2008-09-09Make usb-stop() safe to call multiple times in a row.Remy Bohmer
A recent commit (936897d4d1365452bbbdf8430db5e7769ef08d38) enabled the usb_stop() command in common/cmd_bootm.c which was not enabled for some time, because no board did actually set the CFG_CMD_USB flag. So, now the usb_stop() is executed before loading the linux kernel. However, the usb_ohci driver hangs up (at least on AT91SAM) if the driver is stopped twice (e.g. the peripheral clock is stopped on AT91). If some other piece of code calls usb_stop() before the bootm command, this command will hangup the system during boot. (usb start and stop is typically used while booting from usb memory stick) But, stopping the usb stack twice is useless anyway, and a flag already existed that kept track on the usb_init()/usb_stop() calls. So, we now check if the usb stack is really started before we stop it. This problem is now fixed in both the upper as low-level layer.

2008-09-06USB EHCI: reset root hubYuri Tikhonov
Some of multi-function USB controllers (e.g. ISP1562) allow root hub resetting only via EHCI registers. So, this patch adds the corresponding kind of reset to OHCI's hc_reset() if the newly introduced CONFIG_PCI_EHCI_DEVNO option is set (e.g. for Socrates board).

2008-08-31USB: Add support for OHCI controller on S3C6400Guennadi Liakhovetski
Notice: USB on S3C6400 currently works _only_ with switched off MMU. One could try to enable the MMU, but map addresses 1-to-1, and disable data cache, then it should work too and we could still profit from instruction cache. Signed-off-by: Guennadi Liakhovetski <lg@denx.de>

When building the 8544DS board we get this error: In file included from r8a66597-hcd.c:22: u-boot/include/usb.h:190:2: error: #error USB Lowlevel not defined make[1]: *** [r8a66597-hcd.o] Error 1 The cleanest fix is to only build r8a66597-hcd.c if CONFIG_USB_R8A66597_HCD is set.

2008-07-10fix USB devices with multiple configurationsHarald Welte
This patch fixes bugs in usbdcore*.c related to the use of devices with multiple configurations. The original code made mistakes about the meaning of configuration value and configuration index, and the resulting off-by-one errors resulted in: * SET_CONFIGURATION always selected the first configuration, no matter what wValue is being passed. * GET_DESCRIPTOR/CONFIGURATION always returned the descriptor for the first configuration (index 0).

2008-05-21Big white-space cleanup.Wolfgang Denk
This commit gets rid of a huge amount of silly white-space issues. Especially, all sequences of SPACEs followed by TAB characters get removed (unless they appear in print statements). Also remove all embedded "vim:" and "vi:" statements which hide indentation problems. Signed-off-by: Wolfgang Denk <wd@denx.de>

2008-03-15usb: Add CFG_OHCI_USE_NPS to common USB-OHCI driverStefan Roese
This patch adds CFG_OHCI_USE_NPS to the common USB-OHCI driver. This way a board just needs to define this new option to enable the "force NoPowerSwitching mode" instead of adding new CPU/architecture defines to the USB source itself. This new option will be used first with the new AMCC 460EX Canyonlands board port, which will be posted in a few days. This patch also fixes a small compilation problem when DEBUG is enabled.
