| * | | at91: at91-ohci: support overcurrent notificationThomas Petazzoni2011-09-101-9/+215
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several USB power switches (AIC1526 or MIC2026) have a digital output that is used to notify that an overcurrent situation is taking place. This digital outputs are typically connected to GPIO inputs of the processor and can be used to be notified of those overcurrent situations. Therefore, we add a new overcurrent_pin[] array in the at91_usbh_data structure so that boards can tell the AT91 OHCI driver which pins are used for the overcurrent notification, and an overcurrent_supported boolean to tell the driver whether overcurrent is supported or not. The code has been largely borrowed from ohci-da8xx.c and ohci-s3c2410.c. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com>
| * | | at91: ohci-at91: add vbus_pin_inverted platform attributeThomas Petazzoni2011-09-101-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The existing OHCI AT91 driver made the assumption that the enable input of the USB power switch was active low. However, some USB power switches such as the Micrel MIC2026-1 [1] have an active high input to enable the power. A new vbus_pin_inverted attribute is added to the at91_usbh_data structure so that board files can tell the OHCI driver if the vbus pin logic is active low or active high.

This is an optional implementation for the OF binding only. The other bindings just pass an invalid GPIO to the isp1760_register() routine. Example, usage in DTS: gpios = <&pio_isp1761rst_0 0 1>; to point to a GPIO controller from within the ISP1761 node: GPIO 0, active low.

Evidently when one of these controllers increments the frame-index register, it changes the three low-order bits (the microframe counter) before changing the higher order bits (the frame counter). If the register is read at just the wrong time, the value obtained is too low by 8. When the appropriate quirk flag is set, we work around this problem by reading the frame-index register a second time if the first value's three low-order bits are all 0. This gives the hardware a chance to finish updating the register, yielding the correct value.

The ICDI board can also be used stand-alone, for other boards and chips than the kit it came with. The ICDI has both old style 20-pin JTAG connector and new style JTAG/SWD 10-pin 1.27mm pitch connector. Tested with EK-LM3S9B90, where the BD-ICDI board is included.

This results in the controller being resumed but no device state change being noticed, at which point the controller is put back to sleep again. Since there doesn't seem to be any reliable way to identify the state change, just unconditionally resume the hub. It'll be put back to sleep in the near future anyway if there are no active devices attached to it.

External USB 3.0 hubs report these values through the SuperSpeed Capabilities descriptor in the BOS descriptor. Make the USB 3.0 roothub for the xHCI host behave like an external hub and return the BOS descriptors. The U1 and U2 exit latencies will vary across each host controller, so we need to dynamically fill those values in by reading the exit latencies out of the xHC registers. Make the roothub code in the USB core handle hub_control() returning the length of the data copied.
