From 0db7d253e9f0ff1a41c602429bea93df221be6ed Mon Sep 17 00:00:00 2001 From: Bryan Whitehead Date: Mon, 17 Dec 2018 16:44:50 -0500 Subject: lan743x: Expand phy search for LAN7431 The LAN7431 uses an external phy, and it can be found anywhere in the phy address space. This patch uses phy address 1 for LAN7430 only. And searches all addresses otherwise. Signed-off-by: Bryan Whitehead Reviewed-by: Andrew Lunn Signed-off-by: David S.
