* | ehci-hcd: fix memory leak in lowlevel initNikita Kiryanov2013-07-29-1/+3
| | | | | | | | | | | | | | | | | | | | usb_lowlevel_init() allocates a new periodic_list each time it is invoked, without freeing the original list. Since it is initialized later on in the code, just reuse the first-allocated list in future invocations of usb_lowlevel_init.

* | usb: ehci-omap: Don't softreset USB High-speed Host (UHH) ModuleRoger Quadros2013-07-29-12/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes NFS root problems with Beagle (3530 ES1.0) when used with external USB-ethernet adapter and "USB start" command used within u-boot. Soft resetting the UHH module causes instability issues on all OMAPs so we just avoid it. See OMAP36xx Errata i571: USB host EHCI may stall when entering smart-standby mode i660: USBHOST Configured In Smart-Idle Can Lead To a Deadlock On OMAP4/5, soft-resetting the UHH module can put it into Smart-Idle mode and lead to a deadlock. On OMAP3 this doesn't seem to be the case but still instabilities are observed on beagle (3530 ES1.0) if soft-reset is used. e.g. NFS root failures with Linux kernel.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The usb_lowlevel_init() call already fills and passes back struct ehci_ctrl , which readily contains correctly determined address of the port register block address computed from values from controller configuration registers. Leverage this and make use of this value as this makes the code mode universal, but also gets us rid of the CONFIG_USB_REG_BASE configuration option. Moreover, this patch cleans up the usb_gadget_register_driver() call a little by correcting the error handling. Note the usb_lowlevel_init() and mvudc_probe() are now called in reversed order, but this has no impact on the code.

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.

* | usb: asix: Move software resets to basic_initJulius Werner2013-06-12-23/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ASIX driver calls a basic_init() function during get_info(), so that not all initialization tasks need to be redone on every init(). Unfortunately, the most important one is still triggered too often: the driver does a full port and MII reset on every asix_init(), requiring up to several seconds to reestablish the link. This patch confines that software reset into the asix_basic_init() function so that it will only be executed once. This saves about a second of boot time on systems using BOOTP. Note: this patch was previously submitted many moons ago as: usb: usbeth: asix: Do a fast init if link already established That patch seens to have been lost or forgotten, so this is a rebased version. It is tested on snow with a Asix USB dongle (Cisco).

* | usb: Correct CLEAR_FEATURE code in ehci-hcdSimon Glass2013-06-12-4/+6
|/ | | | | | | | | | | | | | | This commit broke USB2 on link (Chromebook Pixel): 020bbcb usb: hub: Power-cycle on root-hub ports However the root cause seems to be a missing mask and missing 'break' in ehci-hcd.c. This patch fixes both. On link, 'usb start' with a USB keyboard and memory stick inserted now finds both. The keyboard works as expected. Also ext2ls shows a directory listing from the memory stick.
