Subject: [PATCH v3 5/9] clk: si5341: Update initialization magic
Date: Thu, 25 Mar 2021 13:26:39 -0600	[thread overview]
Message-ID: <20210325192643.2190069-6-robert.hancock@calian.com> (raw)
In-Reply-To: <20210325192643.2190069-1-robert.hancock@calian.com>

Update the default register settings to include the VCO_RESET_CALCODE
settings (set by the SiLabs ClockBuilder software but not described in
the datasheet). Also update part of the initialization sequence to match
ClockBuilder and the datasheet.

Fixes: 3044a860fd ("clk: Add Si5341/Si5340 driver")
Signed-off-by: Robert Hancock <robert.hancock@calian.com>
