Subject: [PATCH v2 0/2] clk: meson: mark clk81 as critical
Date: Wed, 24 May 2017 11:39:30 +0200	[thread overview]
Message-ID: <20170524093932.5262-1-jbrunet@baylibre.com> (raw)

The GX (gxbb.c) clock controller driver already marks the clk81 clock
as criticial. However, the Meson8b clock controller driver does not do
this yet.
This can lead to a freeze of the whole system when clk81 is disabled
by the common clock framework (for example after the last child clock
is disabled by a driver which used that child clock).

Changes since v1: [0]
With the clock flagged as CRITICAL, CLK_IGNORE_UNUSED is no longer
useful. Remove this flag from meson8b and gxbb's clk81.
