The IP is shared by PPC and ARM, this renames it to qoriq for better
represention, and this also adds the CLK_OF_DECLARE support for being
initialized by of_clk_init() on ARM.

changes in v4:
 remove "corenet" literals omitted in v3 remove.

changes in v3:
 generate the patch with -M -C option

changes in v2:
 rename the driver name to ppc-qoriq.c for shared on PPC and ARM.

I think you need to also update drivers/cpufreq/Kconfig.powerpc
to use the renamed config option.

Is there binding documentation for these compatibles?

I guess that is an existing problem, and not related directly to this
patch? This patch is essentially just renames (though the V1.0/V2.0
stuff seems weird).

This patch is adding CLK_OF_DECLARE.

I'm fine taking this patch but your comments are still unresolved. What
do you think needs to be done to fix the problems that you see?

CLK_OF_DECLARE is totally worked on PPC. I will do it in a separate patch.
Regarding V1.0 and V2.0, it is not wired just same for now. But we are not sure if it is same for v3.0 in the future.

Besides updating drivers/cpufreq/Kconfig.powerpc, there is one more thing I am not comfortable with:
This patch uses " fixed-clock" as sysclk's compatible string, while on PPC we treated it as " fsl,qoriq-sysclk-[1-2].0".
That's inconsistent on both ARM and PPC platforms, neither did on bindings.

Thanks,
Yuantian

Thanks, I will update that selected config option of CLK_PPC_CORENET.

fsl,qoriq-sysclk-XXX is the way it is because of compatibility with the
fixups in existing U-Boots.  It shouldn't be used as a model.

That said, I don't think you really mean "this patch", as it doesn't
contain the device tree updates, and "fixed-clock" does not appear.

"fixed-clock" will appear when ls102x platform DTS gets upstreamed eventually.
That would be fine if you don't think "fsl,qoriq-sysclk-xxx" having different meaning on ARM and PowerPC is a issue.
