And if really so, there may be a corner case we missed. Oops, I found out one error at the boot log, http://storage.kernelci.org/next/next-20151120/arm-multi_v7_defconfig+CONFIG_LKDTM=y/lab-collabora/boot-exynos5800-peach-pi.html The boot log says, [ 5.754493] vdd_ldo9: supplied by vdd_2v [ 5.765510] of_graph_get_next_endpoint(): no port node found in /dp-controller@145B0000 Seems this error is because exynos5800-peach-pit.dts file doesn't have 'ports' node in dp node. Below is dp node description of exynos5420-peach-pit.dts file. &dp { status = "okay"; pinctrl-names = "default"; pinctrl-0 = <&dp_hpd_gpio>; samsung,color-space = <0>; samsung,dynamic-range = <0>; samsung,ycbcr-coeff = <0>; samsung,color-depth = <1>; samsung,link-rate = <0x06>; samsung,lane-count = <2>; samsung,hpd-gpio = <&gpx2 6 GPIO_ACTIVE_HIGH>; ports { port@0 { dp_out: endpoint { remote-endpoint = <&bridge_in>; }; }; }; }; And below is for exynos5800-peash-pit.dts, &dp { status = "okay"; pinctrl-names = "default"; pinctrl-0 = <&dp_hpd_gpio>; samsung,color-space = <0>; samsung,dynamic-range = <0>; samsung,ycbcr-coeff = <0>; samsung,color-depth = <1>; samsung,link-rate = <0x0a>; samsung,lane-count = <2>; samsung,hpd-gpio = <&gpx2 6 GPIO_ACTIVE_HIGH>; panel = <&panel>; }; Thanks, Inki Dae > > Thanks, > Inki Dae > >> >> Best regards, >> -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
