Linux/AM3358: UART4 pinmux

Part Number: AM3358

Tool/software: Linux

hello everybody
 
this is regarding the AM335X datasheet UART4 configuration 
if you see here UART4_RXD,UART4_TXD can be configured in device tree on pin E18,E17 and also on T17 and U17 as shown in green and red circle
my doubt:
  • is it possible to configure UART4 on Pin E18 ,E17 as RS232 and UART4 on pin T17,U17 as RS485 in device tree or do you think it is not possible

assume that we will connect E18,E17 to RS232 phy chip and T17,U17 to RS485 phy chipset
