From d1e7780638a9192f15caf590e0081bf915fdef71 Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Tue, 15 Apr 2008 14:34:46 -0700 Subject: spi: spi_s3c24xx must initialize num_chipselect The SPI core now expects num_chipselect to be set correctly as due to added checks on the chip being selected before an transfer is allowed. This patch adds a num_cs field to the platform data which needs to be set correctly before adding the SPI platform device.
