rpi: add uart device_path #842
Conversation

The change is technically trivial and looks ok to me, but are you sure the path is the same on RasPi 1 & 2, in addition to 3? Quick googling gives me this may be a RasPi 3 thing and on older versions the port was either On the other hand, if it wasn't there at all, it didn't work anyway, so having a wrong one would do no harm. |
Currently there is no device_path registered for UART in Raspberry Pi source. This will hinder the working of UART driver in mraa. So, register the device_path with '/dev/ttyS0' for all the raspberry pi models except Rpi3. For Rpi3 'dev/serial0' is used as most of the raspbian images make this as a symlink to _real_ UART port by default.

@kvkdileep Can you do a quick test now? |

@Mani-Sadhasivam spare me some time, i will test it with sensor having uart interface |

@kvkdileep have you had a chance to test this? |

@kvkdileep did this work? |
|
@kvkdileep, are you still up to checking this one out? That's the last step before merging as everything else looks ok (Travis failure is unrelated to the change contents). |

If this was tested I'm OK to merge! |
