Hi Chris, After merging the mmc tree, today's linux-next build (arm multi_v7_defconfig) failed like this: ERROR (phandle_references): Reference to non-existent node or label "pinctrl_usdhc4_1" ERROR: Input tree has errors, aborting (use -f to force output) make[2]: *** [arch/arm/boot/dts/imx6dl-sabresd.dtb] Error 2 ERROR (phandle_references): Reference to non-existent node or label "pinctrl_usdhc4_1" ERROR: Input tree has errors, aborting (use -f to force output) make[2]: *** [arch/arm/boot/dts/imx6q-sabresd.dtb] Error 2 Caused by commit fc4fafac9656 ("ARM: dts: sabresd: add usdhc4 support"). I have used the mmc tree from next-20131212 for today. -- Cheers, Stephen Rothwell
