[PATCH 0/2] Add R8A7791/Henninger board DT support

[PATCH 0/2] Add R8A7791/Henninger board DT support

[Sergei Shtylyov]

Hello.

   Here's the set of 2 patches against Simon Horman's 'renesas.git' repo,
'renesas-devel-v3.15-rc2-20140421' tag. Here we add support for the R8A7791-
based Henninger board AKA R-Car M2 Low Cost Development Platform (M2-LCDP);
this board is very like already supported Koelsch board, although some
differences do exist. The board can be booted using the device tree only, with
no pre-requisites...

[1/2] ARM: shmobile: Henninger: initial device tree
[2/2] ARM: shmobile: Henninger: add Ether DT support

Thanks, I have queued these up.

N.B: I do not currently have access to a Henninger board.
     So unlike other boards for ARM-based Renesas SoCs that are present in
     mainline I will not be boot-testing patches for this board.

Its not clear to me why that should be the case when you also have:

Is this a baud issue? If so is it possible to set uboot to 115200 bps?
This would be consistent with the way other boards are handled in mainline.

Its not clear to me why that should be the case when you also have:

		stdout-path = &scif2;

Is this a baud issue? If so is it possible to set uboot to 115200 bps?
This would be consistent with the way other boards are handled in mainline.

If it's not possible to update the bootloader, the other option is to
use the console parametuers in stdout-path, e.g.

	stdout-path = "serial0:38400n8";

That way all the console stuff should get set up as expected without a
command line being required. As far as I am aware, an explicit command
line should then override this if necessary.

Shouldn't that have a "Renesas" prefix or something like that?

It's unlikely that there will be another board called "SILK", but it
does make it hard for someone to get an idea of what the board is from
the model string alone.

    Oops, the patch was additionally against the Henninger->Porter rename

    Historically. no SH-Mobile .dts has used the vendor name in the "model" 
prop. I defer the decision to Simon but I think we should be at least consistent.

They are also my thoughts (except the bit about deferring to myself).

If there is a good motivation for a Renesas prefix then that is fine by me.
But in that case it seems that it would be appropriate to update
the existing renesas boards too.

The only thing that stood out to me about "SILK" was that unlike
other renesas boards names in .dtsi files it is all-capitals.
Its not a bit deal but as we are on the topic: is that intentional?

[PATCH v2] ARM: shmobile: silk: initial device tree

[Sergei Shtylyov]

Add the initial device tree for the R8A7794 SoC based SILK low cost board.
SCIF2 serial port support is included, so that the serial console can work.

Based on the original patch by Vladimir Barinov
<vladimir.barinov@cogentembedded.com>.

Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>

This patch is against the 'renesas-devel-20150211-v3.19' tag of Simon Horman's
'renesas.git' repo.  It requires just posted R8A7794 PFC DT  patch in order to
compile, and R8A7794 PFC driver patch in order for the pins  to be configured.

Changes in version 2:
- removed "console=" parameter from the kernel command line;
- added PFC node with SCIF2 pins subnode and referred it from the SCIF2 node;
- rebased the patch
- mentioned the origin of patch in the changelog.

[PATCH v2] ARM: shmobile: silk: initial device tree

[Sergei Shtylyov]

Add the initial device tree for the R8A7794 SoC based SILK low cost board.
SCIF2 serial port support is included, so that the serial console can work.

Based on the original patch by Vladimir Barinov
<vladimir.barinov@cogentembedded.com>.

Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>

---
This patch is against the 'renesas-devel-20150211-v3.19' tag of Simon Horman's
'renesas.git' repo.  It requires just posted R8A7794 PFC DT  patch in order to
compile, and R8A7794 PFC driver patch in order for the pins  to be configured.

Changes in version 2:
- removed "console=" parameter from the kernel command line;
- added PFC node with SCIF2 pins subnode and referred it from the SCIF2 node;
- rebased the patch
- mentioned the origin of patch in the changelog.

This patch is against the 'renesas-devel-20150728-v4.2-rc4' tag of Simon
Horman's 'renesas.git' repo.  It depends on just posted SILK board initial DT
patch in order to apply and on R8A7794 PFC DT patch posted yesterday in order
to compile.

[PATCH] DT: mmc: sh_mmcif: fix "compatible" property text

[Sergei Shtylyov]

The "compatible" property text contradicts even the example given in the MMCIF
binding document itself; moreover, the Renesas MMCIF driver only  matches  on
the generic "compatible" string, and doesn't look for at SoC specific strings
currently at all. Thus describe "renesas,sh-mmcif" string as mandatory and the
others as optional.

As you know, each SoC contains a wide range of on-chip devices and the
MMCIF device is just one of them. Exactly how to manage the DT
bindings must be up to each maintainer and of course this needs to be
aligned with the SoC maintainer and SoC vendor with policies used for
SoC support and BSPs and whatnot. Changing policy like this for a
single device without at least discussing this with the SoC
maintainers does not help.

For Renesas hardware we so far use both SoC part number and optionally
a generic binding as well. As commonly expected, the DT binding is
supposed to describe the hardware and if hardware devices are
compatible. Unless we use SoC part number in the compatible string
there is a risk that the SoC integrator simply copy-and-pastes generic
bindings "because it works" but this will result in DT binding based
on software compatibility and not hardware compatibility. Later when
the driver support is extended this may result in broken software due
to incorrect compatibility information through generic bindings.

If anything is unclear please ask and feel free to discuss this DT
topic with Simon, Laurent, Geert and/or me.

Thanks,

    I'm not changing the policy, I'm making the binding actually reflect the

    I didn't quite understand what you're proposing instead. Making SoC based 
strings mandatory? Changing the driver to look at the SoC based strings?

To clarify this, the current DT compatible strings policy for Renesas SoCs is 
to use a mandatory SoC-based string followed by a optional generic strings. 
Optional here refers to the fact that individual DT bindings can decide 
whether to use a generic string or not, based on hardware information. An IP 
core that has a different, incompatible implementation for each SoC it is 
present in can't make use of a generic compatible string. If a particular 
binding defines generic compatible strings those should be made mandatory by 
that binding.

In the MMCIF case, I would propose wording it as

- compatible: must contain one of the following
      - "renesas,mmcif-r8a7740" for the MMCIF found in r8a7740 SoCs
      - "renesas,mmcif-r8a7790" for the MMCIF found in r8a7790 SoCs
      - "renesas,mmcif-r8a7791" for the MMCIF found in r8a7791 SoCs
  followed by "renesas,sh-mmcif".

Adjusting the binding after driver implementation seems a bit reverse to me.

The way I see it, first you make a DT binding describing the hardware.
Then as second step, you make sure the device driver support the
hardware and the DT binding. As third or second parallel step you
integrate via a DT.

If you are concerned about the order of the compatible strings, unless
specified by the SoC vendor documentation it is in my opinion up to
each driver maintainer and/or developer to judge if the hardware is
compatible or not. So the development activity of determining if the
devices are compatible shall result in a correct compat string order.
I'm not so sure if it is required that this order is supposed to be
documented in the DT binding. Being more clear does not hurt though.

I think Laurent describes it pretty well. I'm not sure why you feel
that you need to change the driver though, so I wonder if there is
some misunderstanding going on here...

Please understand that all the compat strings included in the DT
binding document not necessarily have to be used by the driver. But
before merging DT integration code it seems customary that the DT
binding needs to be documented.

All "compatible" values should be documented before being used in a
.dts(i) file.

    Everything was done backwards with this binding: first, the driver

documented by Laurent.

[PATCH v2] DT: mmc: sh_mmcif: fix "compatible" property text

[Sergei Shtylyov]

The "compatible" property text contradicts even the example given in the MMCIF
binding document itself;  moreover, the Renesas MMCIF driver only matches on
the generic "compatible" string and doesn't look for the SoC specific strings
at all. Thus describe "renesas,sh-mmcif" as a fallback value.

Fixes: b4c27763d749 ("mmc: sh_mmcif: Document DT bindings")
Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>

---
The patch is against Ulf Hansson's 'mmc.git' repo's 'fixes' and 'next' branches.

Changes in version 2:
- kept the SoC specific "compatible" property values mandatory and made the
  generic string a fallback.

I don't believe this file is the appropriate place to describe
best-practice for the ordering of compatible strings which must surely be
documented elsewhere.

Perhaps it would be best to co-ordinate the R8A7793 and R8A7794
changes to avoid tedious conflicts.

    I thought about taking out Ulrich's binding patch and re-posting it along 
with this one but finally decided not to ruin his series. Do you mean that I 
should have posted his patch along with mine?

The document lists the acceptable compat strings for the driver.
Some are currently implemented by the driver. Some are not.
This provides a mechanism for enhancing the driver while maintaining
compatibility with existing DT blobs.

The document does not describe the way to order the compat strings, which I
believe is a more generic issue as many drivers have more and less specific
compat strings to describe hardware which is compatible with each other. To
some extent I believe it is up to the user, that is the person writing DT
files, to understand what the hardware they are dealing with is compatible
with. And to some extent I believe the ordering is a best-practice that
ought to be described in a high-level document if it is not already.

Your proposed update assumes that all past and future hardware handled by
current and future versions of the driver will be compatible with
"renesas,sh-mmcif". How can you possibly know that is true?

I mean we sould talk about this to come up with a plan that makes things
easy for the maintainer to pick up the compat strings for the R8A7793 and

Unfortunately, the SILK board bindings were not quite correct, as the  board

[PATCH v3] DT: mmc: sh_mmcif: fix "compatible" property text

[Sergei Shtylyov]

The "compatible" property text contradicts even the example given in the MMCIF
binding document itself;  moreover, the Renesas MMCIF driver only matches  on
the generic "compatible" string and doesn't look for the SoC specific strings
at all. Thus describe "renesas,sh-mmcif" as a fallback value.

Fixes: b4c27763d749 ("mmc: sh_mmcif: Document DT bindings")
Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>

---
The patch is against Ulf Hansson's 'mmc.git' repo's 'fixes' or 'next' branches.

Changes in version 3:
- reworded the "compatible" property description to look like the majority of
  the Renesas bindings.

Changes in version 2:
- kept the SoC specific "compatible" property values mandatory and made the
  generic string a fallback.
