Subject: [PATCH v11 15/18] dt-bindings: clock: imx8m-clock: add PLLs
Date: Wed, 23 Apr 2025 08:02:32 +0200 [thread overview]
Message-ID: <20250423060241.95521-16-dario.binacchi@amarulasolutions.com> (raw)
In-Reply-To: <20250423060241.95521-1-dario.binacchi@amarulasolutions.com>
Though adding the PLLs to clocks and clock-names properties will break
the ABI, it is required to accurately describe the hardware. Indeed,
the Clock Control Module (CCM) receives clocks from the PLLs and
oscillators and generates clocks for on-chip peripherals.
