Aug 12, 2020 · phandle access in kernel (by drivers) The "phandle" and "linux,phandle" properties may exist in device tree source and in the compiled Flattened Device Tree (FDT), aka "binary blob" or ".dtb". But the Linux kernel views the phandle values as device tree structure information instead of device tree data and thus does not store them as properties.
