* usb: Add usb phy to usb hostSascha Hauer2016-09-291-0/+1
| | | | | | | | Add a struct usb_phy * member to struct usb_host. Also, call usb_phy_notify_connect() / usb_phy_notify_disconnect() when there are connection changes on the root hub. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* usb: increase USB_CNTL_TIMEOUT to match linuxSteffen Trumtrar2015-05-041-1/+1
| | | | | | | | | | | | | | | | | | | | | USB requests should be processed within a timeframe of 5s. The linux kernel also uses this timeout value for the control packets. For the musb the increase in timeout helps successfully probing USB devices (at least on one test hardware), but on the other hand doesn't slow down the system, if there are no devices, i.e. the timeout never hits. That means, that the USB core correctly aborts instead of timing out. Why and how the 100ms was chosen in the first place, can not be deduced from the git history, just that it seems to work fine for most boards. Change USB_CNTL_TIMEOUT to 5000ms and replace all occurences of `USB_CNTL_TIMEOUT * x` with just `USB_CNTL_TIMEOUT`, as the timeout is now large enough without it.

* USB: Use descriptors from ch11.hSebastian Hesselbarth2014-07-241-26/+1
| | | | | | | | | Use the descriptors from ch11.h instead of duplicating them in usb.h. usb_hub_descriptor now contains a union .u to differentiate HS hub descriptor from SS hub descriptor.

* USB: host: drop force rescanSascha Hauer2014-07-181-3/+3
| | | | | | | | We can now detect changes in the USB device hierarchy properly, so the 'force' option to the usb command is no longer necessary. We just scan the busses each time the usb command is called. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* commands: usb: add tree view capabilityAntony Pavlov2014-07-181-0/+3

* USB: Remove conflicting USB_SPEED_* definitionsSascha Hauer2014-07-181-2/+0
| | | | | | | | | We have USB_SPEED_* definitions as macros in usb_defs.h and as an enum in ch9.h. The defines in usb.h correspond to hardware bits in the ehci controller. Get rid of them and keep the hardware independent enums. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* USB: Use descriptors from ch9.hSascha Hauer2014-07-181-62/+1

* USB: introduce usb_interface/usb_configuration structsSascha Hauer2014-07-181-17/+18
| | | | | | | | | | | Currently we have two conflicting definitions of struct usb_config_descriptor and struct usb_interface_descriptor in the tree. This is because the USB code uses additional fields in the structs for internal housekeeping. Add struct usb_interface and struct struct usb_configuration with the housekeeping data and embed the corresponding hardware structs into them. This frees the way to use the definitions from ch9.h in the next step. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* usb: implement a usb_host_detect to scan individual USB hostsSascha Hauer2013-06-211-0/+3

* | Change byte order detection mechanism to kernel styleSascha Hauer2012-06-281-2/+4
|/ | | | | | | | | | | | | | | The Linux Kernel defines only one of __LITTLE_ENDIAN and __BIG_ENDIAN. Endianess can then be tested with #ifdef __xx_ENDIAN. Userspace always defined both __LITTLE_ENDIAN and __BIG_ENDIAN and byteorder can then be tested with #if __BYTE_ORDER == __xx_ENDIAN. As we tend to use a lot of Kernel code in barebox we switch to use the kernel way of determing the byte order. As this always causes a lot of confusion add a check to include/common.h to make sure only one of __LITTLE_ENDIAN and __BIG_ENDIAN is defined. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
