Yes, but Jaswinder's changelog clearly shows that the runtime PM (and thus hwmod) init is not doing the equivalent of what was removed from the driver. A hunch after a quick glance is that the driver changes are only doing runtime PM calls on the UHH device and not the TTL device. In fact, the patch that builds the USB host omap_device[1] doesn't even build one. > moreover, the patch 'mfd: Add omap-usbhs runtime PM support' is > already reverted. It is reverted for this merge window, but will be added back for the next window, so Jaswinder's problem still needs to be fixed the right way. Please rework the USB host runtime PM conversion so that *all* the IP blocks are managed by runtime PM and the driver is doing runtime PM calls for all the devices used.
