Subject: mediatek: filogic: mt-stuart: move AQR113C reset to MDIO bus level
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cb158aba32366d85616aa9d8f0e220d99f36155e;p=thirdparty%2Fopenwrt.git

mediatek: filogic: mt-stuart: move AQR113C reset to MDIO bus level

Each board wires one reset line that resets the AQR113C PHYs as a
group: GPIO 71 on SDG-8733/SDG-8734 and GPIO 62 on SDG-8733A.
Describe that line as the MDIO bus reset with the same assert and
deassert times.

Drop the per-PHY reset-gpios. On SDG-8733 the second AQR113C
claimed GPIO 62, which is not connected on that board.
