Does 'select CLK_R9A06G032' automatically activate the dependencies
like 'CLK_RENESAS' too ?
Do you mean things like CLK_RCAR_CPG_LIB for example?
The new clock driver has no dependencies (except perhaps ARCH_RZN1).
Since this clock driver is essential to boot, I figured it was best to
select it in Kconfig, rather than require each board defconfig to
specify the same options.
If there is a better/preferred approach, I will implement it.

Should this be in mach-rmobile (which, maybe, should be renamed to
mach-renesas) ?
I vaguely recall that I discussed this with someone (possibly you),
likely on IRC. And I think the conclusion was there was a significant
enough difference (possibly Cortex-A7 versus A9?).
I don't have a strong preference, if moving to mach-rmobile makes sense,
let me know and I can give it a go.

Why not enable icache with icache_enable() too ?
The I-cache is enabled quite early in arch/arm/cpu/armv7/start.S
