to be tested together with the pmdomain changes that are targeted for the
next release.

+title: Renesas R-Car X5H Module Controller
+
+maintainers:
+  - Geert Uytterhoeven <geert+renesas@glider.be>
+
+description:
+  Each instance of the R-Car X5H Module Controller (MODULE CONTROL) provides
+  Power Gating for up to 64 Power Domains, and Module Standby and Reset for up
+  to 256 modules in the Power Domain of each Module hierarchy.

+
+  '#power-domain-cells':
+    description: |
+      - The first power domain specifier cell is the power domain part, and
+        must be either the Module Power Domain Gating (MPDG) register index
+        (0x00-0x3f) from the datasheet, for power domains which are backed by
+        MPDG bits and which can be controlled in that manner,  or a Power
+        Domain number, as defined in
+        <dt-bindings/power/renesas,r8a78000-mdlc.h>, for power domains which
+        are always on, and for which there are no MPDG bits to control them.
+
+      - The second power domain specifier cell is the module standby part, and
+        must be the module number (0x00-0xff), composed of the Module System
+        Reset (MSRES) register index in the high nibble, and the Module Reset
+        Destination bitfield index in the low nibble.
+    const: 2
+
+  '#reset-cells':
+    description:
+      The single reset specifier cell must be the module number (0x00-0xff),
+      and thus identical to the second power domain specifier cell.
