Merge branch 'i2c-embedded/for-3.4' of git://git.pengutronix.de/git/wsa/linux
Pull i2c embedded updates from Wolfram Sang: "Nothing special from i2c-embedded for this merge window. Two new drivers, minor feature additions, bugfixes, cleanups. All patches have been in linux-next for some time, too." * 'i2c-embedded/for-3.4' of git://git.pengutronix.de/git/wsa/linux: i2c-eg20t: Remove write-only variables i2c-eg20t: Rework pch_i2c_wait_for_bus_idle to reduce wait time i2c-s3c2410: Add stub runtime power management i2c-s3c2410: Convert to devm_kzalloc() i2c: add CSR SiRFprimaII on-chip I2C controllers driver i2c: tegra: Remove unnecessary write to INT_STATUS i2c: imx: fix imx driver to work though signal is pending i2c: designware: dw_i2c_init_driver as subsys initcall misc: at24: describe platform_data with kernel_doc i2c: Move I2C_EG20T option to the right place. i2c: Support for Netlogic XLR/XLS I2C controller. i2c: mpc: Add support for SMBUS_READ_BLOCK_DATA i2c: versatile: Add Device Tree support

+I2C for SiRFprimaII platforms
+
+Required properties :
+- compatible : Must be "sirf,prima2-i2c"
+- reg: physical base address of the controller and length of memory mapped
+ region.
+- interrupts: interrupt number to the cpu.
+
+Optional properties:
+- clock-frequency : Constains desired I2C/HS-I2C bus clock frequency in Hz.
+ The absence of the propoerty indicates the default frequency 100 kHz.
+
+Examples :
+
+i2c0: i2c@b00e0000 {
+ compatible = "sirf,prima2-i2c";
+ reg = <0xb00e0000 0x10000>;
+ interrupts = <24>;
+};
