Hi Simon,
The compatibility string 'renesas,r8a77965-thermal' is accepted but not
yet picked up, see '[PATCH v2 0/2] thermal: rcar_gen3_thermal: add
r8a77965 support'.
* Changes since v1
- Rebased to devel branch of Simons tree.
- Switch to R8A77965_PD_ALWAYS_ON instead of 32 in power-domains as the
constant is present in v4.17-rc1. This makes this patch depend on
'[PATCH] arm64: dts: renesas: r8a77965: use r8a77965-sysc binding
definitions' which adds the r8a77965-sysc.h include to the dtsi file.
