Subject: [PATCH v2 1/2] dt-binding: i2c: npcm7xx: add binding for i2c controller
Date: Tue, 7 Aug 2018 14:07:08 +0300 [thread overview]
Message-ID: <20180807110709.31847-2-tali.perry1@gmail.com> (raw)
In-Reply-To: <20180807110709.31847-1-tali.perry1@gmail.com>
Nuvoton NPCM7XX I2C Controller
NPCM7xx includes 16 I2C contollers. THis driver operates the controller.
This module also includes a slave mode, which will be submitted later on.
Any feedback would be appreciated.
v2 -> v1:
- run check patch in strict mode.
- use linux crc.
- define regs in constant offset without base.
- remove debug prints.
- no declerations for local functions.
v1: initial version

+Nuvoton NPCM7XX I2C bus
+
+The NPCM750x includes sixteen I2C busses
+
+Required properties:
+- compatible : must be "nuvoton,npcm750-i2c-bus"
+- 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 100000.
+- pinctrl-0 : must be <&smbX_pins>, X is module number
+ (on NPCM7XX it's 0 to 15)
+- pinctrl-names : should be set to "default"
+Example:
+
+ i2c0: i2c-bus@80000 {
+ compatible = "nuvoton,npcm750-i2c-bus";
+ reg = <0x80000 0x1000>;
+ clocks = <&clk NPCM7XX_CLK_APB2>;
+ bus-frequency = <100000>;
+ interrupts = <GIC_SPI 64 IRQ_TYPE_LEVEL_HIGH>;
+ pinctrl-names = "default";
+ pinctrl-0 = <&smb0_pins>;
+ };
