Subject: realtek: rtl931x: Readd MAC_L2_GLOBAL_CTRL2 pinmux
X-Git-Url: http://git.openwrt.org/?a=commitdiff_plain;h=93113a745a24c114b9994b680ca290a00b0a7c1d;p=openwrt%2Fstaging%2Fthess.git

realtek: rtl931x: Readd MAC_L2_GLOBAL_CTRL2 pinmux

The MAC_L2_GLOBAL_CTRL2 register is primarily used for pin configuration.
It is necessary to select specific modes for pins or to free them for use
as GPIOs.
