+From 5d71f0466358d7517a65fe8962eb82d9aca8cc54 Mon Sep 17 00:00:00 2001

+Subject: [PATCH 018/194] 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.
