[PATCH v2] arm64: dts: r8a7795: salvator-x: Add current sense amplifiers

[Geert Uytterhoeven]

Add device nodes for two Maxim max961x current sense amplifiers
sensing the VDD_0.8V and DVFS_0.8V lines.

Based on a patch for r8a7796-salvator-x.dts by Jacopo Mondi.

Signed-off-by: Geert Uytterhoeven <geert+renesas at glider.be>

Bindings and driver are now in staging-next.

v2:
  - Use shunt-resistor-micro-ohms to match updated bindings.
