Configure QUP3 as SPI interface

I want to use 2 SPI interfaces on db845c board out of this LS1 already used and I would like to use another SPI interface on LS1 connector and want configure QUP3 core as SPI interface for the same.

|GPIO_41|QUP_L0(3)|SPI_MISO|
|GPIO_42|QUP_L1(3)|SPI_MOSI|
|GPIO_43|QUP_L2(3)|SPI_SCLK|
|GPIO_44|QUP_L3(3)|SPI_CS|

What are the steps and software modification required to achieve this?

@Loic could you please help me on this topic?

I would like to know software modification list to be done to make use of this GPIO as SPI interface.
