Subject: [PATCH v3 5/7] UDC: Use struct dma_pool instead of pci_pool
Date: Tue, 28 Mar 2017 16:32:07 +0530 [thread overview]
Message-ID: <1490698929-10915-6-git-send-email-raviteja.garimella@broadcom.com> (raw)
In-Reply-To: <1490698929-10915-1-git-send-email-raviteja.garimella@broadcom.com>
Using dma_pool instead of pci_pool will make snps_udc_core driver
to be compatible with non-pci platforms.
