Marek Vasut aa5659ac65 arm: socfpga: scan: Clean up scan_chain_engine_is_idle() ... Rework this function so it's clear that it is only polling for certain bits to be cleared. Add kerneldoc. Fix it's return value to be either 0 on success and -ETIMEDOUT on error and propagate this through the scan manager code.
