I am using a custom i.MX6 Board and I am configuring pin multiplexing in device tree.

Can anyone tell me how this value is calculated

MX6QDL_PAD_GPIO_0__CCM_CLKO1    0x130b0

Same GPIO is configured in different ways in different dtsi

MX6QDL_PAD_SD1_DAT2__GPIO1_IO19          0x80000000
MX6QDL_PAD_SD1_DAT2__GPIO1_IO19         0x030b0

What I know is that we configuring the PAD SDA1_DAT2 to GPIO1_IO19 mode.. But why is the value different..

Thanks for your time
