From 97a0b97f9e8197429eee5f87ce14373f73dbd9d3 Mon Sep 17 00:00:00 2001 From: Peter Griffin Date: Tue, 18 Oct 2016 17:35:00 +0200 Subject: [PATCH] ARM: dts: stih410-clocks: Add PROC_STFE as a critical clock Once the ST frontend demux HW IP has been enabled, the clock can't be disabled otherwise the system will hang and the board will be unserviceable. To allow balanced clock enable/disable calls in the driver we use the critical clock infrastructure to take an extra reference on the clock so the clock will never actually be disabled.
