Yes, but since the associated peripheral is disabled, the users are free 
to configure other functions/peripherals, right? I mean something like 
this in pseudo-DT:

 /soc/pio: pinctrl@01c20800/uart1_pins:
   allwinner,pins = "PG6, PG7";
 /soc/pio: pinctrl@01c20800/foo0_pins:
   allwinner,pins = "PG6, PG7";
   ..
 /soc/uart1: serial@serial@01c28400:
   pinctrl-0 = <&uart1_pins>;
   status = "disabled";
 /soc/bar:
   pinctrl-0 = <&uart1_pins>;
   status = "disabled";

Assuming Linux/DT allows this, this would force nothing, only offer 
choice and ease of use.

Best,

Jorik
