True for simple-bus.

However, the combination of "simple-mfd" and "syscon"
seems a well established strategy when
registers are mixed/interleaved in a syscon block.

(For example, chip-control@ea0000 node of
arch/arm/boot/dts/berlin2.dtsi)

socionext,uniphier-{pxs2,ld20}-thermal is an SoC-specific compatible string.
The internal-offset is included
in the HW-spec associated with the compatible.
I believe 'socionext,reg_offset' is pointless.
