Subject: [PATCH 2/2] Input: bcm-keypad: Add Broadcom keypad controller
Date: Mon, 9 Feb 2015 16:07:41 -0800 [thread overview]
Message-ID: <1423526861-29579-3-git-send-email-sbranden@broadcom.com> (raw)
In-Reply-To: <1423526861-29579-1-git-send-email-sbranden@broadcom.com>
Add driver for Broadcom's keypad controller.
Broadcom Keypad controller is used to interface a SoC with a matrix-type
keypad device. The keypad controller supports multiple row and column lines.
A key can be placed at each intersection of a unique row and a unique column.
The keypad controller can sense a key-press and key-release and report the
event using a interrupt to the cpu.
