This adds two functions to get DT properties "mentor,power" and "dr_mode": musb_get_power() and musb_get_mode() Signed-off-by: Petr Kulhavy <petr@xxxxxxxxx> --- v4: <initial> - created musb_get_dr_mode() v5: - musb_get_dr_mode() renamed to musb_get_mode() - added musb_get_power() v6: - musb_get_power() : added missing boundary check for the maximum value 510mA - formatting - added empty implementation of musb_get_power() v7: - removed empty implementation of musb_get_power() - musb_get_mode() returns MUSB_OTG if the property is not found

Now that you hard-coded the value, you don't need this function any more. [...] MBR, Sergei -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
