[PATCH linux v5 0/4] Seven segment display support

[Jaghathiswari Rankappagounder Natarajan]

Hi Joel,
Could you please help review this patch series. Would like to have the
seven segment display driver for testing out on zaius machine.
(I am trying to get the fan tach driver to work and I hope to send that
along with pwm driver for review soon.)

Also you had mentioned about writing the LPC driver. Is that checked in?

Thanks,
Jagha
