Subject: [PATCH v3 2/7] dt-bindings: clock: meson: a1: pll: introduce new syspll bindings
Date: Wed, 15 May 2024 21:47:25 +0300 [thread overview]
Message-ID: <20240515185103.20256-3-ddrokosov@salutedevices.com> (raw)
In-Reply-To: <20240515185103.20256-1-ddrokosov@salutedevices.com>
The 'syspll' PLL is a general-purpose PLL designed specifically for the
CPU clock. It is capable of producing output frequencies within the
range of 768MHz to 1536MHz.
The 'syspll_in' source clock is an optional parent connection from the
peripherals clock controller.
