usb: tegra: ULPI regression on tegra20

2014-10-06T14:12:48+00:00

Trying to enumerate USB devices connected via ULPI to T20 failed as
follows:

USB2:   ULPI integrity check failed

Git bisecting revealed the following commit being at odds:

commit 2d34151f7501ddaa599897f0d89ad576126b03eb
usb: tegra: refactor PHY type selection

Looking at above commit one quickly identifies a copy paste error which
this patch fixes. Happy ULPIing again (;-p).

usb: ehci: Make periodic_schedules a per controller variable

2014-10-06T12:50:42+00:00

Periodic schedules tracks how many int_queue-s are active, and decides whether
or not to en/disable the periodic schedule based on this. This is clearly
a per controller thing.

usb: ehci: poll_int_queue check real qtd, not the overlay

2014-10-06T12:50:42+00:00

When we first start an int queue, the qh's overlay area is all zeros. This
gets filled by the hc with the actual qtd values as soon as it advances
the queue, but we may call poll_int_queue before then, in which case we
would think the transfer has completed as the hc has not yet copied the
qt_token to the overlay, so the active flag is not set.

This fixes this by checking the actual qtd token, rather then the overlay.
This also fixes a (theoretical) race where we see the completion in the
overlay and free and re-use the qtd before the hc has completed writing back
the overlay to the actual qtd.

usb: ehci: Properly set hub devnum and portnr with usb-1 hubs in the chain

2014-10-06T12:50:42+00:00

For full / low speed devices we need to get the devnum and portnr of the tt,
so of the first upstream usb-2 hub, not of the parent device (which may be a
usb-1 hub).

usb: ehci-mx6: Rename the USB register base address

2014-09-29T08:33:27+00:00

The mx6sl/mx6sx has 2 OTG and 1 host. So they have name
"USBO2H_USB_BASE_ADDR" in imx-regs.h. The driver hard codes
the USB base address name to "USBOH3", which causes the driver
failed to build for mx6sl/mx6sx.

This patch uniform the address name to "USB_BASE_ADDR" for all
mx6 series.

usb: ehci: mxs: Add board-specific callbacks

2014-09-29T07:02:16+00:00

Add board-specific callbacks for enabling/disabling port power
into the MXS EHCI controller driver. This is in-line with the
names of callbacks on other systems.

USB: ehci-atmel: use pcr to enable or disable clock

If the SoC has pcr, we use pcr (peripheral control register)
to enable or disable clock.
