2007-02-07USB: at91_udc wakeup event updatesDavid Brownell
This updates the AT91 UDC driver's handling of wakeup events: - Fix a bug in the original scheme, which was never updated after the {enable,disable}_irq_wake() semantics were updated to address refcounting issues (i.e. behave for shared irqs). - Couple handling of both type of wakeup events, to be more direct. The controller can be source of wakeup events for cases like bus reset and USB resume. On some boards, VBUS sensing is also IRQ driven.

2006-12-20USB: at91_udc, misc fixesAndrew Victor
This is an update to the AT91 USB Device (Gadget) driver. Adds support for the Atmel AT91SAM9260 and AT91SAM9261 processors. The only difference is how they handle the pullup pin. [Patch from Patrice Vilchez] Need to clear any pending USB Device interrupts before registering the interrupt handler. The bootloader might have been using the USB Device port. [Patch from Peer Georgi] VBUS detection is handled by a GPIO interrupt which only triggers on a change. Is is therefore necessary to read the current VBUS state explicitly at startup.

2006-12-20USB: at91 udc, support at91sam926x addressesAndrew Victor
This is an update to the AT91 USB Device (Gadget) driver. The base I/O address provided in the platform_device resources is now ioremap()'ed instead of using a statically mapped memory area. This helps portability to the newer AT91sam926x processors. The major change is that we now have to pass a 'struct at91_udc' parameter to at91_udp_read() and at91_udp_write().

2006-08-02USB: AT91 UDC updates, mostly power managementDavid Brownell
UDC updates for AT91 series processors: - Get ready for at91sam926x processors (ARMv5tej not ARMv4t) - Suspend/resume support now behaves properly - In "standby" mode, UDC can be a source of system wakeup events (host resume, device connect/disconnect, etc) - Fix IRQ storming issues, seemingly related to clock disabling changes that went in a while back And minor cleanups, especially whitespace.

2006-03-20[PATCH] USB: add support for AT91 gadgetDavid Brownell
This adds support for the USB peripheral controller on AT91 (rm9200, eventually also sam9261 or uClinux) platforms. More SOC support for Linux-USB ... an uncomplicated pure PIO driver. It'd be worth using this as a model, if you're starting a driver for some other peripheral controller.
