From 24b4e07df54b7bf7739fb3dd193f639a8f274ad6 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Fri, 14 Feb 2014 00:35:18 +0100 Subject: clocksource: sh_cmt: Rename clock to "fck" in the non-legacy case The sh_cmt driver gets the CMT functional clock using a connection ID of "cmt_fck". While all SH SoCs create clock lookup entries with a NULL device ID and a "cmt_fck" connection ID, the ARM SoCs use the device ID only with a NULL connection ID. This works on legacy platforms but will break on ARM with DT boot. Fix the situation by using a connection ID of "fck" in the non-legacy platform data case. Clock lookup entries will be renamed to use the device ID as well as the connection ID as platforms get moved to new platform data. The legacy code will eventually be dropped, leaving us with device ID based clock lookup, compatible with DT boot.
