H A Dsoft_i2c.c2ac6985a7466a1c8a7aa8b2fa24d360925a82764 Mon Dec 29 17:36:01 CST 2008 Andrew Dyer <adyer@righthandtech.com> soft_i2c.c add option for repeated start in i2c_read()

This patch adds a #define to optionally change the behaviour of
i2c_read() in soft_i2c.c to send an I2C repeated start instead of a
stop-start between sending the device address pointer write and
reading back the data. The current behaviour is retained as the
default.

While most devices will work either way, I have a smart battery(*)
that requires repeated start, and someone at some point found a
device that required a stop-start.
