Hi Jacopo,

Thanks for the patch.

I haven't really looked at the rest of the patch yet - but the title stands out:

[PATCH 02/15] clk: renesas: cpg-msr: Add support for R-Car M3-N

Should this be s/cpg-msr/cpg-mssr/ ?

Regards

Kieran

Thanks for your patch!

Please refer to Table 8.2d of R-Car Series, 3rd Generation User's Manual:
Hardware (Rev. 0.80, Oct 31, 2017), so we know which exact version of
the datasheet
was used for the core clock definitions.

According to Figure 12A.1 the parent clock is S0D3. See also commit
6e7ddf89d67c2b0c ("clk: renesas: r8a7796: Correct parent clock of INTC-AP").

I don't care that much anymore.
It used to be a good idea when the bindings header went in separately,
as it was a dependency for both driver and DTS. But now we use hardcoded
constants in the first version of the DTS, so it doesn't matter anymore.
