usb: chipidea: imx: Fix ULPI on imx53

2018-03-29T10:03:01+00:00

Traditionally, PORTSC should be set before initializing ULPI phys. But setting PORTSC before powering on the phy results in a kernel freeze on imx53 based GE PPD. As a workaround this initializes the phy early in the imx platform code and disables phy power management from the core.

usb: chipidea: usbmisc: evdo can be set e/o reset

2018-03-29T10:03:01+00:00

evdo bit can be set or reset. We can not trust evdo bit status after bootloader stage Signed-off-by: Michael Trimarchi Signed-off-by: Peter Chen Signed-off-by: Greg Kroah-Hartman

usb: chipidea: usbmisc: evdo is only specific to OTG port

2018-03-29T10:03:01+00:00

The USB_PHY_CTRL_FUNC is used specific for OTG port as described in user manual. EVDO need to be set only for index 0 that correspond to OTG port Signed-off-by: Michael Trimarchi Signed-off-by: Peter Chen Signed-off-by: Greg Kroah-Hartman

usb: add a flag to skip PHY initialization to struct usb_hcd

2018-03-09T17:43:52+00:00

The USB HCD core driver parses the device-tree node for "phys" and "usb-phys" properties. It also manages the power state of these PHYs automatically. However, drivers may opt-out of this behavior by setting "phy" or "usb_phy" in struct usb_hcd to a non-null value. An example where this is required is the "Qualcomm USB2 controller", implemented by the chipidea driver. The hardware requires that the PHY is only powered on after the "reset completed" event from the controller is received. A follow-up patch will allow the USB HCD core driver to manage more than one PHY. Add a new "skip_phy_initialization" bitflag to struct usb_hcd so drivers can opt-out of any PHY management provided by the USB HCD core driver. This also updates the existing drivers so they use the new flag if they want to opt out of the PHY management provided by the USB HCD core driver. This means that for these drivers the new "multiple PHY" handling (which will be added in a follow-up patch) will be disabled as well.

USB: chipidea: Re-use DEFINE_SHOW_ATTRIBUTE() macro

USB: move many drivers to use DEVICE_ATTR_WO

2018-01-24T07:49:52+00:00

Instead of "open coding" a DEVICE_ATTR() define, use the DEVICE_ATTR_WO() macro instead, which does everything properly instead. This does require a few static functions to be renamed to work properly, but thanks to a script from Joe Perches, this was easily done.
