usb: chipidea: Prevent unbalanced IRQ disable

2018-11-13T19:08:36Z

[ Upstream commit 8b97d73c4d72a2abf58f8e49062a7ee1e5f1334e ] 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: Always build ULPI code

2018-07-05T06:22:47Z

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.

The commit 4e88d4c08301 ("usb: add a flag to skip PHY initialization to struct usb_hcd") delete the assignment for hcd->usb_phy, it causes usb_phy_notify_connect{disconnect) are not called, the USB PHY driver is not notified of hot plug event, then the disconnection will not be detected by hardware.

USB: chipidea: no need to check return value of debugfs_create functions

2018-05-31T10:54:22Z

When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this. Acked-by: Peter Chen Signed-off-by: Greg Kroah-Hartman

usb: chipidea: Fix ULPI on imx51

2018-05-31T10:44:39Z

Workaround introduced for i.MX53 in be9cae2479f48 ("usb: chipidea: imx: Fix ULPI on imx53") seems to be applicable in case of i.MX51 as well. Running latest kernel on ZII RDU1 Board (imx51-zii-rdu1.dts) exhibits a kernel frozen on PORTSC access and applying the workaround resolves the issue.

usb: chipidea: imx: Fix ULPI on imx53

2018-03-29T10:03:01Z

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.
