[U-Boot] [PATCH 0/8] spi: Mark non-dm spi drivers as BROKEN

[U-Boot] [PATCH 0/8] spi: Mark non-dm spi drivers as BROKEN

[Jagan Teki]

We have trigger a zap patches about the legacy spi driver
which are not converted into dm, but the seems like most
of the associated developers are unaware about the migration
plan for SPI.

So, as per Tom request and make the removal smooth mark 
these non-dm drivers into BROKEN. The configs which enabled 
these drivers are now getting warnings saying that the resulting 
.config has broken config enabled and more over the code associated
with these configs will be removed in v2019.07 release.

Any inputs?
Jagan.

[U-Boot] [PATCH 1/8] Kconfig: Update CONFIG_BROKEN help text

[Jagan Teki]

Add bool text to describe what configurations is this for.

Update help text to describe the example use-case configs
which comes under CONFIG_BROKEN, they are
- legacy driver that would need dm conversion.
- legacy driver that doesn't have proper update since
  from the releases.

[U-Boot] [PATCH 3/8] Makefile: Trigger a warning for legcay spi drivers

[Jagan Teki]

We have a warning text for non dm converted spi drivers,
but the plan is to mark all these respetive drivers into
CONFIG_BROKEN.

So, trigger a warning saying that these driver configurations
and associated code will remove in v2019.07 (earlier plan is
to remove it from v2019.04)

Thanks for adding clarification. I suggest to rewrite it as:

This dependency is assigned to

- legacy drivers requiring driver model conversion
- legacy drivers lacking maintenance

But the code is not broken, it works fine, right ?

Yes the code work fine, but dm conversion not done yet. Now the
CONFIG_BROKEN can mark the driver configs which doesn't convert dm
yet, so the associated code will drop wrt MIGRATION deadline (similar
like what we showed on the Makefile before).

It is something like caution, before dropping it as suggested Tom.

That makes no sense, if the code works, it works and thus it is NOT
broken. Find some other way to flag it as non-DM-converted, not this hack.

np, It depends on whether we consider non-dm code(for legacy SPI
drivers) is broken or not, let Tom comment on this.

Again, the code works, it's not broken. That's very clear.
DM conversion is a separate matter, so let's not overload CONFIG_BROKEN
for such things. The Makefile warning seems sufficient to me.

The code is broken because it doesn't work with DM and is going to be
removed due to lack of maintenance soon.  My problem with this series,
but I need to check that we can do what I want to do and still keep
travis green, is have this (and the other non-converted and thus
non-maintained drivers) depend on, not select BROKEN.

The Makefile warnings tell people the code is going to be removed and
I'm trying to have the window be:
1) LOUD warning about needing work
2) 1 release past those loud deadlines of the code there, but not built
unless you enable BROKEN (as yes, I see code that's not updated to use
DM as being broken)
3) Code removed.

All that said, I continue to be open to delaying conversion / removal if
we're having:
- A discussion and proposed patches to do the conversion, but people
  need more time.  The work is in progress, but people need time as it's
  not as easy to convert as hoped for various reasons.
- A problem converting the driver to DM as it's highlighting some other
  problem within DM or hitting a size constraint or other problem.
- Someone who is willing to do the DM work is just now seeing this.
  Yes, this is possible especially since our LOUD Makefile warnings are
  also easy enough to miss if you're just automating the build and not
  doing it manually.

But I am not fine with:
- Code that isn't converted AND
- Code that no one seems to be converting AND
- Code that no one says they are going to convert AND
- The conversion deadline has past.

Seems there was some offer from Amarula to convert it , no ?

we can do some job on imx28 because we have a board there. I have asked

OK, good.  Can you and Marek please coordinate on:
- Updating MAINTAINERS files
- Dropping the boards that won't be supported moving forward (even if
  you can't mainline the custom board, there must be a ref platform you
  have/use, yes?).

And Michael, can you please subscribe to the u-boot-maintainers list?

Jagan, was there an old patch to try and convert this driver that may be
of help to Michael?  Thanks!

Might make sense to keep the MX28EVK, I'll ask about the other boards,
but I think they could be dropped.

I have asked previous version[1] author, Akash. He said he is going to
send the next version. He don't have hardware to test, but Michael or

Thank you for the change, as we've discussed earlier I won't have
objections against the driver removal when time is up.

Thus you can locally prepare a removal change in advance, the one
which you've sent earlier needs a minor update, please also remove
lpc32xx_ssp_init() function and its usage in the board files.

Yes, the idea here is to build the broken one by selecting BROKEN
so-that the travis-CI is green and have warning on the build,
otherwise it is another rework of selecting BROKEN for those
non-converted drivers if they depends.

ie what this series does.  Driver (for example) will select BROKEN,
that means it is still working bu would like to remove in next
versions and so..

What I'm after is
https://github.com/trini/u-boot/commits/WIP-BROKEN-test which is close,
but not quite there.  We no longer build the drivers marked as BROKEN by
default, and the fallout from that has been:
- Some missing dependencies (I'm trying to fix that now) leading to
  build problems.
- Needing to yank CONFIG_SPI for example from configs that had been
  using a now-not-built driver as the subsystem fails to link if there's
  no controller.  I don't think that's a problem however.
- Needing to migrate a few more symbols to Kconfig in order to be able
  to properly express "You need to depend on BROKEN to use this option
  now".

I still disagree with marking drivers that need DM conversion, but are
otherwise working perfectly fine, as broken. That's just misleading and
in fact incorrect. Invent some new, more descriptive Kconfig option please.

I also still disagree, but, fine, I'll add  CONFIG_DEPRECATED.

CONFIG_DM_NEED_MIGRATION or something ?

No, I think given the definition of deprecated:
"to withdraw official support for or discourage the use of (something,
such as a software product) in favor of a newer or better alternative"
(from https://www.merriam-webster.com/dictionary/deprecated) this is
good enough.
