[cip-dev] [PATCH 4.4.y-cip 08/17] ARM: dts: r8a7744: Add SMP support

[Biju Das]

commit f1546da8a5c8862d1e66835affcfaf9a0c123abc upstream.

Add DT node for the Advanced Power Management Unit (APMU), add the
second CPU core, and use "renesas,apmu" as "enable-method".

Also add cpu1 phandle node to the PMU interrupt-affinity property.

Document SoC specific compatible strings for r8a7744. No driver change
is needed as the fallback strings will activate the right code.

[Biju Das]

commit b72ce26cb73afd042d65f737971f560a491e1275 upstream.

The iWave RZ/G1N board is almost identical to RZ/G1M. cmt and rwdt modules
are SoC specific and should be part of board dts rather than SoM dtsi. By
moving these nodes to the common dtsi it allows cmt and rwdt to be enabled
on both of these boards with less lines of code.

Does this mean this is working progress and voltages will be lowered
for lower frequencies as testing proceeds?

HI Pavel,

Thanks for the feedback.

It supports only DFS not DVFS(ie, by controlling CPUFREQ register you can control the CPU frequency.)

If it does not support voltage scaling, is the /* kHz - uV - OPPs
unknown yet */ comment up-to-date? Would something like /* hardware
does not support voltage scaling */ be more useful?

Best regards,

Yes true. As per the manual,  " Automatic transmission for PMIC control (DVFS) is not available because the RZ/G series products do not
support the DVFS function". 

So we need to fix this upstream first and later backport to cip kernel.

Biju

I checked this series, and I didn't see any problem.
I applied to linux-4.4y-cip branch.
