| * | i2c-s3c2410: Add HDMIPHY quirk for S3C2440Karol Lewandowski2012-05-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for s3c2440 I2C bus controller dedicated HDMIPHY device on Exynos4 platform. Some quirks are introduced due to differences between HDMIPHY and other I2C controllers on Exynos4. These differences are: - no GPIOs, HDMIPHY is inside the SoC and the controller is connected internally - due to unknown reason (probably HW bug in HDMIPHY and/or the controller) a transfer fails to finish. The controller hangs after sending the last byte, the workaround for this bug is resetting the controller after each transfer Signed-off-by: Tomasz Stanislawski <t.stanislaws@samsung.com> Signed-off-by: Karol Lewandowski <k.lewandowsk@samsung.com> Tested-by: Tomasz Stanislawski <t.stanislaws@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Signed-off-by: Wolfram Sang <w.sang@pengutronix.de>

| * | i2c: muxes are not EXPERIMENTAL anymoreWolfram Sang2012-05-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We got multiple patches to add mux support to device tree, so people are using it happily already and build up on it. I also used it in a project without encountering problems. 20 months of EXPERIMENTAL should do for this.

| * | i2c/of: Automatically populate i2c mux busses from device tree data.David Daney2012-05-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For 'normal' i2c bus drivers, we can call of_i2c_register_devices() and have the device tree framework automatically populate the bus with the devices specified in the device tree. This patch adds a common code to the i2c mux framework to have the mux sub-busses be populated by the of_i2c_register_devices() too. If the mux device has an of_node, we populate the sub-bus' of_node so that the subsequent call to of_i2c_register_devices() will find the corresponding devices. It seemed better to put this logic in i2c_add_mux_adapter() rather than the individual mux drivers, as they will all probably want to do the same thing.

The other platforms are continuing the process. We finally start to see the payback on this investment, as new machines are getting supported purely by adding a .dts source file that can be completely independent of the kernel source."

* | | i2c: mxs: disable QUEUE when sending is doneWolfram Sang2012-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the last fixes to this driver ensure now the queue termination is done correctly, we can finally disable the queue after a transfer without problems. The gain is that it will only be reenabled after the next transfer is fully set up. Before, the queue was running all the time and if the setup of the next message was interrupted by another thread, an incomplete buffer could have been sent, padded with zeroes.

So, I modified like this patch. Modifying like this patch, I've never seen the timeout event with high load test.

* | | i2c: tegra: Add delay before resetting the controller after NACKAlok Chauhan2012-04-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NACK interrupt is generated before I2C controller generates the STOP condition on bus. Because of this reset of controller is happening before I2C controller could complete STOP condition. So wait for some time before resetting the controller so that STOP condition has delivered properly on bus. Added delay of 2 clock period before resetting the controller in case of NACK error.
