3.11.10.14 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Linus Walleij <linus.walleij@xxxxxxxxxx> commit 82363cf2eeafeea6ba88849f5e2febdc8a05943f upstream. There is a regression in the upcoming v3.16-rc1, that is caused by a problem that has been around for a while but now finally hangs the system. The bootcrawl looks like this: pinctrl-nomadik soc:pinctrl: pin GPIO256_AF28 already requested by a03e0000.usb_per5; cannot claim for musb-hdrc.0.auto pinctrl-nomadik soc:pinctrl: pin-256 (musb-hdrc.0.auto) status -22 pinctrl-nomadik soc:pinctrl: could not request pin 256 (GPIO256_AF28) from group usb_a_1 on device pinctrl-nomadik musb-hdrc musb-hdrc.0.auto: Error applying setting, reverse things back HS USB OTG: no transceiver configured musb-hdrc musb-hdrc.0.auto: musb_init_controller failed with status -517 platform musb-hdrc.0.auto: Driver musb-hdrc requests probe deferral (...) The ux500 MUSB driver propagates the OF node to the dynamically created musb-hdrc device, which is incorrect as it makes the OF core believe there are two devices spun from the very same DT node, which confuses other parts of the device core, notably the pin control subsystem, which will try to apply all the pin control settings also to the HDRC device as it gets instantiated. (The OMAP2430 for example, does not set the of_node member.)
