2019-06-26usb: renesas_usbhs: Use renesas_usbhs_platform_info on of_device_id.dataYoshihiro Shimoda
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.

2019-06-26usb: renesas_usbhs: Add a common function for the .get_idYoshihiro Shimoda
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. Signed-off-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2019-01-18usb: renesas_usbhs: replace udelay() with usleep_range()Yoshihiro Shimoda
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().
