Thanks for your patch!

None of the DTBs are listed in arch/sh/boot/dts/Makefile, so how do you
build them without CONFIG_USE_BUILTIN_DTB/CONFIG_BUILTIN_DTB_SOURCE?

To make "make dtbs" and "make dtbs_check" work, I added:

     dtb-$(CONFIG_CPU_J2) += j2_mimas_v2.dtb
     dtb-$(CONFIG_CPU_SUBTYPE_SH7751R) += landisk.dtb
     dtb-$(CONFIG_CPU_SUBTYPE_SH7751R) += rts7751r2dplus.dtb
     dtb-$(CONFIG_CPU_SUBTYPE_SH7751R) += usl-5p.dtb

Having individual clock nodes (especially if they use the same register
block) is deprecated.  Please use a single node with compatible value
e.g. "renesas,sh7751r-cpg" and "#clock-cells = <1>", and let the driver
create all clocks itself.

label "scif" (serial@ffe00000 is "sci").

> +               compatible = "renesas,scif";

"renesas,scif-sh7751r", "renesas,scif" ?

Most-specific first, i.e.

    compatible = "iodata,julian", "renesas,sh7751-pci";

(and we do need DT binding documentation!)

However, "iodata,julian" is a too-generic name.

All SoC-specific parts should be extracted into sh7751r.dtsi, so it can be
shared by all board DTS files.
