From 6998b6c7c77e22d386fb8792365e668351d22f91 Mon Sep 17 00:00:00 2001 From: Vijay Kumar B Date: Wed, 28 Sep 2016 16:39:18 +0530 Subject: [PATCH] usb: Fix incorrect default DMA offset. The default DMA offset is set to 3. When the property is not set by the consumer, the default causes DMA access to be shifted by 3 bytes. In PXA, this results in incorrect DMA access, leading to error notification in the USB controller driver. A better default would be 0, so that there is no offset, when the consumer does not specify one. Signed-off-by: Vijay Kumar B. Reviewed-by: Deepak S.
