Hmm, that was my interpretation of #15 in Documentation/SubmittingPatches... ;-) Maybe it should read
<snip>
Improve the recovery of the MPC5200B's I2C bus from errors like bus hangs. This includes making the bus timeout configurable, a better detection of cases where the bus has to be "fixed" after a timeout, and a more thorough fixup sequence.
</snip>

Well, basically it was a rfc. I apparently need it on my 5200B board, but I hoped to get some more insight from the Freescale/I2C gurus (see "open questions" in the post). Thus merge window, IMHO...
Thanks, Albrecht.

Is the timeout really a /software/ property? My feeling is that the timeout basically depends upon the bus clock and the chips attached to the bus. Therefore, it is linked closer to the composition of the board's hardware as described in the device tree, than to any userland software. Or am I totally wrong here?
Thanks, Albrecht.

You mean dev->is_pcie?
Why isn't pci_scan_device calling pci_setup_device for you? That
should do the proper PCIe init depending on the device, along with
extracting other device info...

Might be also an idea to define it with ~0 (clock is still unsigned). If
possible, the code checking for those two cases (0 and "-1") should be close
together. That could be a compromise until more quirks are needed ;)

* [PATCH v2 0/3] i2c-mpc: add support for the Freescale MPC512x and other fixes
From: Wolfgang Grandegger @ 2010-01-25 20:55 UTC (permalink / raw)
To: Linux-i2c; +Cc: Devicetree-discuss, Linuxppc-dev, Wolfgang Grandegger
From: Wolfgang Grandegger <wg@denx.de>
This patch series adds support for the MPC512x from Freescale to the
i2c-mpc driver. At that occasion, issues with __devinit[data] have
been fixed and the doc of the FSL I2C dts bindings updated. It has
been tested on a MPC5121ADS, TQM5200 and TQM8560 board
Changes since v1:
- use macro MPC_I2C_CLOCK_PRESERVE/SAFE for the special clock settings.
- document the special DTS node "fsl,mpc5121-i2c-ctrl".
- update and correct the Kconfig help.
- some other minor fixes as suggested by Wolfram.

"__devinit[data]" has not yet been used for all initialization functions
and data. To avoid truncating lines, the struct mpc_i2c_match_data has
been renamed to mpc_i2c_data, which is even the better name.

* [PATCH v2 2/3] i2c-mpc: add support for the MPC512x processors from Freescale
From: Wolfgang Grandegger @ 2010-01-25 20:55 UTC (permalink / raw)
To: Linux-i2c; +Cc: Devicetree-discuss, Linuxppc-dev, Wolfgang Grandegger
In-Reply-To: <1264452906-32536-2-git-send-email-wg@grandegger.com>
From: Wolfgang Grandegger <wg@denx.de>
The "setclock" initialization functions have been renamed to "setup"
because I2C interrupts must be enabled for the MPC512x. This requires
to handle "fsl,preserve-clocking" in a slighly different way. Also,
the old settings are now reported calling dev_dbg(). For the MPC512x
the clock setup function of the MPC52xx can be re-used. Furthermore,
the Kconfig help has been updated and corrected.

* [PATCH v2 3/3] powerpc: doc/dts-bindings: update doc of FSL I2C bindings
From: Wolfgang Grandegger @ 2010-01-25 20:55 UTC (permalink / raw)
To: Linux-i2c; +Cc: Devicetree-discuss, Linuxppc-dev, Wolfgang Grandegger
In-Reply-To: <1264452906-32536-3-git-send-email-wg@grandegger.com>
From: Wolfgang Grandegger <wg@denx.de>
This patch adds the MPC5121 to the list of supported devices,
enhances the doc of the "clock-frequency" property and removes
the obsolete "cell-index" property from the example nodes.
Furthermore and example for the MPC5121 has been added.

Cc'ing Ben for PPC. Ben, should PPC use pci_scan_device when probing
its root busses? Sounds like it just uses pci_device_add for each one
it finds instead?
If you don't actually need scanning (though what about hotplug?) we can
move the call to device_add instead...

I need to give it more brain cells than I have available today :-) I'll
have a look tomorrow. In some case we build the PCI stuff up from the
firmware device-tree without actually doing any config space scanning,
so the root busses are treated a bit special.
Cheers,
Ben.

Oh, you mean you need to use the actual online count ? In which case,
yes, you do indeed need to be a bit more careful... In this case though,
you're probably better off special casing "3" :-)

Hi Breno,
I'm sorry for the regression. I didn't realize that PPC uses open-coded
PCI scan.
I guess the problem is caused by dev->pcie_cap, right? But I don't
understand what is happening clearly. Could you send me the detailed
information about the problem?

The set_pcie_port_type() needs to be called before pci_fixup_device() in
pci_setup_device() because fixup code might refer dev->pcie_cap. So I
don't think the first one is a good idea.

I think the second one is better. But to prevent similar problems, I
think it would be better to remove open-coded PCI scan in PPC in a
long term, though I don't know the background about that.

As I mentioned in the other e-mail, I think the set_pcie_port_type() needs
to be called before pci_fixup_device() call in the pci_setup_device()
because some fixup handler might refer the dev->is_pcie, dev->pcie_cap,
or dev->pcie_type.

I'm no huge fan of notifiers, but I suppose they have their place.
However ... I don't see a lot of win to making this optional. Just
inline the little two blocking_notifier_call_chain() calls directly,

Good, that's how it should have been done in the first place. :)
Of course, there's still the question of how to get driver-specific
configuration data into the driver...

Well, yes, it seems to be a border case.

I will add unregistration of the dma device. Unmapping and
freeing should be done automatically on driver detach, mapping
and allocation is done by devm_ioremap() and devm_kzalloc().

No problem, I set one up at:
git://git.pengutronix.de/git/wsa/linux-2.6.git
It is based on 2.6.33-rc5 and contains the newest patches for FEC and I2C. (I
will pick up the patches as they show up on the lists, so this tree will be
rebased!)
This tree includes all MPC5121-patches and the two USB-patches from Anton. I
haven't actually tested them yet, but they all applied cleanly, at least.
Testing will come soon...
Regards,
Wolfram
