Hi, Below are device tree are captured from imx8mp-evk.dts. I want to know if my custom board without HDMI, will below red color highlighted device tree still needed ?
&iomuxc {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_hog>;
pinctrl_hog: hoggrp {
fsl,pins = <
MX8MP_IOMUXC_HDMI_DDC_SCL__HDMIMIX_HDMI_SCL 0x400001c3
MX8MP_IOMUXC_HDMI_DDC_SDA__HDMIMIX_HDMI_SDA 0x400001c3
MX8MP_IOMUXC_HDMI_HPD__HDMIMIX_HDMI_HPD 0x40000019
MX8MP_IOMUXC_HDMI_CEC__HDMIMIX_HDMI_CEC 0x40000019
>;
};
};
Solved! Go to Solution.
if you don't use HDMI, just leave HDMI_DDC_SCL, HDMI_DDC_SDA, HDMI_HPD, HDMI_CEC unconnected, on SW, you can ignore them and disable the HDMI
Means can remove red highlighted part in imx8mp-evk.dts right ?
if you don't use these pad for other function you can remove it
