 /**
- * wait_for_bit()	waits for bit set/cleared in register

- * Function polls register waiting for specific bit(s) change
- * (either 0->1 or 1->0). It can fail under two conditions:
- * - Timeout
- * - User interaction (CTRL-C)
- * Function succeeds only if all bits of masked register are set/cleared
- * (depending on set option).
- *
- * @param prefix	Prefix added to timeout messagge (message visible only
- *			with debug enabled)
- * @param reg		Register that will be read (using readl())
- * @param mask		Bit(s) of register that must be active
- * @param set		Selects wait condition (bit set or clear)
- * @param timeout_ms	Timeout (in miliseconds)
- * @param breakable	Enables CTRL-C interruption
- * @return		0 on success, -ETIMEDOUT or -EINTR on failure
