[PATCH] MAINTAINERS: add section MIPS BAIKAL-T1 SOC DRIVERS

[PATCH] MAINTAINERS: add section MIPS BAIKAL-T1 SOC DRIVERS

[Lukas Bulwahn]

In recent years, a number of drivers for the MIPS Baikal-T1 SoC have been
added to the kernel tree, but there is no dedicated MAINTAINERS section for
this SoC.

As all of the code has been contributed by Serge Semin, let us assume he is
still the active maintainer for this code rather than marking it orphan.

Add a new section MIPS BAIKAL-T1 SOC DRIVERS in MAINTAINERS.

Thanks for submitting this patch. I was going to send a similar change
in the framework of the arch-series which is hanging up in my local
repo and alas is still under construction. I know I shouldn't have
been waiting (I'm sorry about that), but I didn't expect the entire
work would have taken so much time. On a way to finishing it up I had
to switch my efforts to the EDAC and network drivers and got sucked by
the amount of work there. But I will definitely submit the Baikal-T1
SoC arch patchset when my work on another area is finally over.

Here are several comments about this patch. (Please see my last
comment should you be ok with accepting the patches with already fixed
notes.)

It's better to change the email to
+M:	Serge Semin <fancer.lancer@gmail.com>
I quicker respond from my private inbox, than from the corporate one.
This will also be useful should the corporate email eventually change.

I'd prefer this and these -+ being in a separate entry (see the
attached patches), because | the respective device IP-cores have been
re-used in another SoC. So | eventually the entries will be updated to
reflect that.              +---------------------------------+

This is already marked as maintained by me in the framework of the
generic DW APB SSI driver (See the "SYNOPSYS DESIGNWARE APB SSI
DRIVER" entry in the MAINTAINERS file).

Anyway in order to save your time from editing this patch. I've
prepared a series which takes into account all the comments above. If
you are ok with it, I can submit it for review. What do you think?

Add myself as a maintainer of the MIPS Baikal-T1 platform-specific
drivers. The arch-code hasn't been submitted yet, but will be soon enough.
Until then it's better to have the already available drivers marked as
maintained.

Sure, go ahead and submit your series. I just wanted to have all files
in ./drivers/bus/ have a proper maintainer and then got to look at the
BAIKAL T1 files.
