[PATCH 21/27] ARM: shmobile: r8a7791: Switch to new style CMT device

From: Laurent Pinchart
Date: Thu Feb 13 2014 - 20:00:26 EST


The CMT (Compare Match Timer) driver implements a new style of platform
data that handles the timer as a single device with multiple channel.
Switch from the old-style platform data to the new-style platform data.
