Enabling I2C1 on the OMAP-L138F

Added by Mostafa Afgani over 10 years ago

Hi, we are attempting to use the I2C1 bus for communicating with some external devices. We made some additions to 'board-mityomapl138.c' in an attempt to enable the bus but still seem to be coming up short. Any suggestions on what is required to enable the I2C1 bus? Is there perhaps a kernel source patch that we can look at?

Thanks in advance.

Looks like the baseboard-recon.c file enables i2c1. See if this helps. Search for references to i2c1.

This was indeed useful for getting the bus enabled. Thanks!
