++ * @op: accessor function (takes @addr as its only argument)
++ * @addr: Address to poll
++ * @val: Variable to read the value into
++ * @cond: Break condition (usually involving @val)
++ * @sleep_us: Maximum time to sleep between reads in us (0

++ * is used (see Documentation/timers/timers-howto.rst).
++ * @timeout_us: Timeout in us, 0 means never timeout
++ *
++ * Returns 0 on success and -ETIMEDOUT upon a timeout. In either
++ * case, the last read value at @addr is stored in @val. Must not
++ * be called from atomic context if sleep_us or timeout_us are used.
