* 'for-linus/i2c-33' of git://git.fluff.org/bjdooks/linux: i2c-eg20t: Change-company-name-OKI-SEMICONDUCTOR to LAPIS Semiconductor i2c-eg20t: Support new device LAPIS Semiconductor ML7831 IOH i2c-eg20t: modified the setting of transfer rate. i2c-eg20t: use i2c_add_numbered_adapter to get a fixed bus number i2c: OMAP: Add DT support for i2c controller I2C: OMAP: NACK without STP I2C: OMAP: correct SYSC register offset for OMAP4

1I2C for OMAP platforms
2
3Required properties :
4- compatible : Must be "ti,omap3-i2c" or "ti,omap4-i2c"
5- ti,hwmods : Must be "i2c<n>", n being the instance number (1-based)
6- #address-cells = <1>;
7- #size-cells = <0>;
8
9Recommended properties :
10- clock-frequency : Desired I2C bus clock frequency in Hz. Otherwise
11 the default 100 kHz frequency will be used.
12
13Optional properties:
14- Child nodes conforming to i2c bus binding
15
16Note: Current implementation will fetch base address, irq and dma
17from omap hwmod data base during device registration.
18Future plan is to migrate hwmod data base contents into device tree
19blob so that, all the required data will be used from device tree dts
20file.
21
22Examples :
23
24i2c1: i2c@0 {
25 compatible = "ti,omap3-i2c";
26 #address-cells = <1>;
27 #size-cells = <0>;
28 ti,hwmods = "i2c1";
29 clock-frequency = <400000>;
30};
