Hi all,
According to the Hardware User's Manual, automatic transmission for PMIC
control (DVFS) is not available on RZ/G1, R-Car E3, and RZ/G2E SoC.
Thanks to various experiments by Wolfram (thanks a lot!) and me, we
devised this really means that support for automatic DVFS is not
present, while the IIC automatic transmission feature itself is still
available, albeit not super useful.
Hence this patch series updates the renesas,iic DT bindings and DTS
files to always consider all variants and instances compatible with the
family-specific and generic versions, and converts the bindings to
json-schema.
Changes compared to v1[1][2]:
- Consider all variants and instances compatible with the
family-specific and generic versions.
I plan to queue patches 2-4 in renesas-devel for v5.15.
Thanks for your comments!
