[PATCH 0/8] ARM: renesas: Latest r8a774[35] dts updates

[Chris Paterson]

This series contains multiple additions to the r8a774[35] device trees.

I've bundled them into a series to help avoid merge issues due to multiple
changes to the same files. Hopefully this doesn't add too much confusion!


Kind regards, Chris

I think that should be "[PATCH v3] mmc: renesas_sdhi: Add r8a7743/5 support"

Hi,

with reference to "[PATCH v3 0/3] ARM: renesas: Enable SMP on R-Car E2"
is the CNTVOFF initialised in the boot loader of boards (in upstream)
for this SoC? If not I expect you will have trouble with the arch timer
on secondary CPU cores.

The patch itself looks good to me.

Exactly my question.

Fabrizio: Given your feedback on "[PATCH v3 0/3] ARM: renesas: Enable SMP on
R-Car E2", I think SMP enablement on RZ/G1E has to be postponed until "ARM:
shmobile: rcar-gen2: Make sure CNTVOFF is initialized on CA7/15" has been
accepted upstream.

I can confirm that this patch relies on:
* "ARM: Add definition for monitor mode", and
* "ARM: shmobile: rcar-gen2: Make sure CNTVOFF is initialized on CA7/15 "
as the bootloader doesn't initialize CNTVOFF.

You are right, somehow we missed the comment made by Simon on Monday:

" I would like to deffer the third and last patch until v4.16 to avoid
an awkward branch dependency on the above - the branches are different
even though the tree is the same. Please resubmit this patch once the
above dependencies are present in an rc release, which at this stage
I expect to be v4.15-rc1."

Apologies for this, we will send this patch later on, once both patches have been
accepted upstream.

Simon, is this going to make the application of the remaining patches problematic?
Please, let me (or Chris) know if you want us to rebase and resend without this
patch.

Best regards,
Fabrizio

we thought exactly the same thing, therefore we rebased and we re-ran our tests, to discover that something broke in between versions.
I'll be in touch once I have more information, but it's a no go for now.

Hello Geert, Simon,

the problems I am seeing are not related to APMU/SMP, I'll send a v2 shortly.

No wp-gpios property means this is a µSD slot, right?

Do you have any plans to enable sdr-50 and sdr-104?
Is it not supported for some reason?

I don't mind if its not enabled in this patch but I would like to
know if it can be enabled or not and reflect that information in the wiki.

Nope (unless the hardware changes down the line).
Both vmmc and vqmmc are fixed to 3V3 on the iWave-E SOM module.

I take that the absence of a wp-gpio means that that this is a µSD slot.
Could you help me by documenting this correctly on
http://elinux.org/index.php?title=Renesas-MMC-Enabled-Speeds ?

For some reason I thought that SDHI0 wasn't exposed at all, so I guess
my reading of the documentation was incorrect.


I think you also want sd-uhs-sdr50 here too.
You can test it by removing the sd-uhs-sdr104 property.

Whilst playing with uhs properties I have noticed that with the version of the DT I was using I couldn't put sdhi0 into an uhs mode and that was down to the fact that the driver wasn't driving the regulator to 1.8V. This happens because (in my case) the power regulator gets probed after the sdhi does, and the sdhi code doesn't seem to deal with it. Am I the only one with this problem or is it a known problem?

Thanks,
Fabrizio

RE: [PATCH 4/8] ARM: dts: iwg22d: Enable SDHI0 controller

[Fabrizio Castro]

Hello Simon, Geert

thank you for your patience on this one. We found out that there is an HW issue on SDHI0 , SDHC_CD# and SDHC_CMD (on the carrier board) are pulled up to 3.3V, therefore we are dropping UHS on this interface, and as result we are dropping this patch. We will send a V2 shortly.

Thanks,
Fabrizio

Thank you for doing this.
We are working on a new patch now, I'll submit a V2 as soon as it is ready.
Just to recap (all in one place), we found an HW issue and a SW one preventing SDHI0 from working properly at UHS SDR50 and SDR104, therefore we need a new patch to limit the speed of this interface.

Thanks,
Fabrizio

RE: [PATCH v2] ARM: dts: iwg22d: Enable SDHI0 controller

[Fabrizio Castro]

Hello Simon,

just to clarify the changes between v1 and v2, we can't use SDR50 and SDR104 (due to an HW issue) therefore the pinctrl for UHS has been removed and we dropped property "sd-uhs-sdr104". High Speed has been tested, therefore if you are happy with the patch I guess you can update the following page accordingly:
http://elinux.org/index.php?title=Renesas-MMC-Enabled-Speeds&type=revision&diff=451426&oldid=451421

Although (due to a bug) sdhi0 may not hold a reference to "vccq_sdhi0", the gpio regulator will initialize "SDHI0 VccQ" at 3.3V.
I have sent another patch (mmc: tmio: check mmc_regulator_get_supply return value) to start a discussion about a possible fix for the bug.

Let me know if you need more information.

Thanks,
Fabrizio

Thanks again for following up on this.

I have applied the patch with Geert's tag.

I have also updated the Wiki at the URL above,
feel free to make any further updates there as appropriate.

Does the device have partitions?

We aren't confident that all devices will come with the same partitions, so decided not to add any here.
