9 siblings, 0 replies; 18+ messages in thread
From: Marek Vasut @ 2010-08-04 11:22 UTC (permalink / raw)
To: linux-arm-kernel
This huge patch mostly shuffles code. The spitz.c file contained terrible mess
and needed a cleanup, here it is:
1) Made every part modular, components are not built in if not selected.
2) Removed loads of preprocessor goo, mostly "#ifdef MACH_AKITA .... #endif" and
similar code. The kernel size will grow by a few kb now, but the file is much
more readable.
3) Reworked SD/CF power setting function and made it reentrant.
4) Add ISL6271A regulator support
5) Correctly register WM8750

NAK.
That's not what a large portion of this patch does. You have put all of
the pin definitions into balloon3_pin_config and negated the work that
was done to ensure that a single kernel could run on different variants
of the balloon3. If a feature isn't configured on the board you
shouldn't configure the MFPs for that feature.

I have only this one, but read on.

That's not true. You should configure them as inputs. The big plan (in another
patch) is to do this the same way colibri270 is done (balloon3 baseboard +
expansion boards).

A large portion of it removes setting the MFPs based on the board
capabilities. That's a different piece of work to making the various
components modular.

I suspect you have a similar board to me; a double sided board fairly
well populated (sound, CF, USB host + slave, LCD). The Lightwriter, for
example, is a single sided board using fewer peripherals. The CUED
variant I believe is different again for their needs.

I don't have a copy of the PXA reference to hand, so I'm happy to accept
best practise is to set unused pins to be inputs. However the changes in
this patch don't do this and may end up setting some pins that are used
for something else to an unexpected output.
I'm failing to understand the motivation for these changes, especially
if you have a plan to later do more appropriate cleanup.

The changes in this patch should not screw up anything. If they do break
something, it'll be eventually found out. Do you have any trouble with this
patch on your board?

Because you can't do everything at once. I prepared the ground for further
changes.
I wonder why noone actually sent a better patch ever since balloon3 was pushed
mainline ... that's like 15 kernel versions already, isn't it? I also believe
this patch will make it very hard to forward-port the out-of-the-tree patches on
balloon3 website, which are often in terrible shape ... well that's sad.

I'm trying to get the sane ones mainline, but otherwise I'm NOT INSANE to care
for out-of-the-tree patches :)

I'll happily agree it's far from perfect; what I've suggested as an
improvement is either a board configuration register which would
indicate the features on the board, or potentially the use of device
tree when/if that hits. Until that point what we've got, while a kludge,
does allow a single kernel to run on all board types.
(In Balloon's defence a lack of probability is hardly unique to that
platform.)

I don't envisage any problems with my board, which as I said is I
suspect identical to yours. Unfortunately I'm currently at DebConf and
so don't have any access to it to confirm. My worry is about the boards
I don't have but know exist.

Let me be clear about the bits of this patch I have a problem with; I'm
fully in favour of the bits that wrap up config in CONFIG_[FEATURE].
It's the removal of doing the pxa2xx_mfp_config based on the
balloon3_has feature bits that I think is mistaken.

The base balloon3 support patch didn't go in to Eric's devel tree until
September; 2.6.32 is the first release with it present.
With regards to the out of tree patches that haven't been pushed that's
largely due to a complete lack of time on my part; getting the base
support in took a lot longer than I expected and there have also been
VHDL changes I haven't had a chance to fully discuss with the author to
determine the effect on existing patches. It's great you've picked up
this work, but please don't think there's any lack of desire to get
things pushed upstream; it mostly comes down to a lack of manpower.
