From fa6415affe2020606799fd4e9e89f37a01fb2ae9 Mon Sep 17 00:00:00 2001 From: Lee Jones Date: Tue, 7 Jun 2016 12:19:25 +0100 Subject: [PATCH] clk: st: clk-flexgen: Detect critical clocks Utilise the new Critical Clock infrastructure to mark clocks which much not be disabled as CRITICAL. While we're at it, reduce the coverage of the flex_flags variable, since it's only really used in a single for() loop.
