Subject: [PATCH 071/149] 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.
