Subject: [PATCH 01/20] clk: fixed-factor: Pass clk rates change to the parent
Date: Mon, 16 May 2016 14:47:01 +0200	[thread overview]
Message-ID: <1463402840-17062-2-git-send-email-maxime.ripard@free-electrons.com> (raw)
In-Reply-To: <1463402840-17062-1-git-send-email-maxime.ripard@free-electrons.com>

A fixed factor clock, if it needs to change its rate, by definition do not
have any choice but to modify its parent rate.

Add the CLK_SET_RATE_PARENT flag to that clock so that it can happen
