Subject: [PATCH v9 6/6] arm64: dts: marvell: armada-37xx: add device node for UART clock and use it
Date: Sat, 19 Feb 2022 16:28:18 +0100	[thread overview]
Message-ID: <20220219152818.4319-7-kabel@kernel.org> (raw)
In-Reply-To: <20220219152818.4319-1-kabel@kernel.org>

From: Pali Rohár <pali@kernel.org>

Define DT node for UART clock "marvell,armada-3700-uart-clock" and use
this UART clock as a base clock for all UART devices.
