We have connected Accelerometer on I2C3 of OMAP3430. We are using 2.6.29 kernel from git://git.omapzoom.org. When we are trying to retreive data from Accelerometer we are getting error saying "i2c_omap i2c_omap.3: timeout waiting for bus ready". This has resulted in Kernel panic. I have attached the Kernel panic log.
Also referred few discussions on the same lines...
http://patchwork.kernel.org/patch/49514/
The above mentioned patch is already being applied to kernel. Please let me know if anyone already faced similar proble with respect to I2C3. Also if any patches which can be incorporated for the same.
