From b2c6561605da4802886cafe96432b8e2968e9edc Mon Sep 17 00:00:00 2001 From: Andrew Victor Date: Thu, 8 Feb 2007 09:42:40 +0100 Subject: [ARM] 4145/2: AT91: Add support for AT91SAM9263 processor Add support for the Atmel AT91SAM9263 processor. It is similar to the AT91SAM9260 but with more integrated peripherals, 5 GPIO banks, etc. Original patch from Nicolas Ferre.

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.
