Ok. I will provide dual license in v2.

Ok.

Could you be more specific here?

The 0x80000000 corresponds to IMX_NO_PAD_CTL in pinctrl-imx.c, which
prevents from manual GPIO control.

The 0x80000000 value is the IOMUXC_SW_PAD_CTL_PAD_CSI0_DATA11
(0x020E_0654) config data (16 bits only -> 0x0).

Writing 0x0 to this register is perfectly fine for my application.


I'm a bit in doubt to what I shall do more?
