[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

WBR, Sergei

[PATCH 1/2] ARM: shmobile: henninger: initial device tree

[Sergei Shtylyov]

Add the initial device tree for the R8A7791 SoC based Henninger board. SCIF0
serial port support is included, so that the serial console can work.

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.

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

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.

    I can't, there will be no console at all.

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?

Seems like we can use some consistency:

    Yes, it is all uppercase. See e.g. http://www.elinux.org/R-Car/Boards/SILK.

Agree we could use some consistency but before we start cooking up names
do we expect this to have any effect on compatibility for users?

    Don't think so, I would have seen at least some garbage on the console.
There was nothing. I'm still not sure what the problem was...

    Possible with the new board.

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

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.

Thanks Sergei,

I have queued this and the following patch up for v4.4.

[PATCH] ARM: shmobile: fix SILK board name

[Sergei Shtylyov]

Unfortunately, the SILK board bindings were not quite correct, as the  board
name should be all caps.  Fix that,  adding the board model #  in parens and
removing stray semicolon.

Thanks, I have queued this up.

[PATCH] ARM: shmobile: porter: add Ether DT support

[Sergei Shtylyov]

Define  the Porter board dependent part of  the Ether device node.
Enable DHCP and NFS root for the kernel booting.

This  patch  is analogous to the commit 26b0d2cf73cb (ARM: shmobile: henninger:
add Ether DT support)  as there  are no differences between those boards in this
respect.
