From 52ef8efcb75e8a8aab88e74c1376c2785d9a5452 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Sat, 2 Apr 2022 00:28:23 +0200 Subject: dma: omap: hide legacy interface The legacy interface for omap-dma is only used on OMAP1, and the same is true for the non-DT case. Make both of these conditional on CONFIG_ARCH_OMAP1 being set to simplify the dependency. The non-OMAP stub functions in include/linux/omap-dma.h are note needed any more either now, because they are only called on OMAP1.
