Pull clk updates from Stephen Boyd: "This round of clk driver and framework updates is heavy on the driver update side. The two main highlights in the core framework are the addition of an bulk clk_get API that handles optional clks and an extra debugfs file that tells the developer about the current parent of a clk. The driver updates are dominated by i.MX in the diffstat, but that is mostly because that SoC has started converting to the clk_hw style of clk registration. The next big update is in the Amlogic meson clk driver that gained some support for audio, cpu, and temperature clks while fixing some PLL issues. Finally, the biggest thing that stands out is the conversion of a large part of the Allwinner sunxi-ng driver to the new clk parent scheme that uses less strings and more pointer comparisons to match clk parents and children up. In general, it looks like we have a lot of little fixes and tweaks here and there to clk data along with the normal addition of a handful of new drivers and a couple new core framework features.

+Binding for Silicon Labs Si5341 and Si5340 programmable i2c clock generator.
+
+Reference
+[1] Si5341 Data Sheet
+    https://www.silabs.com/documents/public/data-sheets/Si5341-40-D-DataSheet.pdf
+[2] Si5341 Reference Manual
+    https://www.silabs.com/documents/public/reference-manuals/Si5341-40-D-RM.pdf
+
+The Si5341 and Si5340 are programmable i2c clock generators with up to 10 output
+clocks. The chip contains a PLL that sources 5 (or 4) multisynth clocks, which
+in turn can be directed to any of the 10 (or 4) outputs through a divider.
+The internal structure of the clock generators can be found in [2].
+
+The driver can be used in "as is" mode, reading the current settings from the
+chip at boot, in case you have a (pre-)programmed device. If the PLL is not
+configured when the driver probes, it assumes the driver must fully initialize
+it.
+
+The device type, speed grade and revision are determined runtime by probing.
+
+The driver currently only supports XTAL input mode, and does not support any
+fancy input configurations. They can still be programmed into the chip and
+the driver will leave them "as is".
+
+==I2C device node==
+
+Required properties:
+- compatible: shall be one of the following:
+	"silabs,si5340" - Si5340 A/B/C/D
+	"silabs,si5341" - Si5341 A/B/C/D
+- reg: i2c device address, usually 0x74
+- #clock-cells: from common clock binding; shall be set to 2.
+	The first value is "0" for outputs, "1" for synthesizers.
+	The second value is the output or synthesizer index.
+- clocks: from common clock binding; list of parent clock  handles,
+	corresponding to inputs. Use a fixed clock for the "xtal" input.
+	At least one must be present.
+- clock-names: One of: "xtal", "in0", "in1", "in2"
+- vdd-supply: Regulator node for VDD
+
+Optional properties:
+- vdda-supply: Regulator node for VDDA
+- vdds-supply: Regulator node for VDDS
+- silabs,pll-m-num, silabs,pll-m-den: Numerator and denominator for PLL
+  feedback divider. Must be such that the PLL output is in the valid range. For
+  example, to create 14GHz from a 48MHz xtal, use m-num=14000 and m-den=48. Only
+  the fraction matters, using 3500 and 12 will deliver the exact same result.
+  If these are not specified, and the PLL is not yet programmed when the driver
+  probes, the PLL will be set to 14GHz.
+- silabs,reprogram: When present, the driver will always assume the device must
+  be initialized, and always performs the soft-reset routine. Since this will
+  temporarily stop all output clocks, don't do this if the chip is generating
+  the CPU clock for example.
+- interrupts: Interrupt for INTRb pin.
+- #address-cells: shall be set to 1.
+- #size-cells: shall be set to 0.
+
+
+== Child nodes: Outputs ==
+
+The child nodes list the output clocks.
+
+Each of the clock outputs can be overwritten individually by using a child node.
+If a child node for a clock output is not set, the configuration remains
+unchanged.
+
+Required child node properties:
+- reg: number of clock output.
+
+Optional child node properties:
+- vdd-supply: Regulator node for VDD for this output. The driver selects default
+	values for common-mode and amplitude based on the voltage.
+- silabs,format: Output format, one of:
+	1 = differential (defaults to LVDS levels)
+	2 = low-power (defaults to HCSL levels)
+	4 = LVCMOS
+- silabs,common-mode: Manually override output common mode, see [2] for values
+- silabs,amplitude: Manually override output amplitude, see [2] for values
+- silabs,synth-master: boolean. If present, this output is allowed to change the
+	multisynth frequency dynamically.
+- silabs,silabs,disable-high: boolean. If set, the clock output is driven HIGH
+	when disabled, otherwise it's driven LOW.

-Allwinner Clock Control Unit Binding
------------------------------------

-		- "allwinner,sun5i-a13-ccu"

-		- "allwinner,sun50i-h6-r-ccu"
-		- "allwinner,suniv-f1c100s-ccu"
-		- "nextthing,gr8-ccu"
-
- reg: Must contain the registers base address and length
- clocks: phandle to the oscillators feeding the CCU. Two are needed:
-  - "hosc": the high frequency oscillator (usually at 24MHz)
-  - "losc": the low frequency oscillator (usually at 32kHz)
-	    On the A83T, this is the internal 16MHz oscillator divided by 512
- clock-names: Must contain the clock names described just above
- #clock-cells : must contain 1
- #reset-cells : must contain 1
-
-For the main CCU on H6, one more clock is needed:
- "iosc": the SoC's internal frequency oscillator
-
-For the PRCM CCUs on A83T/H3/A64/H6, two more clocks are needed:
- "pll-periph": the SoC's peripheral PLL from the main CCU
- "iosc": the SoC's internal frequency oscillator
-
-Example for generic CCU:
-ccu: clock@1c20000 {
-	compatible = "allwinner,sun8i-h3-ccu";
-	reg = <0x01c20000 0x400>;
-	clocks = <&osc24M>, <&osc32k>;
-	clock-names = "hosc", "losc";
-	#clock-cells = <1>;
-	#reset-cells = <1>;
-};
-
-Example for PRCM CCU:
-r_ccu: clock@1f01400 {
-	compatible = "allwinner,sun50i-a64-r-ccu";
-	reg = <0x01f01400 0x100>;
-	clocks = <&osc24M>, <&osc32k>, <&iosc>, <&ccu CLK_PLL_PERIPH0>;
-	clock-names = "hosc", "losc", "iosc", "pll-periph";
-	#clock-cells = <1>;
-	#reset-cells = <1>;
