Hi Saravana et al., FYI the patch: 6b2117ad65f1bca9ece6d4b1ee784b42701a2d86 of: property: fw_devlink: Add support for "resets" and "pwms" Allows better tracking of dependencies between devices. drivers/of/property.c | 4 ++++ breaks v4l2 video devices on an i.MX6 CPU. The /dev/video* nodes are not created, and the drivers (async subdevicess) are "waiting": # cat /sys/kernel/debug/v4l2-async/pending_async_subdevices imx-media: [fwnode] dev=nil, node=/soc/ipu@2400000/port@0 [fwnode] dev=nil, node=/soc/ipu@2400000/port@1 [fwnode] dev=nil, node=/soc/ipu@2800000/port@0 [fwnode] dev=nil, node=/soc/ipu@2800000/port@1 imx6-mipi-csi2: [fwnode] dev=0-0036, node=/soc/bus@2100000/i2c@21a0000/camera@36 ipu2_csi1_mux: ipu1_csi0_mux: [fwnode] dev=21dc000.mipi, node=/soc/bus@2100000/mipi@21dc000 Reverting the patch (or commenting the "resets" out) fixes the problem: # cat /sys/kernel/debug/v4l2-async/pending_async_subdevices ipu2_csi1: ipu2_csi0: ipu1_csi1: ipu1_csi0: imx-media: imx6-mipi-csi2: ipu2_csi1_mux: ipu1_csi0_mux: What now? -- Krzysztof "Chris" Hałasa Sieć Badawcza Łukasiewicz Przemysłowy Instytut Automatyki i Pomiarów PIAP Al.
