2011-12-19i2c: tegra: Support DVC controller in device treeStephen Warren
One of the Tegra I2C blocks is inside the DVC (Digital Voltage Controller) block. This block is identical to the rest of the I2C blocks, except that it only supports master mode, it has registers moved around, and it needs some extra init to get it into I2C mode. The register moves are handled by i2c_readl and i2c_writel This patch adds a new compatible value for controllers of this "DVC" type; I figured that this approach was reasonable, as opposed to adding an is-dvc property under the existing compatible value, since the HW truly is different. v2: Call of_device_is_compatible() to determine is_dvc, instead of storing the flag in tegra_i2c_of_match[]'s .data field.

2011-12-18i2c-eg20t: correct the driver init order of pch_i2c_probe()Feng Tang
Before registering an adapter to i2c subsystem, we need make sure driver is ready for incoming i2c xfer, becasue the i2c_add_adapter() may trigger a i2c device driver's proble function which may start some real i2c xfer. I met this issue when integrating a TSC2007 i2c touch screen device with the i2c-eg20t driver. This patch will call request_irq() and hw init before calling i2c_add_adapter().

2011-12-18i2c-s3c2410: Fix return code of s3c24xx_i2c_parse_dt_gpioTushar Behera
s3c24xx_i2c_parse_dt_gpio is called when cfg_gpio is not defined in the platform data of the i2c device. When DT is not enabled, the above function always returns -EINVAL. Since there can be some i2c devices which don't need to configure any gpio lines, the probe of such devices would fail here. Changing the default return value to success would fix this issue.

2011-10-30i2c-algo-bit: Let user test buses without failingJean Delvare
Always failing to register I2C buses when the line testing fails is a little harsh. While such a failure is definitely a bug in the driver that exposes the affected I2C bus, things may still work fine if the missing initialization steps are done later, before the I2C bus is used. So it seems a better debugging tool to just report the test failure by default. I introduce bit_test=2 if anyone really misses the original behavior of bit_test=1.

2011-10-29i2c-au1550: increase timeout waiting for master doneManuel Lauss
Double the timeout in the loop which busy-waits for the "master-done" bit to be set. This bit indicates whether an i2c transaction has completed; on the DB1300 and DB1550 boards this timeout is slightly too short and causes transactions to the WM8731 codec to be falsely flagged as failed. The timeout itself is necessary since transactions to non-existant slaves never set this bit in the first place (and cause i2cdetect to hang). With this change the WM8731 codec on the DB1300/DB1550 boards is correctly detected and initialized.
