From 70edba0784770a54e589058982ac2325d4284e99 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 8 Aug 2021 12:20:19 -0600 Subject: [PATCH] dma: Add a Kconfig for legacy DMA We cannot use the existing DMA config for the MCD driver because it is not migrated to driver model. In order to move it to drivers/Makefile we need some sort of option for it. Add a new DMA_LEGACY option, which also acts as a signal that it should be migrated. Enable this for devkit3250 which uses CONFIG_DMA_LPC32XX which is not converted to Kconfig. For now this is not used in the Makefile. That update happens in a following patch.
