pinnmux in imx8m

Hi ,

 

Can anyone let me know what are below tuples used in "pins-imx8mq.h" file?

"<mux_reg conf_reg input_reg mux_mode input_val>"

 

I have understood that mux_reg  is offset of mux reg and conf_reg is offset of pad reg, and also mux_mode is alt-mode used.

But what are input_reg and input_val?

 

Also let me know how values to particular pins are given in dts?

for example in below pins how 82 is decided?

MX8MQ_IOMUXC_ECSPI1_SCLK_ECSPI1_SCLK    0x82

 

Thanks and Regards,

Yashavantha
