[PATCH v3 00/16] mmc: tmio: another batch of TMIO MMC fixes and cleanups

[Masahiro Yamada]

In the previous batch (https://lkml.org/lkml/2017/11/24/428)

14 patches were applied, the rest is under discussion.

This series consists of 16 patches.

Patch 1-4:  repost from v2.

Patch 5-11: new patches  (cleanups of WP flag)

Patch 12: updated per Wolfram

Patch 13: repost  (almost reviewed)

Patch 14: updated

Patch 15: new

Patch 16: repost (almost reviewed)

[PATCH v3 11/16] mmc: tmio: deprecate "toshiba,mmc-wrprotect-disable" DT property

[Masahiro Yamada]

This property is equivalent to "disable-wp" defined in
Documentation/devicetree/bindings/mmc/tmio_mmc.txt

The TMIO MMC core calls mmc_of_parse(), and it sets
MMC_CAP2_NO_WRITE_PROTECT if "disable-wp" property is present.

We do not need a vendor-specific property to do the same thing.

Let's remove the description from the dt-binding to prevent new boards
from using it.

I am keeping the driver code for existing DT files, but added
comments that this is deprecated.

This is mistake.

"disable-wp" is defined in

I picked patch5 and patch6, as those seemed trivial. Unless there is a
rc9, let's aim for 4.17 for the rest.

I can't find the branch where you picked these patches? I wanted to use
it to apply the rest of the patches. They don't seem to fit on v4.15
or current linus/master. Can you share this branch?

I will do reviewing now "visually". But please wait until I tested them
before applying.

Thanks,

You need to check again. :-)

Patches up and to patch6 is already in Linus' tree v.16rc1, those I
carried for quite a while on my next branch before sending them in the
PR to Linus.

I am eager to apply those patches you already have reviewed (to
patch14), as those mostly seemed rather trivial and should be nice
cleanups.

Do you mind me going ahead, then you can continue and review/test the rest?

Yes, we can work incremently from there. I'll send patches if I discover
something unexpected.

this one which needs a fix. I will send it as an incremental patch.

Yamada-san, Wolfram,

I have added Wolframs tags to the already applied patches and applied
that last two, 15 and 16.

They are all present in my next branch. The fix that Wolfram sent on
top, is added immediately after the commit it fixes.

Kind regards
Uffe

Thanks. Please note that patch 14 misses my Rev tag. (I gave it
yesterday but the patch was accidently applied before. One round too
early, so to say).

Could we also squash it, then?

If Wolfram is fine with squashing,
that would be cleaner.

In that case, can you add Tested-by
to patch 12?

BTW, the subject of the applied version is wrong.

In my original post:
https://patchwork.kernel.org/patch/10170007/
"toshiba,mmc-wrprotect-disable"
No space after the vendor prefix.


But, applied commit (788778b0d21a6d5cd5)
I see a space, like
"toshiba, mmc-wrprotect-disable"


I think this is a bug of patchwork.


I have seen various bugs that break
the patch format.

I filed some bug reports for patchwork,
but not sure what happened.
