* 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>
* 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>

* EHCI: fix port reset reportingSergei Shtylyov2010-04-08-15/+17
| | | | | | | | | 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>
* EHCI: fix off-by-one error in ehci_submit_root()Sergei Shtylyov2010-04-08-1/+1
| | | | | | | | | | | USB devices on the 2nd port are not detected and I get the following message: The request port(1) is not configured That's with default CONFIG_SYS_USB_EHCI_MAX_ROOT_PORTS value of 2. 'req->index' is 1-based, so the comparison in ehci_submit_root() can't be correct. Signed-off-by: Sergei Shtylyov <sshtylyov@mvista.com>
* EHCI: fix root hub device descriptorSergei Shtylyov2010-04-08-2/+2
| | | | | | | | On little endian machines, EHCI root hub's USB revision is reported as 0.2 -- cpu_to_le16() was missed in the initializer for the 'bcdUSB' descriptor field. The same should be done for the 'bcdDevice' field. Signed-off-by: Sergei Shtylyov <sshtylyov@mvista.com>
* at91: use C structs for AT91 OHCI codeMatthias Fuchs2010-04-03-15/+13
| | | | | | | | | | | | This patch is part of migrating the AT91 support towards using C struct for all SOC access. It removes one more CONFIG_AT91_LEGACY warning. at91_pmc.h needs cleanup after migration of the drivers has been done. Signed-off-by: Matthias Fuchs <matthias.fuchs@esd.eu>

* Add ppc440epx USB ehci support.Chris Zhang2010-01-09-0/+49

* Fix EHCI port reset.Chris Zhang2010-01-09-0/+3
| | | | | | | | | In USB ehci driver, the port reset is not terminated. EHCI spec says "A host controller must terminate the reset and stabilize the state of the port within 2 milliseconds". Without termination, a port stays at reset state. This is observed on ppc4xx(sequoia) boards. Signed-off-by: Chris Zhang <chris@seamicro.com>
* USB Consolidate descriptor definitionsTom Rix2009-12-20-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The header files usb.h and usbdescriptors.h have the same nameed structure definitions for usb_config_descriptor usb_interface_descriptor usb_endpoint_descriptor usb_device_descriptor usb_string_descriptor These are out right duplicates in usb.h usb_device_descriptor usb_string_descriptor This one has extra unused elements usb_endpoint_descriptor unsigned char bRefresh unsigned char bSynchAddress; These in usb.h have extra elements at the end of the usb 2.0 specified descriptor and are used. usb_config_descriptor usb_interface_descriptor The change is to consolidate the definition of the descriptors to usbdescriptors.h. The dublicates in usb.h are removed. The extra element structure will have their name shorted by removing the '_descriptor' suffix. So usb_config_descriptor -> usb_config usb_interface_descriptor -> usb_interface For these, the common descriptor elements are accessed now by an element 'desc'. As an example - if (iface->bInterfaceClass != USB_CLASS_HUB) + if (iface->desc.bInterfaceClass != USB_CLASS_HUB) This has been compile tested on MAKEALL arm, ppc and mips.

* Add a unified s3c24x0 header filekevin.morfitt@fearnside-systems.co.uk2009-11-27-2/+1
| | | | | | | | | | This patch adds a unified s3c24x0 cpu header file that selects the header file for the specific s3c24x0 cpu from the SOC and CPU configs defined in board config file.
