Merge tag 'ib-mfd-clk-gpio-power-regulator-rtc-v6.20' into psy-next

Merge immutable branch between MFD, Clk, GPIO, Power, Regulator and RTC
due for the v6.20 merge window to apply further cleanups on top of the
BD72720 power-supply driver contained in this branch.

+description:
+  BD72720 is a single-chip power management IC for battery-powered portable
+  devices. The BD72720 integrates 10 bucks and 11 LDOs, and a 3000 mA
+  switching charger. The IC also includes a Coulomb counter, a real-time
+  clock (RTC), GPIOs and a 32.768 kHz clock gate.
+
+# In addition to the properties found from the charger node, the ROHM BD72720
+# uses properties from a static battery node. Please see the:
+# Documentation/devicetree/bindings/power/supply/battery.yaml
+#
+# Following properties are used
+# when present:
+#
+# charge-full-design-microamp-hours: Battry capacity in mAh
+# voltage-max-design-microvolt:      Maximum voltage
+# voltage-min-design-microvolt:      Minimum voltage system is still operating.
+# degrade-cycle-microamp-hours:      Capacity lost due to aging at each full
+#                                    charge cycle.
+# ocv-capacity-celsius:              Array of OCV table temperatures. 1/table.
+# ocv-capacity-table-<N>:            Table of OCV voltage/SOC pairs. Corresponds
+#                                    N.th temperature in ocv-capacity-celsius
+#
+# volt-drop-thresh-microvolt: Threshold for starting the VDR correction
+# volt-drop-soc:                Table of capacity values matching the
+#                                    values in VDR tables.
+#
+# volt-drop-temperatures-millicelsius: Temperatures corresponding to the volage
+# drop values given in volt-drop-[0-9]-microvolt
+#
+# volt-drop-[0-9]-microvolt: VDR table for a temperature specified in
+# volt-drop-temperatures-millicelsius
+#
+# VDR tables are (usually) determined for a specific battery by ROHM.
+# The battery node would then be referred from the charger node:
+#
+# monitored-battery = <&battery>;
