From 874b300a6a0bfe97225ed1f8648fa92238e4d9e9 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Tue, 1 Sep 2015 13:59:25 -0700 Subject: [PATCH] ARM: OMAP2+: Fix booting if no timer parent clock is available When bringing up a new SoC we needlessly prevent booting at timer init if timer clock_set_parent fails. This can fail if the system is booting on bootloader configured PLL values until the clock framework driver for the PLL is implemented. Let's just WARN instead, this will provide helpful information for anybody bringing up a new SoC what needs to be fixed. This allows to boot dm814x that's still missing the PLL driver.
