From 212ea99a85d30dbc834888384c57ad5abbc67a0a Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Sun, 23 Sep 2012 16:58:49 +0000 Subject: phy/micrel: Implement support for KSZ8021 The KSZ8021 PHY was previously caught by KS8051, which is not correct. This PHY needs additional setup if it is strapped for address 0. In such case an reserved bit must be written in the 0x16, "Operation Mode Strap Override" register. According to the KS8051 datasheet, that bit means "PHY Address 0 in non-broadcast" and it indeed behaves as such on KSZ8021. The issue where the ethernet controller (Freescale FEC) did not communicate with network is fixed by writing this bit as 1. Signed-off-by: Marek Vasut Cc: David J. Choi Cc: David S.
