[PATCH v2 1/3] dt-bindings: clock: meson8b: describe the embedded reset controller

[narmstrong@baylibre.com (Neil Armstrong)]

Le 22/07/2017 20:58, Martin Blumenstingl a ?crit :
> The Amlogic Meson8/Meson8b/Meson8m2 clock controller provides some reset
> lines. These are used for example to boot the secondary CPU cores.
> 
> This patch describes the reset controller which is embedded into the
> clock controller on these SoCs.
