From 05caac5f388bf0b821d4a75e480a74ae40fc8478 Mon Sep 17 00:00:00 2001 From: Martin Sperl Date: Fri, 2 Sep 2016 16:45:27 +0100 Subject: [PATCH] Register the clocks early during the boot process, so that special/critical clocks can get enabled early on in the boot process avoiding the risk of disabling a clock, pll_divider or pll when a claiming driver fails to install propperly - maybe it needs to defer.
