301 *
302 * An explanation from kayork@mail.utexas.edu:
303 *
304 * During I2C reads, the KS0127 only samples for a stop condition
Hans Verkuil9875c0f2008-09-07 08:00:14 -0300305 * during the place where the acknowledge bit should be. Any standard
Martin Samuelssonfbe60da2006-04-27 10:17:00 -0300306 * I2C implementation (correctly) throws in another clock transition
307 * at the 9th bit, and the KS0127 will not recognize the stop condition
308 * and will continue to clock out data.
309 *
310 * So we have to do the read ourself. Big deal.
Hans Verkuil9875c0f2008-09-07 08:00:14 -0300311 * workaround in i2c-algo-bit
