2013-08-26usb: Use well-known descriptor sizes when parsing configurationJulius Werner1-10/+4
The existing USB configuration parsing code relies on the descriptors' own length values when reading through the configuration blob. Since the size of those descriptors is always well-defined, we should rather use the known sizes instead of trusting device-provided values to be correct. Also adds some safety to potential out-of-order descriptors. Change-Id: I16f69dfdd6793aa0fe930b5148d4521f3e5c3090 Signed-off-by: Julius Werner <jwerner@chromium.org>

2013-07-30usb_hub: fix power cycling logicNikita Kiryanov1-2/+2
When power cycling the hub ports, a misbehaving port will prevent all ports from being powered on because we quit at the first sign of trouble. Skip problematic ports instead of failing the entire power on. Cc: Marek Vasut <marex@denx.de> Cc: Igor Grinberg <grinberg@compulab.co.il> Signed-off-by: Nikita Kiryanov <nikita@compulab.co.il>

2013-06-13usb: ehci: add Faraday USB 2.0 EHCI supportKuo-Jung Su1-1/+6
This patch adds support to both Faraday FUSBH200 and FOTG210, the differences between Faraday EHCI and standard EHCI are listed bellow: 1. The PORTSC starts at 0x30 instead of 0x44. 2. The CONFIGFLAG(0x40) is not only un-implemented, and also has its address space removed. 3. Faraday EHCI is a TDI design, but it doesn't compatible with the general TDI implementation found at both U-Boot and Linux. 4. The ISOC descriptors differ from standard EHCI in several ways. But since U-boot doesn't support ISOC, we don't have to worry about that. Signed-off-by: Kuo-Jung Su <dantesu@faraday-tech.com> CC: Marek Vasut <marex@denx.de>
2013-06-13usb: hub: make minimum power-on delay configurableKuo-Jung Su1-2/+6
This patch makes the minimum power-on delay for USB HUB become configurable. The original design waits at least 100 msec here, but some EHCI controlers(e.g. Faraday EHCI) are known to require much longer delay interval.

2013-05-06usb: hub: Parallelize power-cycling of root-hub portsVivek Gautam1-7/+12
Untill now we power-cycle (aka: disable power on a port and re-enabling again) one port at a time. Delay of 20ms for Port-power to change multiplies with number of ports in this case. So better we parallelize this process: disable power on all ports, wait for port-power to stabilize and then re-enable the power subsequently. Signed-off-by: Vivek Gautam <gautam.vivek@samsung.com>

2013-05-06usb: hub: Fix enumration timeoutVivek Gautam1-1/+0
Patch b6d7852c increases timeout for enumeration, taking worst case to be 10 sec. get_timer() api returns timestamp in milliseconds, which is what we are checking in the do-while() loop in usb_hub_configure() (get_timer(start) < CONFIG_SYS_HZ * 10). This should give us a required check for 10 seconds, and thereby we don't need to add additional mdelay of 100 microseconds in each cycle.

2012-12-17usbh/ehci: Increase timeout for enumerationVipin Kumar1-5/+28
The current logic reads the port status just once after usb_hub_power_on and expects the portstatus and portchange to report the connection status immediately and correctly. Few pen drives are not able to report both of them immediately ie. those pens report the connection change but not the connected state after the first read. This opportunity once lost is gone for ever because the u-boot, unlike linux or any other OS, works in polling mode. This patch modifies the logic to read the port status continuously until the portstatus and portchange both report a connection change as well as a connected state or no connection change and no connection. This logic is placed in a timeout of 10 sec. At the end of it, the pen drive would have either reported a ONE or a ZERO in bit 1 of portstatus as well as portchange. It enhances the set of pen drives which can eventually be detected by u-boot Note: This 10 second timeout is based purely on several experiments done with the broken pen drives Signed-off-by: Vipin Kumar <vipin.kumar@st.com> Acked-by: Igor Grinberg <grinberg@compulab.co.il>

Common code has a mdelay() func, so use that instead of the usb-specific wait_ms() func.

2012-03-03USB: relax usbcore reset timingsWolfgang Grandegger1-1/+4
Following the corresponding Linux code, this patch relaxes reset timings waiting at least 100ms after power to the ports. There are some reports that it helps make enumeration work better on some high speed devices. Furthermore, the wait is only done once after power has been enabled on all ports.
