use to manipulate GPIO /CS. In order to support factoring out the /CS handling into the core separate the two and explicitly start transfers separately to the /CS handling.
