Pull RTC updates from Alexandre Belloni:
 "There is an unusual amount of new drivers this cycle, and this
  explains the number of insertions.

  Other than that, the changes are the usual fixes and feature addition.

  Subsystem updates:
   - new quartz-load-femtofarads DT property for quartz load capacitance
   - remove rtc_class_ops.read_callback

  New drivers:
   - Abracon AB-RTCMC-32.768kHz-EOZ9
   - Amlogic Meson RTC
   - Cadence RTC IP
   - Microcrystal RV3028
   - Whwave sd3078

  Driver updates:
   - cmos: ignore bogus century byte
   - ds1307: rework rx8130 support
   - isl1208: add isl1209 support, nvmem support
   - rs5C372: report invalid time when the oscillator stopped
   - rx8581: add rx8571 support"

Cadence Real Time Clock
The Cadence RTC controller with date, time and alarm capabilities.
The alarm may wake the system from low-power state.
Required properties:
- compatible: Should be "cdns,rtc-r109v3"
- reg: Specifies base physical address and size of the register area.
- interrupts: A single interrupt specifier.
- clocks: Must contain two entries:
- pclk: APB registers clock
- ref_clk: reference 1Hz or 100Hz clock, depending on IP configuration
See ../clocks/clock-bindings.txt for details.
Example:
rtc0: rtc@fd080000 {
compatible = "cdns,rtc-r109v3";
reg = <0xfd080000 0x1000>;
clock-names = "pclk", "ref_clk";

Intersil ISL1209/19 I2C RTC/Alarm chip with event in
ISL12X9 have additional pins EVIN and #EVDET for tamper detection, while the
ISL1208 and ISL1218 do not. They are all use the same driver with the bindings
described here, with chip specific properties as noted.
Required properties supported by the device:
- "compatible": Should be one of the following:
- "isil,isl1208"
- "isil,isl1209"
- "isil,isl1218"
- "isil,isl1219"
- "reg": I2C bus address of the device
Optional properties:
- "interrupt-names": list which may contains "irq" and "evdet"
evdet applies to isl1209 and isl1219 only
- "interrupts": list of interrupts for "irq" and "evdet"
evdet applies to isl1209 and isl1219 only
- "isil,ev-evienb": Enable or disable internal pull on EVIN pin
Applies to isl1209 and isl1219 only
Possible values are 0 and 1
Value 0 enables internal pull-up on evin pin, 1 disables it.
Default will leave the non-volatile configuration of the pullup
as is.
Example isl1219 node with #IRQ pin connected to SoC gpio1 pin12 and #EVDET pin
connected to SoC gpio2 pin 24 and internal pull-up enabled in EVIN pin.
