Before /sys/kernel/debug/gpio output labels defined in the device tree, now it outputs the nodename of the device entry instead?! What gives?
there’s kernel version changed for your migration from rel-28 to rel-32, which kernel upgraded from kernel-4.4 to kernel-4.9.
may I know what’s your use-case,
I was toldf the answer! Instead of “label =” in the dts it’s now “line-name =”
