From 2e3e2a5e4fef586ae9b1cfef42823c0aef1797f4 Mon Sep 17 00:00:00 2001 From: Michael Williamson Date: Tue, 8 Feb 2011 07:59:55 -0500 Subject: davinci: spi: move event queue parameter to platform data For DMA operation, the davinci spi driver needs an event queue number. Currently, this number is passed as a IORESOURCE_DMA. This is not correct, as the event queue is not a DMA channel. Pass the event queue via the platform data structure instead. On dm355 and dm365, move the eventq assignment for spi0 out of resources array and into platform data.
