* [PATCH 2/2] powerpc/85xx: add Fman MDIO muxing support to the P4080DS
From: Timur Tabi @ 2012-08-10 22:31 UTC (permalink / raw)
To: Andy Fleming, Scott Wood, Kumar Gala, ddaney.cavm, linuxppc-dev,
netdev
In-Reply-To: <1344637896-14267-1-git-send-email-timur@freescale.com>
The Freescale P4080 SOC contains two Fman Ethernet controllers, each of
which contains four 1G Ethernet MACs and one 10G Ethernet MAC. The
SerDes protocol determines how the MACs are routed to various RGMII,
SGMII, or XGMII PHYs on the board, so the P4080DS reference board
provides a MDIO bus multiplexing feature that is controlled via GPIOs.
This patch adds the basic Ethernet, MDIO, mdio-mux, and PHY nodes
necessary to get MDIO bus muxing working, using Cavium's mdio-mux-gpio
driver. The remaining DPAA nodes (Qman, Bman, etc), as well as the
DPAA device drivers, are not included.

PPC: Don't use hardcoded opcode for ePAPR hcall invocation

Sending to Alex even though this isn't KVM-specific since the commit it

FSL MPICs have TFRR too. I'm not sure that the lack of fsl,mpic is a
good indication that TFRR is being set (e.g. we have old device trees
for FSL chips with U-Boot that are labelled as ordinary openpics).

timerfreq is unsigned. It can never be < 0.

You need to support fsl,available-ranges since that's in an accepted
binding and people could have partitioned setups already using it.
You also have a mismatch between the property you check and the error
string.

Where do you distinguish an FSL timer from an openpic timer? I thought
openpic timers didn't support cascading.
Oh, and don't probe by device_type.

open-pic isn't a vendor (or software project that acts like a

Why not just put clock-frequency in the node, instead of describing
TFRR? I don't think U-Boot currently sets TFRR.

Remove device_type. Not only is it deprecated outside of real OF, it's
wrong -- this isn't an openpic, it's just a subset of it.

4-cell interrupt specifiers are specific to Freescale MPICs. This means
there's no way to describe the timer interrupt on a non-Freescale
openpic. Again, I suggest we not bother with this in the absence of an
actual need to support the timer on non-Freescale openpic in partitioned
scenarios. The existing openpic node is sufficient to describe the
hardware in the absence of partitioning. We could have an
"openpic-no-timer" property to indicate that we're describing it
separately, so that the absence of a timer node isn't ambiguous as to
whether it's an old tree or a partitioned scenario. An fsl,mpic
compatible would imply openpic-no-timer.
Note that I believe many of the non-Freescale openpic nodes are going to
be found on systems with real Open Firmware, so we can't go changing the
device tree for them.

He doesn't work here anymore. We'll take care of the breakage.

You might want to get Ben's input as to whether he actually wants to see
that "quick fix" applied.

How did my approach not handle this case? As I said, ge_imp3a platform
code needs to set fsl_pci_primary manually before PCI init runs.
Adding a node to the device tree is not the answer, since that will
break compatibility with old device trees.

Only until all boards are converted, and this is *not* different with
your approach.

We do so many searches over the full device tree during boot that this
is meaningless.
Do you have benchmarks to show that device tree iteration is a
significant contributor to boot time?
