Quoting Jerome Brunet (2017-05-24 02:39:30)

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.

Both patches look good to me.

Regards,
Mike
