Implement a generalized I2C transmit-receive function that write-then-read blocks of raw data. Original 8-bit and 16-bit read/write functions are refactored. SMBus read-block protocol for ASCII string is also implemented based on this API. Signed-off-by: Rong Chang <rongchang@chromium.org> BUG=chrome-os-partner:8026,8316 TEST=manual: Type 'lightsaber' to check 8-bit read/write. Type 'charger' to check 16-bit read. Type 'charger input 4032' to check 16-bit write. Change-Id: I0ad3ad45b796d9ec03d8fbc1d643aa6a92d6343f
- EC Lib
This wraps Blizzard driverlib and implements the EC chip interface defined
by Google. See below diagram for architecture.
