Re: [PATCH v2] staging: mt7621-dma: Add braces around else branches

2018-10-24 Thread Matthias Brugger
Hi Kiberly,

Thanks for adding all the emails in CC.
I would encourage you for your next patch to distinguish between CC and TO.
You should send your patch TO important maintainers in the get_maintainers.pl
list (as default, to all of them). If there is someone you really want to look
into the patch, then add him/her in TO as well.

Put the rest (people and mailing lists) in CC. Why? Some people filter their
mails so that they can concentrate on the mails they got send directly and look
on mails they are in CC with lower priority (maybe not at all, because there are
too much?). So it is important to have the maintainers in the TO list and not 
in CC.

Keep up the good work :)
Matthias

Apart from fixing styling issues it would be usefull to see if we can add
support for mt7621 to drivers/spi/spi-mt65xx.c

Not sure if that is something you want to work on :)

Thanks for the info. Do you know the status of the rest of the drivers in

Hm but shouldn't style issues be a criteria for not accepting a move out of
staging? I think so. You could add Armandos patch in your series or rebase your
series against Greg's tree, once he took the clean-up. Normally Greg is
incredibly fast :)

That's a good question. I think it's an accident as I don't have good knowledge
of the MIPS architecture. Also I try to track the upstream support for MIPS as 
well:

This driver has as compatible "arm,gic-v3-its". I wonder if this is

[PATCH 4/6] staging: fsl-mc: Use platform_msi_* infrastructure

2016-04-13 Thread Matthias Brugger
From: Matthias Brugger 

The fsl-mc driver can't be build as a module because it uses msi_*
functions directly. Port the driver to use the platform_msi_*
infrastructure instead, to allow it to be build as a module.

staging: fsl-mc: Convert to use platform_msi infrastrucutre

2016-04-13 Thread Matthias Brugger
Freescale MC driver can't be build as module as it uses it's own
msi implementation. This patch set converts the driver to use platform_msi
infrastructure instead, so that we can build the driver as a module.

Apart from that we have to export some functions of the msi framework to
handle the domain.

What? We are already creating a platform MSI domain for the ITS. How is
that going to work? If you want to convert this set of drivers to
platform ITS, fine. But you can't randomly hack in the ITS code and pray
for things not to fall apart.



From what I see, the difference between irq-gic-v3-its-fsl-mc-msi and 
the irq-gic-v3-its-platform-msi is the way ITS specific DeviceID is 
created in msi_prepare.


German, is there a reason why you use the ICID read from the DPRC as dev_id?

Matthias

[PATCH] staging: fsl-mc: bus: Drop warning

2016-04-14 Thread Matthias Brugger
When updating the irq_chip and msi_domain_ops, the code checkes for
already present functions.
When more then one ITS controller are present in the system,
irq_chip and msi_domain_ops got already set and a warning is invoked.

This patch deletes the warning, as the funtions are just already set to
the needed callbacks.

How can this situation happen?  And what do you mean by
multiple ITS controllers? ...multiple instances of the GIC ITS
on an SoC?



Yes, there are two arm,gic-v3-its defined in the FDT.

Is there any reason why apart from deleting "static" you move
fsl_mc_is_root to a different line?


I moved it just to keep internal consistency inside the source file where all 
the
static functions were grouped together in the first part of the file, and public
functions were in the second part.



Ok, thanks for clarification.
