Merge tag 'rtc-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux

Pull RTC updates from Alexandre Belloni:
 "The RZN1 driver got a fairly comprehensive cleanup. More DT binding
  are converted to DT schema, leaving only 5 remaining files to convert.

  Subsystem:
   - patchwork project is moving to kernel.org
   - fully initialize clk_init_data
   - add missing MODULE_DEVICE_TABLE()
   - DT bindings conversions to DT schema

  Drivers:
   - ds1307: fix WADA bit for alarms on RX8130
   - rzn1: add support for RZ/T2H and RZ/N2H, many fixes"

- Motorola mc146818 compatible RTC
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Required properties:
-  - compatible : "motorola,mc146818"
-  - reg : should contain registers location and length.
-
-Optional properties:
-  - interrupts : should contain interrupt.
-  - ctrl-reg : Contains the initial value of the control register also
-    called "Register B".
-  - freq-reg : Contains the initial value of the frequency register also
-    called "Register A".
-
-"Register A" and "B" are usually initialized by the firmware (BIOS for
-instance). If this is not done, it can be performed by the driver.
-
-ISA Example:
-
-	rtc@70 {
-	         compatible = "motorola,mc146818";
-	         interrupts = <8 3>;
-	         interrupt-parent = <&ioapic1>;
-	         ctrl-reg = <2>;
-	         freq-reg = <0x26>;
-	         reg = <1 0x70 2>;

-	- "ti,da830-rtc"  - for RTC IP used similar to that on DA8xx SoC family.
-	- "ti,am3352-rtc" - for RTC IP used similar to that on AM335x SoC family.
-			    This RTC IP has special WAKE-EN Register to enable
-			    Wakeup generation for event Alarm. It can also be
-			    used to control an external PMIC via the
-			    pmic_power_en pin.
-	- "ti,am4372-rtc" - for RTC IP used similar to that on AM437X SoC family.
-- reg: Address range of rtc register set
-- interrupts: rtc timer, alarm interrupts in order
-
-Optional properties:
-- system-power-controller: whether the rtc is controlling the system power
-  through pmic_power_en
-- clocks: Any internal or external clocks feeding in to rtc
-- clock-names: Corresponding names of the clocks
-- pinctrl-0: a phandle pointing to the pin settings for the device
-- pinctrl-names: should be "default"
-
-Optional subnodes:
-- generic pinctrl node
-
-Required pinctrl subnodes properties:
-- pins - Names of ext_wakeup pins to configure
-
-Optional pinctrl subnodes properties:
-- input-enable - Enables ext_wakeup

-- ti,backup-battery-chargeable: The Palmas series device like TPS65913 or
