For device tree, we may be eventually able to handle the ctrl_register using pinctrl-single.c and pinconf API. It probably does not make sense to set it up as a regulator as the comparator can trigger errors also for the pinconf related bits at least for MMC PBIAS. > > Till then, where can I get a tree where musb works on Panda? On panda, without using device tree, use v3.7-rc2 + the following patches: ARM: OMAP: ocp2scp: create omap device for ocp2scp ARM: OMAP4: add _dev_attr_ to ocp2scp for representing usb_phy drivers: bus: ocp2scp: add pdata support Also you need to enable CONFIG_OMAP_USB2. No idea what all is needed to use MUSB with device tree at this point.
