This is also the case for R-Car Gen2?!?

                /* Special CPG clocks */
                cpg_clocks: cpg_clocks at e6150000 {
                        compatible = "renesas,r8a7791-cpg-clocks",
                        reg = <0 0xe6150000 0 0x1000>;

                mstp0_clks: mstp0_clks at e6150130 {
                        compatible = "renesas,r8a7791-mstp-clocks",
                        reg = <0 0xe6150130 0 4>, <0 0xe6150030 0 4>;

Or perhaps I am misunderstanding what you mean?

when I'm talking to journalists I just say "programmer" or something like that.
