Beagle Bone Rev A5 serial communication UART4 and UART5 mux settings

I am working on Beagle Bone Rev A5 and my UART1 and UART2 are working fine with this mux setting:

echo 20 > /sys/kernel/debug/omap_mux/uart1_rxd
echo 0 > /sys/kernel/debug/omap_mux/uart1_txd
echo 1 > /sys/kernel/debug/omap_mux/spi0_d0
echo 21 > /sys/kernel/debug/omap_mux/spi0_sclk

Now i want a hardware flow control enabled and for that i want to use UART4 and UART5 can anybody help me enabling Rx,Tx,RTS,CTS of uart 4 & 5, what will be the mux setting for these UARTs?
