* usb: add enum usb_init_type parameter to usb_lowlevel_initTroy Kisky2013-10-20-1/+1
| | | | | | This parameter will later be used to verify OTG ports. Signed-off-by: Troy Kisky <troy.kisky@boundarydevices.com>
* usb: Prevent using reserved registers on DM36x usbAndrew Murray2013-10-10-5/+14
| | | | | | | | | | | | | | | | The musb driver defines and uses MUSB_CSR0_H_DIS_PING, however this bit is reserved on the DM36x. Thus this patch ensures that the reserved bit is not accesssed. It has been observed that some USB devices will fail to enumerate with errors such as 'error in inquiry' without this patch. See http://www.ti.com/litv/pdf/sprufh9a for details.

* usb: Fix error handling in musb_hcd.cAndrew Murray2013-10-07-5/+5
| | | | | | | | | | | | | | | The wait_until_[rx|tx]ep_ready functions return a u8 to indicate success containing the value 0, 1 or -1. This patch changes the return type to an int to accommodate the negative return values. These functions are used in the file using calls such as if (!wait_until... Where a -1 is returned it is mishandled and treated as success instead of a CRC error. This patch addresses this.

* usb: use linux/usb/ch9.h instead of usbdescriptors.hIlya Yanok2012-11-20-2/+3
| | | | | | | | | | | | | | | | | | | | | | Linux usb/ch9.h seems to have all the same information (and more) as usbdescriptors.h so use the former instead of the later one. As a consequense of this change USB_SPEED_* values don't correspond directly to EHCI speed encoding anymore, I've added necessary recoding in EHCI driver. Also there is no point to put speed into pipe anymore so it's removed and a bunch of host drivers fixed to look at usb_device->speed instead. Old usbdescriptors.h included is not removed as it seems to be used by old USB device code. This makes usb.h and usbdevice.h incompatible. Fortunately the only place that tries to include both are the old MUSB code and it needs usb.h only for USB_DMA_MINALIGN used in aligned attribute on musb_regs structure but this attribute seems to be unneeded (old MUSB code doesn't support any DMA at all).

* usb: lowlevel interface change to support multiple controllersLucas Stach2012-10-15-2/+2
| | | | | | | | | | | Carry an index in the lowlevel usb functions to make specify the respective usb controller. Also pass through an controller struct from lowlevel_init to the creation of the root usb device of this controller.

* 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: 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 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.
