Giorgio Groß	4d78593a0f	Merged in ordsen/nuttx/feature-pca9540bdp-i2cmultiplexer (pull request #610) ... Feature pca9540bdp i2cmultiplexer * Implement common i2c multiplexer abstraction to be reused by i2c multiplexer devices. Provide common interface with transfer and reset calls to set up virtual i2c busses. * Remove i2cmux_lower_half.c and headers, will be implemented by each mux driver * Implement PCA9540BDP I2C multiplexer lower half which uses the common i2c mux abstraction * Remove application interface and implement common i2c functions * Remove application interface from pca driver and implement common i2c functions directly in the pca driver * Use i2cerr Approved-by: Gregory Nutt <gnutt@nuttx.org>	2018-03-05 16:11:05 +00:00
