*	ar71xx: rb493g: fix gpio-mdio accesses under load	Jonas Gorski	2015-06-17	1	-0/+61
	It seems that there are maximum timings for mdio accesses that can be hit when the system is under load and the thread is scheduled during a read or write access. Since there is no way of knowing if this happens as there is not even a parity bit, try to work around it by disabling interrupts during any gpio-mdio accesses. Performance impact seems to be neglectable, as mdio accesses are not that often. Hopefully fixes #19500. Signed-off-by: Jonas Gorski <jogo@openwrt.org> SVN-Revision: 46012
