Subject: [PATCH v3 0/2] clocksource: npcm: add NPCM7xx timer driver

Addressed comments from:.
- Daniel Lezcano: https://www.spinics.net/lists/devicetree/msg196683.html
- Brendan Higgins: https://www.spinics.net/lists/devicetree/msg201038.html
https://www.spinics.net/lists/devicetree/msg201037.html

Changes since version 2:
- The shutdown function called oneshot function that can cause a crash
in the system.
Modify shutdown call to unique shutdown function to solve it.
- Adding support to resume function
- Using timer-of.c API
- Modify NPCM750 compatible name.

Asked Brendon to modify NPCM7xx device tree entry.
https://lkml.org/lkml/2017/11/6/335

Changes have been tested on the NPCM750 evaluation board.

+Nuvoton NPCM7xx timer
+
+Nuvoton NPCM7xx have three timer modules, each timer module provides five 24-bit
+timer counters.
+
+Required properties:
+- compatible : "nuvoton,npcm750-timer" for Poleg NPCM750.
+- reg : Offset and length of the register set for the device.
+- interrupts : Contain the timer interrupt with flags for
+ falling edge.
+
+Required clocking property, have to be one of:
+- clocks : phandle of timer reference clock.
+- clock-frequency : The frequency in Hz of the clock that drives the NPCM7xx
+ timer (usually 25000000).
+
+Example:
+
+timer@f0008000 {
+ compatible = "nuvoton,npcm750-timer";
+ interrupts = <GIC_SPI 32 IRQ_TYPE_LEVEL_HIGH>;
+ reg = <0xf0008000 0x1000>;
+ clocks = <&clk NPCM7XX_CLK_TIMER>;
+};
