2010-12-10usb: pch_udc: Fix setup transfers with data outRichard Röjfors1-1/+4
This patch fixes an issue where the driver does not handle out data in setup transactions. The per endpoint cached status register is cleared in the pch_udc_svc_control_out function. When there is out data available the function pch_udc_svc_data_out is called which tries to pick it up the status, which now is cleared to 0. When the status is 0, the function doesn't start reading the data from the FIFO. There is a second bug in all this, pch_udc_svc_data_out takes the endpoint number (0 for EP0), while pch_udc_svc_control_out passes the endpoint index (1 for EP0). Effectively pch_udc_svc_data_out picks up the wrong internal ep structure. This patch makes sure to put back the cached status and pass the endpoint number rather than index when calling pch_udc_svc_data_out.

2010-12-10USB: gadget: Introduce ci13xxx_udc_driver structPavankumar Kondeti3-55/+175
Introduces ci13xxx_udc_driver struct for bus glue drivers to hint ci13xxx_udc core about their special requirements. The flags include avoiding hardware register access when controller is not in peripheral mode, enabling pull-up upon VBUS, disabling streaming mode and dependency on transceiver driver. Initialize gadget_ops in udc_probe so that transceiver can notify VBUS presence even when no gadget driver is bounded. A notify_event callback is embedded in the same struct. This patch implements two events called CONTROLLER_RESET_EVENT and CONTROLLER_STOPPED_EVENT to notify the bus glue driver after resetting and stopping the controller for performing SoC specific quirks.

2010-12-10USB: EHCI: ASPM quirk of ISOC on AMD SB800Alex He4-0/+120
When ASPM PM Feature is enabled on UMI link, devices that use ISOC stream of data transfer may be exposed to longer latency causing less than optimal per- formance of the device. The longer latencies are normal and are due to link wake time coming out of low power state which happens frequently to save power when the link is not active. The following code will make exception for certain features of ASPM to be by passed and keep the logic normal state only when the ISOC device is connected and active. This change will allow the device to run at optimal performance yet minimize the impact on overall power savings.

Commit 06c3859 (usb: gadget/imx-udc: remove usage of deprecated symbol USBD_INT0) was a bit precipitant because the name used instead didn't match the usual naming scheme for irqs on arm/imx. I renamed the irq to the right name in e083000 (ARM: imx: dynamically allocate imx_udc device) when 06c3859 didn't hit Linus' tree, so I missed to add a compat #define.

2010-12-10usb: musb: Adding musb support for OMAP4430Hema HK2-11/+99
OMAP4430 supports UTMI and ULPI types of transceiver interface. In UTMI mode: The PHY is embedded within OMAP4430. The transceiver functionality is split between the twl6030 PMIC chip and OMAP4430. The VBUS, ID pin sensing and OTG SRP generation part is integrated in TWL6030 and UTMI PHY functionality is embedded within the OMAP4430. There is no direct interactions between the MUSB controller and TWL6030 chip to communicate the session-valid, session-end and ID-GND events. It has to be done through a software by setting/resetting bits in one of the control module register of OMAP4430 which in turn toggles the appropriate signals to MUSB controller. musb driver is register for blocking notifications from the transceiver driver to get the event notifications for connect/disconnect and ID-GND. Based on these events call the transceiver init/shutdown function to configure the transceiver to toggle the VBUS valid, session end and ID_GND signals to musb and power on/off the internal PHY. For ID_GND event notifications, toggle the ID_GND signal and then wait for musb to be configured as "A" device, and then call the transceiver function to set the VBUS. In OTG mode and musb as a host, When the Micro A connector used, VBUS is turned on and session bit set. When the device is connected, enumeration goes through. When the device disconnected from the other end of the connector(ID is still grounded), link will detect the disconnect and end the session. When the device is connected back, there are no events generated in the TWL6030-usb, and link is already down. So the device is not detected. Removed the session bit disable code which will recognize the connect of the device. Limitation: In OTG host mode, if device is connected during boot, it does not get detected. If disconnect and connect it back or connect after boot only it works. Fix for this, I will submit seperate patch later.

2010-12-10usb: otg: Adding twl6030-usb transceiver driver for OMAP4430Hema HK1-0/+493
Adding the twl6030-usb transceiver support for OMAP4 musb driver. OMAP4 supports 2 types of transceiver interface. 1. UTMI: The PHY is embedded within OMAP4. The transceiver functionality is split between the twl6030 PMIC chip and OMAP4430. The VBUS, ID pin sensing and OTG SRP generation part is integrated in TWL6030 and UTMI PHY functionality is embedded within the OMAP4430. There is no direct interactions between the MUSB controller and TWL6030 chip to communicate the session-valid, session-end and ID-GND events. It has to be done through a software by setting/resetting bits in one of the control module register of OMAP4430 which in turn toggles the appropriate signals to MUSB controller. The internal transceiver has functional clocks and powerdown bits to powerdown the PHY for power saving. Since there is no option available for having 2 transceiver drivers for one USB controller, internal PHY specific APIs are passed through plaform_data function pointers to use in the twl6030-usb transceiver driver. 2. ULPI interface is provided for off-chip transceivers.
