Subject: [PATCH 0/2] add ehci-s5p AHB burst function
Date: Wed, 29 Feb 2012 12:41:21 +0000	[thread overview]
Message-ID: <1330519283-4722-1-git-send-email-sangwook.lee@linaro.org> (raw)

Enable burst transfer from AHB for EHCI.
This fixes data transfer issue of USB Ethernet with EHCI.
Without this patch, ping works and network utilities such as scp hardly works.

It was tested on Origen board with the following configs.
root at linaro-alip:~# lsusb -t
/:  Bus 02.Port 1: Dev 1, Class=root_hub, Driver=exynos-ohci/3p, 12M
/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=s5p-ehci/3p, 480M
   |__ Port 1: Dev 2, If 0, Class=vend., Driver=MOSCHIP usb-ethernet driver, 480M
