From fc4a9030788548414ccdd9d04aa457d4e027ecaa Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Tue, 2 Jul 2019 13:48:52 -0300 Subject: dmaengine: Revert "dmaengine: fsl-edma: support little endian for edma driver" This reverts commit 002905eca5bedab08bafd9e325bbbb41670c7712. Commit 002905eca5be ("dmaengine: fsl-edma: support little endian for edma driver") incorrectly assumed that there was not little endian support in the driver. This causes hangs on Vybrid, so revert it so that Vybrid systems could boot again.
