From 531be60fc5804318989061178fe8a34eff561e03 Mon Sep 17 00:00:00 2001 From: Tero Kristo Date: Thu, 16 Jun 2016 15:25:18 +0300 Subject: ARM: OMAP2+: timer: add probe for clocksources commit 970f9091d25df14e9540ec7ff48a2f709e284cd1 upstream. A few platforms are currently missing clocksource_probe() completely in their time_init functionality. On OMAP3430 for example, this is causing cpuidle to be pretty much dead, as the counter32k is not going to be registered and instead a gptimer is used as a clocksource. This will tick in periodic mode, preventing any deeper idle states. While here, also drop one unnecessary check for populated DT before existing clocksource_probe() call.
