usb: Explicitly include correct DT includes The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

usb: renesas: Fix refcount leak bug In usbhs_rza1_hardware_init(), of_find_node_by_name() will return a node pointer with refcount incremented. We should use of_node_put() when it is not used anymore.

usb: renesas_usbhs: Use renesas_usbhs_platform_info on of_device_id.data In device tree environment, the previous code allocates renesas_usbhs_platform_info by using devm_kzalloc() and then copies usbhs_of_data to the allocated memory. This reason is some values (e.g. .platform_callback.get_vbus) are overwritten by the driver, but the of_device_id.data is "const". Now the driver doesn't have such a code, so this patch uses renesas_usbhs_platform_info on of_device_id.data. Note that the previous code set the pdev->dev.platform_data pointer even if device tree environment, but the value is not used. So, this patch also remove such a code.

usb: renesas_usbhs: Add a common function for the .get_id All platform related codes (rcar[23].c and rza{2}.c) has its own .get_id function as "USBHS_GADGET". So, we can use a common function for it.

usb: renesas_usbhs: replace udelay() with usleep_range() According to Documentation/timers/timers-howto.txt, a driver should use usleep_range() instead of udelay() on NON-ATOMIC CONTEXT if "SLEEPING FOR ~USECS OR SMALL MSECS ( 10us - 20ms)". Since the .hardware_init() and .power_ctrl() will run on NON-ATOMIC CONTEXT, this patch replaces udelay() with usleep_range().
