[PATCH linux v4 0/3] Seven segment display support

[Jaghathiswari Rankappagounder Natarajan]

This patchset includes:

Character device driver which implements the user-space API for letting a user
write to two 7-segment displays including any conversion methods necessary
to map the user input to two 7-segment displays.

Platform device driver which provides an API for displaying on two 7-segment
displays, and implements the required bit-banging. The hardware assumed is
74HC164 wired to two 7-segment displays.

Adding clock, data and clear signal lines in the devicetree to control
seven segment display on zaius platform.

A changelog between versions is included in the individual patches. Please
provide feedback.

Thanks,
Jagha
