Subject: [PATCH v4 2/9] dt-bindings: clk: at91: add audio plls to the compatible list
Date: Tue, 25 Jul 2017 09:37:03 +0200	[thread overview]
Message-ID: <ab59b9d6b4bcd3a26672ce83e379f49c551eb9ba.1500968090.git-series.quentin.schulz@free-electrons.com> (raw)
In-Reply-To: <cover.c8ce78c15296190b2aa5c452c0c4512528e28518.1500968090.git-series.quentin.schulz@free-electrons.com>
In-Reply-To: <cover.c8ce78c15296190b2aa5c452c0c4512528e28518.1500968090.git-series.quentin.schulz@free-electrons.com>

This new clock driver set allows to have a fractional divided clock that
would generate a precise clock particularly suitable for audio
applications.

The main audio pll clock has two children clocks: one that is connected
to the PMC, the other that can directly drive a pad. As these two routes
have different enable bits and different dividers and divider formulas,
they are handled by two different drivers.

This adds the audio plls (frac, pad and pmc) to the compatible list of
at91 clocks in DT binding.
