Hi, When running kernel 5.12-rc4 on imx6, video-mux fails to probe like this: [ 5.675490] video-mux: probe of 20e0000.iomuxc-gpr:ipu1_csi0_mux failed with error -107 [ 5.685226] video-mux: probe of 20e0000.iomuxc-gpr:ipu2_csi1_mux failed with error -107 I haven't started investigating this problem yet, but just wanted to let you know in case you have any suggestions. Thanks, Fabio Estevam
