Subject: [RFC PATCH 0/3] Introduce shared and cbus clocks
Date: Tue, 13 May 2014 17:06:53 +0300	[thread overview]
Message-ID: <1399990023-30318-1-git-send-email-pdeschrijver@nvidia.com> (raw)

Cbus clocks are virtual clocks which implement coordinated changes to
clock rates. They are used to change PLL rates with active child clocks.
On some SoCs (eg. Tegra) this requires the active child clocks to be moved
to a different parent durint the rate change.

Shared clocks are virtual clocks which implement clock policies such as
minimum required rate or maximum allowed rate.
