[ARM] 3958/1: add platform device (pxa2xx-udc)to ixp4xx Create include/asm-arm/arch-ixp4xx/udc.h and add platfrom device ixp4xx_udc_device into arch/arm/mach-ixp4xx/common.c. This allows us to use pxa2xx-udc on the ixp4xx platfrom. Both pxa2xx and ixp4xx use the same device controller.

[ARM] 4141/1: consolidate functions that handles gpio in pxa2xx_udc This patch renames pxa_gpio_set/get functions defined in drivers/usb/gadget/pxa2xx_udc.h to udc_gpio_set/get. These functions are moved from drivers/usb/gadget/pxa2xx_udc.h to include/asm-arm/arch-pxa2xx/udc.h Creates new functions: udc_gpio_to_irq, udc_gpio_init_vbus, udc_gpio_init_pullup in include/asm-arm/arch-pxa2xx/udc.h. These functions are used in drivers/usb/gadget/pxa2xx_udc.c instead of direct low-level (pxa2xx only) functions. Creates all these udc_gpio_* functions in include/asm-arm/arch-ixp4xx/udc.h. This implementation has no real code because ixp4xx doesn't use vbus - only vbus uses all these gpio functions (and because ixp4xx misses any function which converts number of gpio pin into it's irq). This is next step to make pxa2xx_udc fully work on ixp4xx platform. Signed-off-by: Milan Svoboda <msvoboda@ra.rockwell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
