Subject: [PATCH 2/3] clk: meson: meson8b: rename cpu_div2/cpu_div3 to cpu_in_div2/cpu_in_div3
Date: Fri, 16 Nov 2018 21:53:02 +0100	[thread overview]
Message-ID: <20181116205303.6354-3-martin.blumenstingl@googlemail.com> (raw)
In-Reply-To: <20181116205303.6354-1-martin.blumenstingl@googlemail.com>

The "cpu_div2" and "cpu_div3" take "cpu_in" as input and divide that by
2 or 3. The clock controller can also generate various CPU clock
post-dividers (2, 3, 4, 5, 6, 7, 8) which are derived from "cpu_clk".
When adding support for these post-dividers our clock naming could be
misleading as we have "cpu_div2" as well as "cpu_clk_div2".
Rename the existing "cpu_in" dividers so the name of the divider's
parent is part of the divider clock's name.
