Subject: [PATCH v2 8/9] clk: meson: mpll: correct N2 maximum value
Date: Thu,  9 Mar 2017 11:41:53 +0100	[thread overview]
Message-ID: <20170309104154.28295-9-jbrunet@baylibre.com> (raw)
In-Reply-To: <20170309104154.28295-1-jbrunet@baylibre.com>

Gxbb datasheet says N2 maximum value is 127 but the register field is
9 bits wide, the maximum value should 511.

Test shows value greater than 127, all the way to 511, works well
