* [PATCH v9 3/3] ARM: shmobile: BOCK-W: add USB support @ 2013-06-08 20:18 ` Sergei Shtylyov 0 siblings, 0 replies; 10+ messages in thread From: Sergei Shtylyov @ 2013-06-08 20:18 UTC (permalink / raw) To: linux-arm-kernel Register the USB PHY device from bockw_init(), passing the platform data to it. Set machine's init_late() method to r8a7778_init_late() in order for [EO]HCI to get registered too... Don't forget to add USB PENC0/1 pins to bockw_pinctrl_map[]. The patch has been tested on the BOCK-W board. Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com> --- Changes since version 8: - resolved reject, refreshed the patch. Changes since version 6: - added USB PENC0/1 pins to bockw_pinctrl_map[]. Changes since version 4: - annotated 'usb_phy_platform_data' as '__initdata' since it's kmemdup()'ed while registering the platform device anyway; - refreshed the patch.
