[PATCH v4 1/2] dt-bindings: i2c: npcm7xx: add binding for i2c controller
Nuvoton NPCM7XX I2C Controller
NPCM7xx includes 16 I2C controllers. This driver operates the controller.
This module also includes a slave mode, which will be submitted later on.
---
v4 -> v3:
- typo on cover letter.
v3 -> v2:
- fix dt binding: compatible name: omit "bus"
v2 -> v1:
- run check patch in strict mode.
- use linux crc.
- define regs in constant offset without base.
- remove debug prints.
- no declarations for local functions.
v1: initial version

+Nuvoton NPCM7XX I2C bus
+
+The NPCM750x includes sixteen I2C bus controllers. All Controllers support
+both master and slave mode. Each controller has two 16 byte HW FIFO for TX and
+RX.
+
+Required properties:
+- compatible : must be "nuvoton,npcm750-i2c"
+- reg : Offset and length of the register set for the device.
+- interrupts : Contain the I2C interrupt with flags for falling edge.
+- clocks : phandle of I2C reference clock.
+
+Optional:
+- bus-frequency : Contain the I2C bus frequency,
+ the default I2C bus frequency is 10.
+- pinctrl-0 : must be <_pins>, X is module number
+ (on NPCM7XX it's 0 to 15)
+- pinctrl-names : should be set to "default"
+Example:
+
+ i2c0: i2c@8 {
+ compatible = "nuvoton,npcm750-i2c";
+ reg = <0x8 0x1000>;
+ clocks = < NPCM7XX_CLK_APB2>;
+ bus-frequency = <10>;
+ interrupts = ;
