Subject: [PATCH 7/8] ARM/DTS/S3C64XX: add OHCI support
To: linux-arm-kernel@xxxxxxxxxxxxxxxxxxx
Cc: linux-samsung-soc@xxxxxxxxxxxxxxx
With this entry there is no more need to enable the S3C64xx SoC specific OHCI
adaption (USB_OHCI_HCD_S3C2410). Just enable the generic platform device
support (USB_OHCI_HCD_PLATFORM=Y) and you are done.
