From mboxrd@z Thu Jan 1 00:00:00 1970 From: jbrunet@baylibre.com (Jerome Brunet) Date: Wed, 24 May 2017 11:39:31 +0200 Subject: [PATCH v2 1/2] clk: meson: meson8b: mark clk81 as critical In-Reply-To: <20170524093932.5262-1-jbrunet@baylibre.com> References: <20170524093932.5262-1-jbrunet@baylibre.com> Message-ID: <20170524093932.5262-2-jbrunet@baylibre.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Martin Blumenstingl 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).
