From fb76dd10b91146e9cefbb3cd4e6812c5a95ee43b Mon Sep 17 00:00:00 2001 From: Luotao Fu Date: Thu, 10 Jun 2010 12:05:23 -0700 Subject: Input: matrix_keypad - add support for clustered irq This one adds support of a combined irq source for the whole matrix keypad. This can be useful if all rows and columns of the keypad are e.g. connected to a GPIO expander, which only has one interrupt line for all events on every single GPIO.
