These new functions are built for OMAP4 and OMAP5 only. The major improvement is that the new i2c_read fixes the inability to read correctly from certain types of I2C chips.
- Rewritten i2c_read to operate correctly with all types of chips.
- Optimized i2c_write. Both read/write functions try to identify unconfigured bus.
- New i2c_probe performs write access vs read. Optionally selectable via CONFIG_I2C_PROBE_WRITE.
- Driver supports up to I2C5 (OMAP5; I2C_BASE5 must be defined).

So, I've tested the i2c_probe on the was failing last time we tried a write-style probe and it's OK. But I'm not sure that we're obeying the comments I spell out in 168a5acb81a8d92a7effcb2727aaa89367b97e05 about why we can't do a write-style probe all the same. Can you be sure we're following the constraints there? Thanks!
