Subject: [PATCH 2/3] clk: meson: gxbb: no spread spectrum on mpll0
Date: Fri, 29 Mar 2019 16:33:24 +0100 [thread overview]
Message-ID: <20190329153325.23869-3-jbrunet@baylibre.com> (raw)
In-Reply-To: <20190329153325.23869-1-jbrunet@baylibre.com>
The documentation says there is an SSEN bit on mpll0 but, after testing
it, no spread spectrum function appears to be enabled by this bit on any
of the MPLLs.
Let's remove it until we know more
Fixes: 1f737ffa13ef ("clk: meson: mpll: fix mpll0 fractional part ignored")
