Subject: [PATCH 1/1] clk: meson: meson8b: mark clk81 as critical
Date: Thu,  4 May 2017 20:32:01 +0200	[thread overview]
Message-ID: <20170504183201.13175-2-martin.blumenstingl@googlemail.com> (raw)
In-Reply-To: <20170504183201.13175-1-martin.blumenstingl@googlemail.com>

Disabling clk81 results in an immediate freeze of the whole system. This
can happen "accidentally" when the last child-clock of clk81 is disabled
(in this case the common clock framework also disables clk81, even if it
was only enabled indirectly before).
