From a1c76c150831168c09810006ede95b164fa292df Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Mon, 11 Jan 2016 22:41:25 -0800 Subject: net: tsec: Use priv->tbiaddr to initialize TBI PHY address Add a new member 'tbiaddr' to tsec_private struct. For non-DM driver, it is initialized as CONFIG_SYS_TBIPA_VALUE, but for DM driver, we can get this from device tree. Update the bindings doc as well.

These buses are defined +similarly to the mdio buses. The TBI PHYs underneath them are similar to +normal PHYs, but the reg property is considered instructive, rather than +descriptive. The reg property should be chosen so it doesn't interfere +with other PHYs on the bus. The TBI PHYs are referred to by a "tbi-handle" +property under the tsec node, which has a similar meaning of "phy-handle". + +Example: + ethernet@24000 { + phy-handle = <&tbi1>; + }; + + mdio@24520 { + tbi1: tbi-phy@1f { + reg = <0x1f>; + }; + }; -- cgit v1.1
