[PATCH 00/11] Add R8A77980/Condor board support

[PATCH 00/11] Add R8A77980/Condor board support

[Sergei Shtylyov]

Hello!

Here's the set of 11 patches against Simon Horman's 'renesas.git' repo's
'renesas-devel-20180202-v4.15' tag. I'm adding the device tree support for
the R8A77980-based Condor board (note that NFS root would only work on the
Condor boards [re]wired for booting from EtherAVB -- we haven't been able
to get the 'sh_eth' driver working in either U-Boot or Linux so far).
The necessary SYS-DMAC, [H]SCIF, and EtherAVB bindings updates have been
posted yesterday, the clock driver was posted the day before...

[01/11] soc: renesas: identify R-Car V3H

[PATCH 05/11] arm64: dts: renesas: initial R8A77980 SoC device tree

[Sergei Shtylyov]

The initial R8A77980 SoC device tree including Cortex-A53 CPU, GIC, timer,
CPG, RST, and SYSC.

Based on the original (and large) patch by Vladimir Barinov.

I think you want to leave out the above #include, as it will go upstream
through a different path (you're already using hardcoded clock numbers,
assuming the same).

With the above fixed:

    I still need CPG_{CORE|MOD}.

Shouldn't this be 19 (S3D1) instead of 16 (S2D1)?

With that fixed (for all (H)SCIF ports);

   Seems like that... at least after out chat. :-)

   The manual tells me SCKi for the SCIF ports should be the same S3D1.

According to the Hardware User Manual 0.80, V3H does not have the Stream

This is different from H3, M3-W, and D3. Care to elaborate for the layman

   See Documentation/devicetree/bindings/net/ethernet.txt, I don't know anything beyond that anyway. :-)
   Based on the manual, I'd think we should use "rgmii" here and override it in the board DT if needed...
