sys/dev/i2c : i2c_bitbang.c
Log message:
Implement support for "clock stretching" where a slave device pulls down SCL
to slow down the master device. This makes the i2c bit-banging code work
with slow slave device such as SDVO chips and DDC eeproms found on various
graphics hardware supported by inteldrm(4). Mostly from NetBSD.
