| 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 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@80000 { |
| compatible = "nuvoton,npcm750-i2c"; |
| 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>; |
| }; |
