title: python smbus/i2c frequency
body: <p>I would like to change i2c bus frequency in order to allow for slightly longer cables.</p>
  
  <p>I am using python-smbus package and it does work very well, however, I am unable to find how to set the bus frequency.</p>
  
  <p>I have looked through the <a href="http://wiki.erazor-zone.de/wiki%3alinux%3apython%3asmbus%3adoc" rel="nofollow">docs</a> but was unable to find anything even remotely related to setting bus parameters.</p>
  
  <p>Is that anything that could be done in python or do I need something lower level?</p>
  
  <p>I am using Raspberry PI, which is an ARM architecture.</p>
