* MUSB driver: Timeout is never detected as the while loop does not endMatej Frančeškin2012-09-01-1/+1
| | | | | | | | | | | | | | | | | Timeout variable is decremented once more when while condition is not met. Following "if" does not detect correctly that timeout has occurred. Because of this bug the "usb start" command on AM335X-EVM board did not detect correctly that USB device was not attached. timeout = musb_cfg.timeout; while (timeout--) if (readb(&musbr->devctl) & MUSB_DEVCTL_HM) break; /* if musb core is not in host mode, then return */ if (!timeout) return -1; Signed-off-by: Matej Franceskin <Matej.Franceskin@comtrade.com> CC: Marek Vasut <matex@denx.de>?

* USB: move keyboard polling into kbd driveramartin@nvidia.com2012-03-03-28/+0
| | | | | | | | | This moves keyboard polling logic from USB HCD drivers into USB keyboard driver. Remove usb_event_poll() as keyboard polling was the only user of this API. With this patch USB keyboard works with EHCI controllers again. Tested on a tegra2 seaboard. Signed-off-by: Allen Martin <amartin@nvidia.com>

* musb: process control messages after roothub accepted itCliff Cai2011-06-25-2/+5
| | | | | | | | | | When dealing with non-multipoint devices, if the software root hub code accepted the message, then we still need to process it normally. So only return quickly when the root hub skipped the message or is otherwise in an error state. Signed-off-by: Cliff Cai <cliff.cai@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* usb: musb: only write CLRDATATOG when appropriateBryan Wu2010-10-13-7/+16
| | | | | | | | | | This is a change similar to what is already in the Linux driver. We should only program the CLRDATATOG bit when the current mode indicates that it is needed.

* usb: musb: setup TXCOUNT for Blackfin musbBryan Wu2010-09-11-0/+5

* usb: musb: add virtual root hub control supportBryan Wu2010-01-12-2/+427
| | | | | | | | | For MUSB devices that do not support multipoint (hubs), we have to emulate a root hub so that we can support core operations like resetting ports.

* usb: musb: change rxcsr register from write to read/modify/writeBryan Wu2010-01-09-2/+4
| | | | | | | | | | | | | The RX Control/Status register has bits that we want to preserve, so don't just write out a single bit. Preserve the others bits in the process. The original code posted to the u-boot list had this behavior, but looks like it was lost somewhere along the way to merging.

* usb: musb: make multipoint optionalBryan Wu2010-01-09-0/+20
| | | | | | | | | | The multipoint handling under MUSB is optional, and some parts (like the Blackfin processor) do not implement support for it.

* USB Consolidate descriptor definitionsTom Rix2009-12-20-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The header files usb.h and usbdescriptors.h have the same nameed structure definitions for usb_config_descriptor usb_interface_descriptor usb_endpoint_descriptor usb_device_descriptor usb_string_descriptor These are out right duplicates in usb.h usb_device_descriptor usb_string_descriptor This one has extra unused elements usb_endpoint_descriptor unsigned char bRefresh unsigned char bSynchAddress; These in usb.h have extra elements at the end of the usb 2.0 specified descriptor and are used. usb_config_descriptor usb_interface_descriptor The change is to consolidate the definition of the descriptors to usbdescriptors.h. The dublicates in usb.h are removed. The extra element structure will have their name shorted by removing the '_descriptor' suffix. So usb_config_descriptor -> usb_config usb_interface_descriptor -> usb_interface For these, the common descriptor elements are accessed now by an element 'desc'. As an example - if (iface->bInterfaceClass != USB_CLASS_HUB) + if (iface->desc.bInterfaceClass != USB_CLASS_HUB) This has been compile tested on MAKEALL arm, ppc and mips.

* stdio/device: rework function naming conventionJean-Christophe PLAGNIOL-VILLARD2009-07-18-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | So far the console API uses the following naming convention: ======Extract====== typedef struct device_t; int device_register (device_t * dev); int devices_init (void); int device_deregister(char *devname); struct list_head* device_get_list(void); device_t* device_get_by_name(char* name); device_t* device_clone(device_t *dev); ======= which is too generic and confusing. Instead of using device_XX and device_t we change this into stdio_XX and stdio_dev This will also allow to add later a generic device mechanism in order to have support for multiple devices and driver instances.
