[PATCH 0/4] Add Ether DT support for R8A7778/BOCK-W reference board

[PATCH 0/4] Add Ether DT support for R8A7778/BOCK-W reference board

[Sergei Shtylyov]

Hello.

   Here's the set of 4 patches against Simon Horman's 'renesas.git' repo,
'renesas-devel-20130830' tag. Here we add the Ether device tree support working
on the R8A7778/BOCK-W reference board. The patchset requires the 'sh_eth' driver
device tree support posted earlier in order to work.

[1/4] ARM: shmobile: r8a7778: add Ether DT support
[2/4] ARM: shmobile: r8a7778: add Ether clock for DT case
[3/4] ARM: shmobile: bockw-reference: add Ether DT support
[4/4] ARM: shmobile: BOCK-W reference: add Ether PFC settings

WBR, Sergei

Documentation/devicetree/bindings/net/sh_eth.txt from "[PATCH 2/2] sh_eth: add 
device tree support" doesn't document this property, should you update it ?

    It's a standard property but completely optional for non-OF systems. I've 
not seen anybody document it but I should grep for it...

Documentation/devicetree/booting-without-of.txt mentions it, as well as a 
couple of other DT bindings document, but there's no clear documentation of 
what device_type should be for network device, and whether the property is 
mandatory or optional. Clarifying the documentation would be great.

It's documented in the ePAPR spec:

"The device_type property was used in IEEE 1275 to describe the device?s
FCode programming model. Because ePAPR does not have FCode, new use of
the property is deprecated, and it should be included only on cpu and
memory nodes for compatibility with IEEE 1275?derived device trees."

The bottom line is - don't use it, unless you've good good reasons?

Hi Sergei,

Thanks for your patch. What's the reason behind the r8a7778 SoC using
a compatible string for r8a7779 like "renesas,ether-r8a7779"?

It seems that you assume that the r8a7778 ethernet controller is 100%
compatible with r8a7779. Is that really true? For earlier versions the
sh_eth hardware documentation was anything but accurate, so it seems
to me that it must be more safe that r8a7778 would be using
"renesas,ether-r8a7778". What do you think?

Thanks,

/ magnus

    R8A7779 support has appeared first in Linux and as R8A7778 Ether is 
identical to R8A7779 and no wildcards are allowed in the device tree, I 
decided to use this "compatible" prop.

    I think R8A7778 and R8A7779 EtherMACs are identical. I've cross checked 
the documentation at the start of the development and the registers appeared 
to be the same.

But even if the current version of the documentation happens to be
similar in it still doesn't guarantee that the IP is the same. And
using the "correct" SoC compatible value doesn't really hurt in any
way, does it?

My feeling is that using the identical SoC as compatible value must be
the best option - unless we know for sure they are identical that is.

So unless we're 100% certain about IP compatibility I'm trying to
enforce that we either use a strict matching for exactly the same SoC
version or IP block. Using a different maybe-compatible SoC string
seems to be begging for future trouble IMO.

Laurent, any opinion?

I agree. If we had access to IP version information we could use that to 
construct the compatible name. As we don't, the SoC name is the best option, 
and to ensure future compatibility we should use the exact SoC version.

Using the SoC name is in keeping with recent discussions that
we have had about compat string names for shmobile. So I agree
with both Magnus and Laurent here (no surprise!).
