Pad register value for i.mx6

deexithamba — Thu, 21 Feb 2019 06:38:05 GMT

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.

Hi Deexith

one can check linux documentation:

linux/Documentation/devicetree/bindings/pinctrl/fsl,imx6q-pinctrl.txt

fsl,imx6q-pinctrl.txt\pinctrl\bindings\devicetree\Documentation - linux-imx - i.MX Linux kernel

and sect.36.4.370 Pad Control Register (IOMUXC_SW_PAD_CTL_PAD_KEY_COL2)

i.MX6DQ Reference Manual
