Pad register value for i.mx6

[deexithamba]

Hii,

How do we determine/set the value of pad register value in dtsi file?? I mean how do we calculate it exactly??

For example, 

MX6QDL_PAD_KEY_COL2__FLEXCAN1_TX    0x1b0b0,

On which factor is the 0x1b0b0 value set ??

Can anyone explain this with one example!!

Regards,

Deexith

Have you read the IOMUX Controller chapter in the reference manual? It explains the meaning of each field in the pad control register. For your example you can search for IOMUXC_SW_PAD_CTL_PAD_KEY_COL2.
