Subject: [PATCH v4 02/13] clk: composite: allow read-only clocks
Date: Sun, 22 Jun 2014 22:43:35 +0200 [thread overview]
Message-ID: <3089033.Y3HT2Lq8qX@diego> (raw)
In-Reply-To: <1808429.dNxms7FR7U@diego>
This allows readl-only composite clocks by making mux_ops->set_parent and
divider_ops->round_rate/set_rate optional.
