3.16.55-rc1 review patch. If anyone has any objections, please let me know.
------------------ From: Florian Fainelli <[email protected]> commit e463d88c36d42211aa72ed76d32fb8bf37820ef1 upstream. RGMII interfaces come in 4 different flavors that the PHY library needs to care about: regular RGMII (no delays), RGMII with either RX or TX delay, and both. In order to avoid errors of checking only for one type of RGMII interface and miss the 3 others, introduce a convenience function which tests for all values. Suggested-by: David S.
