      i2c: mxs: fix broken timing calculation · 869c6a3e
      Lothar Waßmann authored
      The timing calculation is rather bogus and gives extremely wrong
      results for higher frequencies (on an i.MX28). E.g. instead of 400 kHz
      I measured 770 kHz.
      
      Implement a calculation that adheres to the I2C spec and gives exact
      results for I2C frequencies from 12.56 kHz to 960 kHz.
      
      Also the bus_free and leadin parameters are programmed according to
      the I2C spec for standard and fast mode.
      
      This was tested on a Ka-Ro TX28 module with a DS1339, TSC2007, PCA9554
      and SGTL5000 client.
