From cc973aecf0b0541918c5ecabe6c90d1f709b5f89 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Sun, 9 Sep 2018 22:16:42 +0200 Subject: MIPS: lantiq: Do not enable IRQs in dma open When a DMA channel is opened the IRQ should not get activated automatically, this allows it to pull data out manually without the help of interrupts. This is needed for a workaround in the vrx200 Ethernet driver. Signed-off-by: Hauke Mehrtens Acked-by: Paul Burton Signed-off-by: David S.
