[PATCH 5.10 425/593] clk: si5341: Update initialization magic
From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Date: 2021-07-12 07:09:33

lkml
Subsystem:
common clk framework, the rest · Maintainers:
Michael Turquette, Stephen Boyd, Linus Torvalds
From: Robert Hancock <redacted>
[ Upstream commit 3c9b49b0031aefb81adfdba5ab0ddf3ca3a2cdc9 ]
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.
