Hi Rob,

thank you for RB,

i would change the drive-strength in the example also to 8 based on angelos [1] review in next version

+ mdio0_pins: mdio0-pins {
+ mux {
+ function = "eth";
+ groups = "mdc_mdio0";
+ };
+
+ conf {
+ pins = "SMI_0_MDC", "SMI_0_MDIO";
+ drive-strength = <MTK_DRIVE_8mA>;
+ };
+ };

to

+ mdio0_pins: mdio0-pins {
+ mux {
+ function = "eth";
+ groups = "mdc_mdio0";
+ };
+
+ conf {
+ pins = "SMI_0_MDC", "SMI_0_MDIO";
+ drive-strength = <8>;
+ };
+ };

can i leave your RB (so you do not need to look at it again) or drop it because i change the patch?

regards Frank
