Gunar Schorcht	4fcfb7ca06	cpu/esp8266: i2c improvements ... The commit - improves the timing of the SDA and SCL signals that fixes communication problems with some slaves (#10115), - introduces the internal function _i2c_clear which clears the bus when SDA line is locked at LOW, and - renames internal _i2c_*_sda and _i2c_*_scl functions to function names that are more clear, e.g., _i2c_clear_sda to _i2c_sda_low.	2018-10-10 12:17:20 +02:00
