The Blackfin implementation of musb has a TXCOUNT register that needs to be programmed when transmitting data. Signed-off-by: Bryan Wu <[email protected]> Signed-off-by: Cliff Cai <[email protected]> Signed-off-by: Mike Frysinger <[email protected]>
2010-08-12musb: am35x: Workaround for fifo read issueAjay Kumar Gupta
AM35x supports only 32bit read operations so we need to have workaround for 8bit and 16bit read operations. Signed-off-by: Ajay Kumar Gupta <[email protected]>

Fixes below compilation warning omap3.c: In function 'musb_platform_init': omap3.c:123: warning: implicit declaration of function 'omap3_evm_need_extvbus' Signed-off-by: Ajay Kumar Gupta <[email protected]> Acked-by: Remy Bohmer <[email protected]> Signed-off-by: Sandeep Paulraj <[email protected]>
2010-06-30drivers/usb/host/ohci-hcd: rename readl/writel to ohci_readl/ohci_writelBecky Bruce
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 <[email protected]>
2010-06-30musb: Program extvbus for OMAP3EVM Rev >= EAjay Kumar Gupta
OMAP3EVM Rev >=E uses external Vbus supply so setting 'extvbus' to '1' for OMAP3EVM Rev >=E runtime based on EVM revision. CC: Remy Bohmer <[email protected]> Signed-off-by: Ajay Kumar Gupta <[email protected]>
2010-06-30musb: Add Phy programming for using external VbusAjay Kumar Gupta
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.

2010-06-30musb: Use name based initialization for musb_configAjay Kumar Gupta
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.

2010-06-30USB OHCI support for at91sam9g45 SoCSergey Matyukevich
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 <[email protected]>
2010-06-29EHCI: zero out QH transfer overlay in ehci_submit_async()Sergei Shtylyov
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 <[email protected]> Acked-by: Remy Bohmer <[email protected]>

2010-04-08EHCI: fix port reset reportingSergei Shtylyov
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 <[email protected]>
2010-04-08EHCI: fix off-by-one error in ehci_submit_root()Sergei Shtylyov
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 <[email protected]>
2010-04-08EHCI: fix root hub device descriptorSergei Shtylyov
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 <[email protected]>
2010-04-03at91: use C structs for AT91 OHCI codeMatthias Fuchs
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 <[email protected]>

2010-02-03usb: musb: fix Blackfin DMA register paddingCliff Cai
The conversion from offsets to C structs lost a little padding in the DMA register map. Accessing endpoints other than ep0 with DMA would fail as the addresses wouldn't be adjusted correctly. Signed-off-by: Cliff Cai <[email protected]> Signed-off-by: Mike Frysinger <[email protected]>

Currently ppc440epx uses OHCI for USB full-speed support. This change adds support for EHCI. Signed-off-by: Chris Zhang <[email protected]>
2010-01-09Fix EHCI port reset.Chris Zhang
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 <[email protected]>

The RX Control/Status register has bits that we want to preserve, so don't just write out a single bit. Preserve the others bits in the process. The original code posted to the u-boot list had this behavior, but looks like it was lost somewhere along the way to merging.

2009-12-20USB Consolidate descriptor definitionsTom Rix
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.

2009-07-18stdio/device: rework function naming conventionJean-Christophe PLAGNIOL-VILLARD
So far the console API uses the following naming convention: ======Extract====== typedef struct device_t; int device_register (device_t * dev); int devices_init (void); int device_deregister(char *devname); struct list_head* device_get_list(void); device_t* device_get_by_name(char* name); device_t* device_clone(device_t *dev); ======= which is too generic and confusing. Instead of using device_XX and device_t we change this into stdio_XX and stdio_dev This will also allow to add later a generic device mechanism in order to have support for multiple devices and driver instances.
