* fsl_pq_mdio: Fix fsl_pq_mdio to work with modulesIonut Nicu2009-06-251-4/+4
| | | | | | | | | This patch fixes the case when ucc_geth or gianfar are compiled as modules. Without this patch the call to phy_connect() fails. Signed-off-by: Ionut Nicu <ionut.nicu@freescale.com> Acked-by: Andy Fleming <afleming@freescale.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* fsl_pq_mido: Set the first UCC as the mii management interface masterHaiying Wang2009-06-031-1/+5
| | | | | | | | | | | | | | Current code makes the UCC whose register range includes the current mdio register to be the MII managemnt interface master of the QE. If there is more than one mdio bus for QE, the UCC of the last mdio bus will be the MII management interface master which will make the primary mdio bus working unproperly, e.g. can not get the right clock. Normally the primary mdio bus is the first UEC's mdio bus. This patch allows the first UCC to be the MII management interface master of the multiple UCC mdio buses.

* net: fix fsl_pq_mdio driver to use module_init()Grant Likely2009-04-271-1/+1
| | | | | | | | | | | | | | | | | Modules are not supposed to use any of the *_initcall*() hooks as the entry point. fsl_pq_mdio.c was using subsys_initcall_sync() instead of module_init() to guarantee that the MDIO bus was initialized before the Ethernet driver goes looking for the phy. However, the recent OF helpers rework happens to also make sure PHY connection is deferred to .open time, so using an initcall is no longer necessary. This patch replaces the initcall with a more traditional an accepted module_init() call. Tested on Freescale MPC8349emitxgp eval board.

* fsl_pq_mdio: Revive UCC MDIO supportAnton Vorontsov2009-04-021-1/+1
| | | | | | | | | | | | | commit 1577ecef766650a57fceb171acee2b13cbfaf1d3 ("netdev: Merge UCC and gianfar MDIO bus drivers") introduced a regression so that UCC MDIO buses no longer work. This is because fsl_pq_mdio driver wrongly masks all non-TBI PHYs for !fsl,gianfar-mdio buses, while it should do that only for fsl,gianfar-tbi buses.

* fsl_pq_mdio: Revive Gianfar TBI PHY supportAnton Vorontsov2009-03-211-0/+1
| | | | | | | | | | | | | | | commit 1577ecef766650a57fceb171acee2b13cbfaf1d3 ("netdev: Merge UCC and gianfar MDIO bus drivers") broke the TSEC TBI PHY support: the driver now refuses to probe TBI MDIO buses as it doesn't know about "fsl,gianfar-tbi" compatible entry, and thus _probe() fails with -ENODEV status. Fix this by adding "fsl,gianfar-tbi" to the list of known Gianfar MDIO buses.
