From 4166a56aa8d5babe979d8e0834a741c9f015ad14 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Sat, 20 May 2017 23:42:50 +0200 Subject: ARM/dmaengine: pl08x: pass reasonable memcpy settings We cannot use bits from configuration registers as API between platforms and driver like this, abstract it out to two enums and mimic the stuff passed as device tree data. This is done to make it possible for the driver to generate the ccfg word on-the-fly so we can support more PL08x derivatives.
