Hi Akash,

I didn't see a patch that implements the binding, did you post it?

We haven't posted any update on patch@ 
https://patchwork.kernel.org/cover/11313817/

[tty: serial: qcom_geni_serial: Configure UART_IO_MACRO_CTRL register]. 
We will spin it ASAP.

Yeah ok, It is possible to derive value for rx-tx-cts-rts if above 2 
properties are set.
