| | | | | | | | | | | | The patch adds the EHCI controller for the i.MX31 Soc. Signed-off-by: Stefano Babic <sbabic@denx.de>
* | usb: musb: only write CLRDATATOG when appropriateBryan Wu2010-10-13-7/+16
| | | | | | | | | | | | | | | | | | | | This is a change similar to what is already in the Linux driver. We should only program the CLRDATATOG bit when the current mode indicates that it is needed.

* | USB-CDC: Prevent rx_req being enqueued twiceVitaly Kuzmichev2010-10-13-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After gadget reinitializaton (after tftp has been done once) packet_received may become equal to 1 due to nuking OUT_EP while disabling it in eth_reset_config. rx_submit called from usb_eth_init queues rx_req first time. But the first call of usb_eth_recv from NetLoop queues rx_req again due to packet_received = 1. The following flow shows the path of functions calls when this happens: net/net.c:NetLoop | +-net/eth.c:eth_init | ether.c:usb_eth_init | | | +-udc_driver:usb_gadget_handle_interrupts | | udc_driver:... | | ether.c:eth_setup | | ether.c:eth_set_config | | ether.c:eth_reset_config | | udc_driver:usb_ep_disable | | udc_driver:nuke | | ether.c:rx_complete | | ether.c: packet_received = 1; | | | +-ether.c:rx_submit | udc_driver:usb_ep_queue --- The first time when rx_req is queued | +-net/eth.c:eth_rx ether.c:usb_eth_recv | +-udc_driver:usb_gadget_handle_interrupts | udc_driver:... --- no interrupts, returning +-ether.c: if (packet_received) { ... ether.c:rx_submit udc_driver:usb_ep_queue --- The second time!

* | USB-CDC: Fix tx/rx_req memory leaksVitaly Kuzmichev2010-10-13-13/+7
| | | | | | | | | | | | | | | | | | | | | | | | Remove and fix needless and destructive operations with tx/rx_req. 1) 'req' in rx_complete is always not NULL and always equals to rx_req 2) Free allocated tx_req if rx_req allocation has failed 3) Do not zero out tx/rx_req in usb_eth_init, leave this for eth_reset_config which will be called at the next use of usb0 4) Additional check in usb_eth_recv is not required Signed-off-by: Vitaly Kuzmichev <vkuzmichev@mvista.com>

* USB-CDC: called handle_interrupts inside usb_eth_sendStefano Babic2010-09-20-1/+9
| | | | | | | | | The patch removes an endless loop in the usb_eth_send if the tx_complete is not called before going in the loop. The driver interrupt routine is called allowing the driver to check if the TX is completed. Signed-off-by: Stefano Babic <sbabic@denx.de>
* USB-CDC: correct wrong alignment in ether.cStefano Babic2010-09-20-1/+1

* USB-CDC: change simple_strtol to simple_strtoulVitaly Kuzmichev2010-09-20-1/+1

* USB-CDC: ethernet error path potential oops fixVitaly Kuzmichev2010-09-20-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix potential oops on rare error path. The patch is based on commit e7b13ec9235b9fded90f826ceeb8c34548631351 (done by David Brownell <david-b@pacbell.net>) from linux-2.6.git. Description of the issue taken from linux kernel bugzilla: (https://bugzilla.kernel.org/show_bug.cgi?id=9594) The potential error can be tracked down as follows: (1) line 807: let the second conjunct on the "if" statment be false meaning "dev->status_ep" is null. This means the "if" evaluates to false. follow thru the code until... (2) line 808: usb_ep_disable(dev->status_ep) passes in a null argument, however "usb_ep_disable" cannot handle that: (from include/linux/usb/gadget.h) 191 static inline int 192 usb_ep_disable (struct usb_ep *ep) 193 { 194 return ep->ops->disable (ep); 195 } -- Signed-off-by: Vitaly Kuzmichev <vkuzmichev@mvista.com>

* drivers/usb/host/ohci-hcd: rename readl/writel to ohci_readl/ohci_writelBecky Bruce2010-06-30-80/+85
| | | | | | | | | This avoids a build warning that you see if anyone in the header chain has included io.h (which is coming shortly). The previous code redefined readl/writel; this patch renames it to be specific to ohci. The defines are also moved from ohci-hcd.c to ohci.h. Signed-off-by: Becky Bruce <beckyb@kernel.crashing.org>

| | | | | | | | | | | | | | | | MUSB PHY on OMAP3EVM Rev >= E uses external Vbus supply to support 500mA of power.We need to program MUSB PHY to use external Vbus for this purpose. Adding 'extvbus' member in musb_config structure which should be set by all the boards where MUSB interface is using external Vbus supply. Also added ULPI bus control register read/write abstraction for Blackfin processor as it doesn't have ULPI registers.

| | | | | | | | | | | Changed musb_config initialization for omap3.c, davinci.c and da8xx.c using name of structure fields. This would cause the uninitialized field to be null by default and thus would help in avoiding to init some flags required to be set only for a few selected platforms.

* USB OHCI support for at91sam9g45 SoCSergey Matyukevich2010-06-30-0/+14
| | | | | | | | | | Add USB OHCI support for at91sam9g45ekes/at91sam9m10g45ek boards. Note that according to errata from Atmel, OHCI is not operational on the first revision of at91sam9g45 chip. So this patch enables OHCI support for later revisions. Signed-off-by: Sergey Matyukevich <geomatsi@gmail.com>
* EHCI: zero out QH transfer overlay in ehci_submit_async()Sergei Shtylyov2010-06-29-2/+1
| | | | | | | | | | | | | | | | | | | | | ehci_submit_async() doesn't really zero out the QH transfer overlay (as the EHCI specification suggests) which leads to the controller seeing the "token" field as the previous call has left it, i.e.: - if a timeout occured on the previous call (Active bit left as 1), controller incorrectly tries to complete a previous transaction on a newly programmed endpoint; - if a halt occured on the previous call (Halted bit set to 1), controller just ignores the newly programmed TD(s) and the function then keeps returning error ad infinitum. This turned out to be caused by the wrong orger of the arguments to the memset() call in ehci_alloc(), so the allocated TDs weren't cleared either. While at it, stop needlessly initializing the alternate next TD pointer in the QH transfer overlay... Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Acked-by: Remy Bohmer <linux@bohmer.net>

| | | | | | | | | Commit b416191a14770c6bcc6fd67be7decf8159b2baee (Fix EHCI port reset.) didn't move the code that checked for successful clearing of the port reset bit from ehci_submit_root(), relying on wait_ms() call instead. The mentioned code also erroneously reported port reset state when the reset was already completed. Signed-off-by: Sergei Shtylyov <sshtylyov@mvista.com>
