From db72da92103e3023e6a4fdfe65183b21bfe5d883 Mon Sep 17 00:00:00 2001 From: Lee Jones Date: Fri, 3 May 2013 15:32:03 +0100 Subject: dmaengine: ste_dma40: Calculate number of logical channels from physical ones This change will cost ~25KB of memory, but it's worth the trade-off, as it removes a great deal of overhead. It means that instead of only allocating memory for the logical channels in use, it does so for all available ones, which is 32 per physical channel. However, this now means we can remove some platform data and we don't have to worry about adding vendor specific variables to Device Tree.
