2012-03-03USB: move keyboard polling into kbd driveramartin@nvidia.com
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>

2011-06-25musb: process control messages after roothub accepted itCliff Cai
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>
2011-04-02usb: musb: blackfin: check anomaly workarounds at runtime tooMike Frysinger
The anomaly workarounds we need for older silicon might break things if used on newer versions where the anomalies don't exist. So check the silicon rev at runtime too. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-04-02usb: musb: blackfin: make clkin configurableMike Frysinger
Not everyone has a 24MHz clkin to the USB, so let board porters override. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-11-17Switch from archive libraries to partial linkingSebastien Carlier
Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>

2010-10-13usb: musb: only write CLRDATATOG when appropriateBryan Wu
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.

2010-09-20usb: musb: stub out MUSB_TXCSR_MODE for Blackfin partsMike Frysinger

2010-06-30musb: Add Phy programming for using external VbusAjay Kumar Gupta
MUSB PHY on OMAP3EVM Rev >= E uses external Vbus supply to support 500mA of power.We need to program MUSB PHY to use external Vbus for this purpose. Adding 'extvbus' member in musb_config structure which should be set by all the boards where MUSB interface is using external Vbus supply. Also added ULPI bus control register read/write abstraction for Blackfin processor as it doesn't have ULPI registers.

2010-06-30musb: Use name based initialization for musb_configAjay Kumar Gupta
Changed musb_config initialization for omap3.c, davinci.c and da8xx.c using name of structure fields. This would cause the uninitialized field to be null by default and thus would help in avoiding to init some flags required to be set only for a few selected platforms.

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.

2009-12-20USB Consolidate descriptor definitionsTom Rix
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.

2009-07-17stdio/device: rework function naming conventionJean-Christophe PLAGNIOL-VILLARD
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.
