usb: xhci: (likely) fix bracket in if condition

2014-06-25T20:43:16+00:00

Because of the brackets the & and && is evaluated before
the comparison. This is likely not the intention. Change
it to test the first and second condition to both be true.

usb: r8a66597: Fix initilization size of r8a66597 info structure

2014-06-25T20:38:04+00:00

Initialization of r8a66597 info structure is not enough.
Because initilization was used size of pointer.
This fixes that use size of r8a6659 info structure.

usb: r8a66597: Fix initialization hub that using R8A66597_MAX_ROOT_HUB

2014-06-25T20:31:41+00:00

This driver is processed as two USB hub despite one.
The number of root hub is defined in R8A66597_MAX_ROOT_HUB.
This fixes that register is accessed by using the definition
of R8A66597_MAX_ROOT_HUB.

usb: tegra: support device mode

2014-05-14T22:21:17+00:00

A few changes are made to the Tegra EHCI driver so that it can set
everything up for device-mode operation on the first USB controller.
This can be used in conjunction with ci_udc.c to operate as a USB
device.

Detailed changes are:

* Rename set_host_mode() to set_up_vbus() since that's really what it
  does.

* Modify set_up_vbus() to know whether it's initializing in host or
  device mode, and:

  - Skip the external VBUS check in device mode, since external VBUS is
    expected in this case.

  - Disable VBUS output in device mode.

* Modify init_phy_mux() to know whether it's initializing in host or
  device mode, and hence skip setting USBMODE_CM_HC (which enables host
  mode) in device mode. See the comments in that function for why this
  is safe w.r.t. the ordering requirements of PHY selection.

* Modify init_utmi_usb_controller() to force "b session valid" in device
  mode, since the HW requires this. This is done in UTMI-specific code,
  since we only support device mode on the first USB controller, and that
  controller can only talk to a UTMI PHY.

* Enhance ehci_hcd_init() to error-check the requested host-/device-mode
  vs. the dr_mode (dual-role mode) value present in device tree, and the
  HW configurations which support device mode.

* Enhance ehci_hcd_init() not to skip HW initialization when switching
  between host and device mode on a controller. This requires remembering
  which mode the last initialization used.

usb: tegra: refactor PHY type selection

2014-05-14T22:21:17+00:00

Both init_{utmi,ulpi}_usb_controller() have nearly identical code for
PHY type selection. Pull this out into a common function to remove the
duplication.
