From 5a9aaf0cf89dfb776f45b7ef878fd1508faadbf7 Mon Sep 17 00:00:00 2001 From: Andy Green Date: Sun, 10 Jul 2011 05:27:15 -0600 Subject: I2C: OMAP1/OMAP2+: create omap I2C functionality flags for each cpu_... test These represent the 8 kinds of implementation functionality that up until now were inferred by the 16 remaining cpu_...() tests in the omap i2c driver. Changed to use BIT() as suggested by Balaji T Krishnamoorthy.
