Subject: [PATCH 1/2] MIPS: Netlogic: Fix USB block's coherent DMA mask
Date: Wed, 17 Jul 2013 16:57:25 +0530 [thread overview]
Message-ID: <1374060446-25902-1-git-send-email-jchandra@broadcom.com> (raw)
From: Ganesan Ramalingam <ganesanr@broadcom.com>
The on-chip USB controller on Netlogic XLP does not suppport
DMA beyond 32-bit physical address. Set the coherent_dma_mask
of the USB in its PCI fixup to support this.
