Subject: mediatek: update pinconf for GL.iNet eMMC boards
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f7735158f36d11592f2df67bdb09d36af5a0572c;p=thirdparty%2Fopenwrt.git

mediatek: update pinconf for GL.iNet eMMC boards

Update the pin-configuration as well as maximum frequency for the eMMC
flash.

 - Use 26 MHz as the maximum clock of the eMMC memory
 - Configure 12mA as the pin drive-strength
 - Enable internal pull-reistors
