+ * New i2c_read, i2c_write and i2c_probe functions, tested on OMAP4
+ * (4430/60/70), OMAP5 (5430) and AM335X (3359); should work on older
+ * OMAPs and derivatives as well. The only anticipated exception would
+ * be the OMAP2420, which shall require driver modification.
+ * - Rewritten i2c_read to operate correctly with all types of chips
+ *   (old function could not read consistent data from some I2C slaves).
+ * - Optimized i2c_write.
+ * - New i2c_probe, performs write access vs read. The old probe could
+ *   hang the system under certain conditions (e.g. unconfigured pads).
+ * - The read/write/probe functions try to identify unconfigured bus.
+ * - Status functions now read irqstatus_raw as per TRM guidelines
+ *   (except for OMAP243X and OMAP34XX).
+ * - Driver now supports up to I2C5 (OMAP5).
