Subject: [PATCH 02/17] clk: sunxi: Propagate rate changes to parent for mux clocks
Date: Tue, 6 Jan 2015 10:35:12 +0800 [thread overview]
Message-ID: <1420511727-8242-3-git-send-email-wens@csie.org> (raw)
In-Reply-To: <1420511727-8242-1-git-send-email-wens@csie.org>
The cpu clock on sunxi machines is just a mux clock, which is normally
fed by the main PLL, but can be muxed to the main or low power oscillator.
Make the mux clock propagate rate changes to its parent, so we can
change the clock rate of the PLL, and thus actually implement rate
changing on the cpu clock.
This patch also removes the no reparenting limit.
