+If the pin controller on the platform can support both pinmux and GPIO
+control such as the most of MediaTek platform. Please use below properties.
+
 - pinctrl-names: Should be "default", "runtime"
 - pinctrl-0: Should contain UART RXD low when the device is powered up to
 	     enter proper bootstrap mode.
 - pinctrl-1: Should contain UART mode pin ctrl
 
+Else, the pin controller on the platform only can support pinmux control and
+the GPIO control still has to rely on the dedicated GPIO controller such as
+a legacy MediaTek SoC, MT7621. Please use the below properties.
+
+- boot-gpios:	GPIO same to the pin as UART RXD and used to keep LOW when
+		the device is powered up to enter proper bootstrap mode when
+- pinctrl-names: Should be "default"
+- pinctrl-0: Should contain UART mode pin ctrl
+
 Optional properties:
 
 - reset-gpios:	GPIO used to reset the device whose initial state keeps low,
 		if the GPIO is missing, then board-level design should be
 		guaranteed.
+- clocks:	Should be the clock specifiers corresponding to the entry in
+		clock-names property. If the clock is missing, then board-level
+		design should be guaranteed.
+- clock-names:	Should contain "osc" entry for the external oscillator.
 - current-speed:  Current baud rate of the device whose defaults to 921600
