Subject: [PATCH linux v1 0/4] Seven segment display support
Date: Tue, 13 Dec 2016 23:55:00 -0800	[thread overview]
Message-ID: <1481702104-8617-1-git-send-email-jaghu@google.com> (raw)

This patchset includes:

Documentation for the binding which provides an interface for adding clock,
data and clear signal GPIO lines to control seven segment display.

The platform device driver 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.

The character device driver 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.

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

The platform driver matches on the device tree node; the platform driver also
initializes the character device.

Tested that the seven segment display works properly by writing to the
character device file on a EVB AST2500 board which also has 74HC164 wired
to two 7-segment displays.
