Added a new driver for the usb part of control module. This has an API to power on the USB2 phy and an API to write to the mailbox depending on whether MUSB has to act in host mode or in device mode. Also added an API to power on usb3 phy (omap5). Writing to control module registers for doing the above task which was previously done in omap glue and in omap-usb2 phy is removed. Changes from v2: * removed "ti,has_mailbox" and added "ti,type" to differentiate whether the control module has usb mailbox or usb3 phy power. omap4 has usb mailbox in control module to notify events to the musb core and omap5 has usb3 phy power register to power on usb3 phy. * Added an API to power on USB3 PHY needed for OMAP5. Changes from v1: * renamed get_omap_control_dev to omap_get_control_dev * created and exported a single API (omap_control_usb_set_mode) to change the usb mode * Before writing to the otghs_control regster, the value from otghs_control regster is read and only the appropriate bits are set. * In omap_init_control_usb, the indentation is now reduced as per Felipe's suggestion. Changes from RFC: * Used "#if IS_ENABLED(CONFIG_OMAP_CONTROL_USB)" instead of "#if (defined(CONFIG_OMAP_CONTROL_USB) || \ defined(CONFIG_OMAP_CONTROL_USB_MODULE))" * return "-EADDRNOTAVAIL" if devm_request_and_ioremap fails. * Removed the dt data from this patch series (I'll send that as a separate series). * added "ctrl_module" binding to usb otg glue and usb phy in the Documentaion. This binding is not planned to be used until an actual requirement for it arises. This series was developed on git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb.git xceiv I've kept this patch series and all the patch series to follow in a single branch git://gitorious.org/linux-usb/linux-usb.git omap5-with-palmas (changes up to 23b4dfa2ab7052569cd88acc6383c4b1a8e8a482) Did basic enumeration testing in omap4 panda, omap3 beagle and omap5 evm.
