Subject: [PATCH v3 09/10] arm64: dts: sparx5: Add Sparx5 SoC DPLL clock
Date:   Mon, 15 Jun 2020 15:32:41 +0200
Message-ID: <20200615133242.24911-10-lars.povlsen@microchip.com>

This adds a DPLL clock to the Sparx5 SoC. It is used to generate clock
to misc peripherals, specifically the SDHCI/eMMC controller.
