[PATCH 0/4] tmio/sdhi: use max sd_buf size & clean header file before

[PATCH 0/4] tmio/sdhi: use max sd_buf size & clean header file before

[Wolfram Sang]

From: Wolfram Sang <wsa@the-dreams.de>

The main patch is patch 4 which uses the maximum sd_buf size, i.e. 32 bit on
Gen2 and 64 bit on Gen3. Instead of a new flag, we use the bus_shift
information we already have. See the patch description for details.

Before fixing this, I wanted to remove a magic value in that function which is
done in patch 3.

When adding the new define, I noticed that some description is missing in the
header which is fixed with patch 2.

When adding the description, I noticed this meanwhile obsolete define which
gets removed in patch 1.

That's the way it went :)

Tested on Salvator-X/M3-W and Lager/H2.

Regards,

   Wolfram

[PATCH 1/4] mmc: tmio: remove obsolete TMIO_BBS

[Wolfram Sang]

Since commit 10c7fcbd0f00a0 ("ARM: shmobile: sh7372: Remove ZBOOT
MMC/SDHI support"), this define is not needed anymore.

[PATCH 2/4] mmc: tmio: add references to bit defines in the header

[Wolfram Sang]

When defining bits, make sure we always have a reference to the register
they belong to. For now, renaming all bits properly seems too intrusive,
so at least make sure we have proper documentation.

[PATCH 4/4] mmc: sdhi: use maximum width for the sdbuf register

[Wolfram Sang]

We can derive the sd_buf width from the bus_shift parameter which tells
us how far registers are apart. Remove the obvious comment, too.

RE: [PATCH 4/4] mmc: sdhi: use maximum width for the sdbuf register

[Biju Das]

Hi,

I am having issues with this patch(commitid:-785b215250310c690142abb1bdbb0767b8487c49)
on iWave RZ/G1M board which is identical to R-Car M2.

Getting below SDHI1 errors during boot. The issue is fixed by reverting this patch.

RE: [PATCH 0/4] tmio/sdhi: use max sd_buf size & clean header file before

[Biju Das]

Hi,

I am having issues with this patch (commit id:-785b215250310c690142abb1bdbb0767b8487c49 " mmc: sdhi: use maximum width for the sdbuf register")
I am testing SDHI1 against linux-next-20170727 tag  with iWave RZ/G1M board which is identical to R-Car M2.

Getting below SDHI1 errors during boot. This issue is fixed by reverting this patch.

Uh, that's bad. Let's see, can you print out the bus_shift variable?

Like this

	pr_info("bus_width: %u\n", host->bus_shift);

before this line?

Thanks,

This should be '1'.

Which tree is this based on? I can't find SDHI nodes for r8a7743 in its
dtsi file in linux-next? I'd think the node is not correct.

It is not upstreamed yet. I am going to upstream this patches with in a week or two.
Currently this patch is under internal review.
It is identical to R-Car M2.I believe this issue should reproducible with R-Car M2-W board(r8a7791).

I first rebased my SDHI patches with renesas-dev branch and it worked fine.

Then I rebased the same patches on linux-next + relevant patches from renesas-dev , it is started showing the issue.
Then I found that this patch is causing the issue.

Please find the  DT related entries here.

Ok, I see the problem now. It is likely that we in deed need to revert
the patch because I missed that Gen2 has two versions of the SDHI
controller and the second version has an exception with the SDBUF
register.

Thanks for the report! (one suggestion for next time: please describe which
branch you tested)

Regards,
