From 9198769363d4dc1d63d49ecb2e2b189aceb42d94 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Sat, 7 May 2005 13:20:19 -0700 Subject: [PATCH] USB: pxa2xx_udc updates This has several small updates to the px2xx UDC driver: * small fixes from Eugeny S. Mints - local_irq_save() around potential endpoint disable race - fix handling of enqueue to OUT endpoints (potential oops) * add shutdown() method to disable any D+ pullup * rename methods accessing raw signals, referencing the signals * describes itself as for "pxa25x", since pxa27x is different Signed-off-by: David Brownell Signed-off-by: Greg Kroah-Hartman --- drivers/usb/gadget/pxa2xx_udc.h | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) (limited to 'drivers/usb/gadget/pxa2xx_udc.h') diff --git a/drivers/usb/gadget/pxa2xx_udc.h b/drivers/usb/gadget/pxa2xx_udc.h index 1f3a7d999da7..d0bc396a85d5 100644 --- a/drivers/usb/gadget/pxa2xx_udc.h +++ b/drivers/usb/gadget/pxa2xx_udc.h @@ -177,23 +177,23 @@ struct pxa2xx_udc { static struct pxa2xx_udc *the_controller; -/* one GPIO should be used to detect host disconnect */ -static inline int is_usb_connected(void) +/* one GPIO should be used to detect VBUS from the host */ +static inline int is_vbus_present(void) { if (!the_controller->mach->udc_is_connected) return 1; return the_controller->mach->udc_is_connected(); } -/* one GPIO should force the host to see this device (or not) */ -static inline void make_usb_disappear(void) +/* one GPIO should control a D+ pullup, so host sees this device (or not) */ +static inline void pullup_off(void) { if (!the_controller->mach->udc_command) return; the_controller->mach->udc_command(PXA2XX_UDC_CMD_DISCONNECT); } -static inline void let_usb_appear(void) +static inline void pullup_on(void) { if (!the_controller->mach->udc_command) return; -- cgit v1.2.3
