Hello,
This question concerns the imx6qdl-tqma6x.dtsi file written by Sascha Hauer,
Pengutronix, but I don't know if he can answer.
Nevertheless, it could be a more general question : I want to know if the
32-bit words programmed in the following lines concern the
IOMUXC_SW_PAD_CTL_PAD registers that is to say IOMUXC_SW_PAD_CTL_PAD_GPIO5
and IOMUXC_SW_PAD_CTL_PAD_GPIO6 registers (Cf. theIMX6SDL Reference Manuel).
Because in the Reference Manuel bits 31-17 are reserved and always 0. Why is
there a '4' in these bits ? Or is it another register ?
-----------------------------------------------------------------------
i2c3 {
pinctrl_i2c3_2: i2c3grp-2 {
fsl,pins = <
MX6QDL_PAD_GPIO_5__I2C3_SCL 0x4001b8b1
MX6QDL_PAD_GPIO_6__I2C3_SDA 0x4001b8b1
>;
};
};
-----------------------------------------------------------------------
Best regards,
Sophie CARAYOL
