From 220669495bf8b68130a8218607147c7b74c28d2b Mon Sep 17 00:00:00 2001 From: Andy Fleming Date: Wed, 4 Jan 2012 15:28:31 -0600 Subject: [PATCH] powerpc: Add TBI PHY node to first MDIO bus Systems which use the fsl_pq_mdio driver need to specify an address for TBI PHY transactions such that the address does not conflict with any PHYs on the bus (all transactions to that address are directed to the onboard TBI PHY). The driver used to scan for a free address if no address was specified, however this ran into issues when the PHY Lib was fixed so that all MDIO transactions were protected by a mutex. As it is, the code was meant to serve as a transitional tool until the device trees were all updated to specify the TBI address. The best fix for the mutex issue was to remove the scanning code, but it turns out some of the newer SoCs have started to omit the tbi-phy node when SGMII is not being used. As such, these devices will now fail unless we add a tbi-phy node to the first mdio controller.
