new device support in terms of LoC, but there has been some cleanup
 in the core as well as the usual minor clk additions to various
 drivers.
 
 Core:
 
  - parent tracking has been simplified
 
  - CLK_IS_ROOT is now a no-op flag, cleaning up drivers has started
 
  - of_clk_init() doesn't consider disabled DT nodes anymore
 
  - clk_unregister() had an error path bug squashed
 
  - of_clk_get_parent_count() has been fixed to only return unsigned ints
 
  - HAVE_MACH_CLKDEV is removed now that the last arch user (ARM) is gone
 
 New Drivers:
 
  - NXP LPC18xx creg
 
  - QCOM IPQ4019 GCC
 
  - TI dm814x ADPLL
 
  - i.MX6QP
 
 Updates:
 
  - Cyngus audio clks found on Broadcom iProc devices
 
  - Non-critical fixes for BCM2385 PLLs
 
  - Samsung exynos5433 updates for clk id errors, HDMI support,
    suspend/resume simplifications
 
  - USB, CAN, LVDS, and FCP clks on shmobile devices
 
  - sunxi got support for more clks on new SoCs and went through a minor
    refactoring/rewrite to use a simpler factor clk construct
 
  - rockchip added some more clk ids and added suport for fraction dividers
 
  - QCOM GDSCs in msm8996
 
  - A new devm helper to make adding custom actions simpler (acked by Greg)

* NXP LPC1850 CREG clocks
The NXP LPC18xx/43xx CREG (Configuration Registers) block contains
control registers for two low speed clocks. One of the clocks is a
32 kHz oscillator driver with power up/down and clock gating. Next
is a fixed divider that creates a 1 kHz clock from the 32 kHz osc.
These clocks are used by the RTC and the Event Router peripherials.
The 32 kHz can also be routed to other peripherials to enable low
power modes.
This binding uses the common clock binding:
Documentation/devicetree/bindings/clock/clock-bindings.txt
Required properties:
- compatible:
Should be "nxp,lpc1850-creg-clk"
- #clock-cells:
Shall have value <1>.
- clocks:
Shall contain a phandle to the fixed 32 kHz crystal.
The creg-clk node must be a child of the creg syscon node.
The following clocks are available from the clock node.
Clock ID Name
0 1 kHz clock
1 32 kHz Oscillator
Example:
soc {
creg: syscon@40043000 {
compatible = "nxp,lpc1850-creg", "syscon", "simple-mfd";
reg = <0x40043000 0x1000>;

compatible = "nxp,lpc1850-creg-clk";
clocks = <&xtal32>;
#clock-cells = <1>;

Binding for Texas Instruments ADPLL clock.
Binding status: Unstable - ABI compatibility may be broken in the future
This binding uses the common clock binding[1]. It assumes a
register-mapped ADPLL with two to three selectable input clocks
and three to four children.
[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
Required properties:
- compatible : shall be one of "ti,dm814-adpll-s-clock" or
"ti,dm814-adpll-lj-clock" depending on the type of the ADPLL
- #clock-cells : from common clock binding; shall be set to 1.
- clocks : link phandles of parent clocks clkinp and clkinpulow, note
that the adpll-s-clock also has an optional clkinphif
- reg : address and length of the register set for controlling the ADPLL.
Examples:
adpll_mpu_ck: adpll@40 {
#clock-cells = <1>;
compatible = "ti,dm814-adpll-s-clock";
reg = <0x40 0x40>;
clocks = <&devosc_ck &devosc_ck &devosc_ck>;
