From 4a606af20d930dc1a8b62b0f753cdc018914e5de Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Wed, 11 Dec 2013 15:13:54 +0100 Subject: [PATCH] ARM: shmobile: lager-reference: Instantiate clkdevs for SCIF and CMT Now that the common clock framework is supported, the clock lookup entries in clock-r8a7790.c are not registered anymore. Devices must instead reference their clocks in the device tree. However, SCIF and CMT devices are still instantiated through platform code, and thus need a clock lookup entry. Retrieve the SCIF and CMT clock entries by name and register clkdevs for the corresponding devices. This will be removed when the SCIF and CMT devices will be instantiated from the device tree.
