Merge tag 'samsung-drivers-exynos5440-4.19' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into next/drivers

Exynos5440 drivers removal

The Exynos5440 (quad-core A15 with GMAC, PCIe, SATA) was targeting
server platforms but it did not make it to the market really.  There are
no development boards with it and probably there are no real products
neither.  The development for Exynos5440 ended in 2013 and since then
the platform is in maintenance mode.

Removing Exynos5440 makes our life slightly easier: less maintenance,
smaller code, reduced number of quirks, no need to preserve DTB
backward-compatibility.

The Device Tree sources and some of the drivers for Exynos5440 were
already removed.  This removes remaining drivers.

* Samsung Exynos5440 Clock Controller



The Exynos5440 clock controller generates and supplies clock to various

controllers within the Exynos5440 SoC.



Required Properties:



- compatible: should be "samsung,exynos5440-clock".



- reg: physical base address of the controller and length of memory mapped

  region.



- #clock-cells: should be 1.



Each clock is assigned an identifier and client nodes can use this identifier

to specify the clock which they consume.



All available clocks are defined as preprocessor macros in

dt-bindings/clock/exynos5440.h header and can be used in device

tree sources.



Example: An example of a clock controller node is listed below.



	clock: clock-controller@10010000 {

		compatible = "samsung,exynos5440-clock";

		reg = <0x160000 0x10000>;

		#clock-cells = <1>;

	};

Exynos5440 cpufreq driver

-------------------



Exynos5440 SoC cpufreq driver for CPU frequency scaling.



Required properties:

- interrupts: Interrupt to know the completion of cpu frequency change.

- operating-points: Table of frequencies and voltage CPU could be transitioned into,

	in the decreasing order. Frequency should be in KHz units and voltage

	should be in microvolts.



Optional properties:

- clock-latency: Clock monitor latency in microsecond.



All the required listed above must be defined under node cpufreq.



Example:

--------

	cpufreq@160000 {

		compatible = "samsung,exynos5440-cpufreq";

		reg = <0x160000 0x1000>;

		interrupts = <0 57 0>;

		operating-points = <

				1000000 975000

				800000  925000>;

		clock-latency = <100000>;

	};
