usb: chipidea: Fix otg event handler

2018-09-20T09:04:22+00:00

At OTG work running time, it's possible that several events need to be addressed (e.g. ID and VBUS events). The current implementation handles only one event at a time which leads to ignoring the other one. Fix it. Signed-off-by: Loic Poulain Signed-off-by: Peter Chen

usb: chipidea: Prevent unbalanced IRQ disable

2018-09-20T09:04:21+00:00

The ChipIdea IRQ is disabled before scheduling the otg work and re-enabled on otg work completion. However if the job is already scheduled we have to undo the effect of disable_irq int order to balance the IRQ disable-depth value.

usb: chipidea: Add dynamic pinctrl selection

2018-09-20T09:04:21+00:00

Some hardware implementations require to configure pins differently according to the USB role (host/device), this can be an update of the pins routing or a simple GPIO value change. This patch introduces new optional "host" and "device" pinctrls. If these pinctrls are defined by the device, they are respectively selected on host/device role start. If a default pinctrl exist, it is restored on host/device role stop. Signed-off-by: Loic Poulain Signed-off-by: Peter Chen

usb: chipidea: imx: enable OTG overcurrent in case USB subsystem is already started

2018-09-20T09:04:21+00:00

When initializing the USB subsystem before starting the kernel, OTG overcurrent detection is disabled. In case the OTG polarity of overcurrent is low active, the overcurrent detection is never enabled again and events cannot be reported as expected. Because imx usb overcurrent polarity is low active by default, only detection needs to be enable in usbmisc init function. Signed-off-by: Nicolas Adell Signed-off-by: Peter Chen

usb: chipidea: imx: do not use preprocessor conditionals for PM

2018-09-20T09:04:21+00:00

Use preprocessor conditionals for CONFIG_PM and CONFIG_PM_SLEEP is not necessary since SET_SYSTEM_SLEEP_PM_OPS and SET_RUNTIME_PM_OPS does that internally. It is also the preferred way according to our coding style guidelines. Signed-off-by: Marcus Folkesson Signed-off-by: Peter Chen

usb: chipidea: Always build ULPI code

2018-07-05T06:22:47+00:00

Commit 03e6275ae381 ("usb: chipidea: Fix ULPI on imx51") causes a kernel hang on imx51 systems that use the ULPI interface and do not select the CONFIG_USB_CHIPIDEA_ULPI option. In order to avoid such potential misuse, let's always build the chipidea ULPI code into the final ci_hdrc object. Tested on a imx51-babbage board.
