Re: State of the MPC5200 PSC AC97 driver
All, Thanks for the input and comments. I am also having a look at the I2S driver. There were attempts some time ago and I found few pieces of code floating on net but couldn't find anything cleaned up. Did anyone tried to put the results of those attempts together? Cheers, m. ___ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev

I'm actually working on the I2S driver now and I'll probably have something to post about a month from now. This is funded development, so I'll actually have lots of time to spend on it when I get back from ELC. Nice, I'll most probably work on it quite soon as well. It would be good to coordinate efforts, will ping you when I am about to start. Cheers, m. ___ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev

Re: [PATCH] [POWERPC] Update TQM5200, CM5200 and Motion-PRO _defconfig and .dts files
Olof Johansson wrote: ... I disagree, I have one defconfig for all our boards to date. It means I only have one kernel to build to test on all boards, instead of having to build a number of different kernels. Keeping it fairly generic also means a customer can start out using the generic kernel in case they want to, and later on add their own drivers and prune out what is not needed. Well, I just prefer separate defconfigs but I can live with the common one as well, feel free to merge it as you see it fit.

Re: [PATCH v4 02/13] [POWERPC] Add 'fsl, lpb' bus type for MPC5200 LocalPlus Bus

That doesn't matter for defconfigs. That needs to be done when you're tailoring a product regardless. defconfigs are simply a known good configuration; they are not intended to be the deployed config. If the defconfig enables all features used by any of the boards then it should be okay. That's true, defconfigs are only reference configurations, but still, I would opt for a separate defconfigs as it is more clear which target given defconfig is meant for and it is more convenient for development and customer to have it separate. And IMHO it's actually easier to maintain, as you don't need to consider all three boards each time you update defconfig and don't need to test each defconfig change on three (right now) boards, etc. Best Regards, m. ___ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev

[PATCH v5 04/13] [POWERPC] Add generic support for simple MPC5200 based boards
This patch adds support for 'mpc5200-simple-platform' compatible
boards which do not need a platform specific setup. Such boards
are supported assuming the following:
- GPIO pins are configured by the firmware,
- CDM configuration (clocking) is setup correctly by firmware,
- if the 'fsl,has-wdt' property is present in one of the
gpt nodes, then it is safe to use such gpt to reset the board,
- PCI is supported if enabled in the kernel configuration
and if there is a PCI bus node defined in the device tree.

This is a updated version of the patch 04/13 from the patchset that
adds arch/powerpc support for three MPC5200 based boards:
TQ-Components TQM5200, Schindler CM5200 and Promess Motion-PRO.
Supported boards table was made static __initdata and
sorted alphabetically.

Make that static.
Board table is no longer needed after kernel is initialized, it would
be nice to declare it static and __initdata, but that would be quite
ugly as it's a table of pointers and each string would require
separate statement too. If we don't do it then what's the benefit of
making it static?

I know you said this is still needed, but the driver really needs to
be fixed. This is not a proper way of using the device tree for
logical numbering.
True, driver needs fixing, but there are also other boards that use
that driver, and I am not able to test them right now. And, as I
recall Grant mentioned that he's working on straightening this up.

Is there actually any difference in behaviour betweeen the two LEDs?
If not, they should probably have the same compatible value, and
perhaps a label property or some such to associate them with a
particular LED.
In fact they are identical, so I have used the same compatible

From your description, this is an incorrect usage of cell-index - it
should *only* be used to index into SoC shared registers; never for
logical numbering.
Again true, but the situation is similar to the one with the serial
node.

Are you serious about this? Reading this from someone with your experience with device trees if feeding my worst fears... I think I better clarify. Once a device tree is written and shipped on a deployed board, it may never change again. Or, the kernel version may be updated more frequently than the device tree. Say, for example, that in kernel 2.6.25 tqm5200 and cm5200 are both handled by the same platform code. And lets say that in 2.6.26 we decide that they really need to have separate platform code (perhaps due to a firmware bug that needs to be worked around on one board). In this case, mpc5200-simple-platform has suddenly become useless. Or, does mpc5200-simple-platform now describe the cm5200 or the tqm5200? (an assumption which cannot be made due to deployed boards of both types claiming mpc5200-simple-platform). Trying to claim compatible at the board level is far more difficult than claiming it at the device level. Segher suggested on IRC: for boards it is pretty much useless most of the time, i think -- use model instead I can imagine that we may get into various trouble (or at least the situation is less flexible) if we are unable to update .dts file along with the kernel image on a deployed board. If so, then in fact there is little sens in using mpc5200-simple-platform compatible. But how serious is that, does such situation frequently happen in field? If we are able to update kernel image than what prevents .dts file update? Cheers, m. ___ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev

We generally don't leave a blank line between a function an its
EXPORT_SYMBOL().
Will fix that.
Also, any reason not to use EXPORT_SYMBOL_GPL?
No, no particular reason, I used EXPORT_SYMBOL because it's used for
exporting symbols in this file. But that's good point, I'll switch to
EXPORT_SYMBOL_GPL and I guess it would be nice to convert other
EXPORT_SYMBOL to EXPORT_SYMBOL_GPL as well, but that would be a
separate patch.
Cheers,
m.

Ok, is this actually a suitable usage for cell-index? It should only

purposes.

Ditto w.r.t. cell-index.
Not used, removed.
port-number also looks bogus - the device tree should not generally
contain logical numbering information in this manner. How and what
uses the port-number property?
'port-number' is used by serial driver (mpc52xx_uart.c), if present it
assigns a device number (/dev/PSCport-number) for given serial port.
That allows to override default auto-numbering.

cell-index present for one spi, but not the other makes be even more
suspicious about it's applicability here...
These are two different SPIs, both are part of the SoC but first one
is dedicated SPI interface while the second one is PSC port in a SPI
mode. Driver for the second one (mpc52xx_psc_spi.c) is actually using
cell-index to get the PSC port number it's controlling.

Is lpb another one of these chipselect/offset configurable bus bridge

Yes, it is, so I have switched to 2-cell addressing. Please see the v3

[PATCH v3 04/13] [POWERPC] Add generic support for simple MPC5200 based boards
This patch adds support for 'mpc5200-simple-platform' compatible
boards which do not need a platform specific setup. Such boards
are supported assuming the following:
- GPIO pins are configured by the firmware,
- CDM configuration (clocking) is setup correctly by firmware,
- if the 'fsl,has-wdt' property is present in one of the
gpt nodes, then it is safe to use such gpt to reset the board,
- PCI is supported if enabled in the kernel configuration

Well, but that would not be really user friendly, I'd rather stick with some default config. Strictly speaking the device-tree is not the right place for flash partitioning information. We put it there because it's preferable to having hardcoded per-board flash layouts in the code itself. It only really works well, though, when there are strong conventions (shared with the firmware) about how to partition the flash. Where it's really up to the user to determine how they want to lay out their flash, putting things in the device tree isn't a really good idea. In principle, you are right, we should not be putting a user dependent configuration into .dts files. But on the other hand, bindings have been defined for flash-like devices and their partition layouts and physmap_of device driver is expecting to get this information from the blob. So, it is the place for it. But if we are not to put partition layouts into the default kernel .dts files then we should provide/maintain some examples an that may be a even bigger mess. Incidentally, it's not required that *all* the flash address space be in partitions, so it is possible only give partitions for those flash chunks which the firmware needs to know about. That might be nicer solution but different variants of TQM5200 boards do not share the same subset of partitions (default u-boot partitions at least), so it will not help much.

I thought it was consensus to keep the new bus ids only in platform
code and not add them to the default list, and just pass that list in
to of_platform_bus_probe().
Sounds reasonable, will move it to the 5xxx platform code.

This MTD layout only works on boards with 32 MiB (or 64 MiB) flash
memory. On TQM5200 boards with smaller Flashes (16 MiB, 8 MiB and 4 MiB)
the MTD partition borders do not match with the physikal memory borders.
If there is a variant board with a different configuration, then the
device tree needs to be changed for that variant board; either by
having multiple .dts files in arch/powerpc/boot/dts or by having the
bootloader populate the correct information. A dtb as passed to the
kernel must exactly represent the hardware.
That also means that there is going to be a different flash map for
each possible flash size configuration.
Agree, that's one particular configuration (I guess I should add
proper comment), that should be updated if needed. But I'am not sure
if we should have multiple .dts files if it's only flash layout that
changes.
On a board with 16 MiB FLASH for example the big-fs _and_ the misc
partition could not be used. big-fs, because the memory is too small
(which is OK) and misc, because it overlaps 1 MiB over the physikal
flash border. So only the first 9 MiB of the flash could be used in Linux.
The remaining 7 MiB couldn't be accessed.
Perhaps it would be better to drop the flash layout from the in-kernel
dts files entirely since flash layout can be a fluid thing.
Well, but that would not be really user friendly, I'd rather stick
with some default config.

Please use of-platform-bus bindings instead. Let the of-platform bus
take care of scanning the tree for you. Don't do it manually.
Hm, let me try that instead, thanks for the suggestion.

First, this is the old flash binding, please use the new one.
Ok.
Second, is the flash really part of the SoC?
Not directly, it is attached to LocalPlus Bus Controller, which is
part of the SoC. And the soc@ is currently the only recognized of bus
for mpc5200, so if we want to move it to some other place new bindings
will need to be defined for lpc (LocalPlus Controller) bus. But I am
not quite sure where this should be attached. Bus is under LPC which
is a part of the SoC, but on the other hand Soc address range covers
only device control registers not the address space LPC may handle
(that may be varied). Any ideas?
The bus bridge has to be there. Is this something similar to the
localbus / chipselect bus controllers that a whole bunch of the
Freescale SoCs have?
Yes, that's kind of a local bus.
Because the bridged addresses don't lie in the
IMMR, althoug the control registers do, the current convention is to
make the localbus node a sibling of /soc, even though it is really
part of the SoC (/soc would perhaps be better called /immr, but /soc
is established now). This approach is imperfect, but so are most of
the other compromises we could make.
Incidentally LPC is a pretty bad abbreviation, since LPC more
frequently refers to the Low Pin Count connections that frequently
appear on south bridges or superIO chips.
How about 'LocalPlus Bus' and 'lpb' node then?

I think we're moving to the convetion of naming these nodes
soc@addr now. (You can drop the 5200 for the node name)
Seems that this will not be painless, U-boot uses hardcoded
paths with 'soc5200', so the appropriate patch will be needed.
That may be ok for new boards but what do we do with lite5200,
where U-boot upgrade is not always an option?

Both this patch and the CM5200 support patch (#6 in your series) are
pretty much clones of lite5200.c. I don't think this is the right
approach. Don't duplicate code in this way. Determine the common
bits and put them in a common place to be usable by any 5200 board
port.
It might even be better just to add a platform that matches on
compatible='mpc5200-generic' which is usable for mpc5200 boards that
don't need any custom setup by the kernel at platform setup time.
(which will probably be most 5200 boards).
Agree, will try more generic approach.

Are you *sure* you want this? You should only be touching port_config
if firmware fails to set it up correctly. Don't blindly copy what was
done for the lite5200.
Lite5200 touches it because firmware does *not* do the right thing at
the moment.
Yes, that's needed, but will be moved to U-boot.

Freescale? Really?
Well, not really...
Something like
seq_printf(m, Vendor\t\t: TQ Components\n);
seq_printf(m, Machine\t\t: %s\n, model);
and model set to 'tqc,tqm5200' would be more accurate but going for
compatible='mpc5200-generic' platform we may need to drop Vendor line
anyway.

Get rid of this.
Agree, that may be overhead in some cases. But there would be also
cases where printing out a machine name would be informative. CM5200
is one such example, there are several variants of the hw and platform
name is too generic.
Other situation would be adding compatible='mpc5200-generic' platform
where platform name would not provide any details.

First, this is the old flash binding, please use the new one.
Ok.
Second, is the flash really part of the SoC?
Not directly, it is attached to LocalPlus Bus Controller, which is
part of the SoC. And the soc@ is currently the only recognized of bus
for mpc5200, so if we want to move it to some other place new bindings
will need to be defined for lpc (LocalPlus Controller) bus. But I am
not quite sure where this should be attached. Bus is under LPC which
is a part of the SoC, but on the other hand Soc address range covers
only device control registers not the address space LPC may handle
(that may be varied). Any ideas?
