Subject: [PATCH 1/2] arm64: dts: allwinner: h616: Add 32K fanout pin
Date: Sun, 4 Feb 2024 10:32:54 +0100 [thread overview]
Message-ID: <20240204093255.148972-2-andre.przywara@arm.com> (raw)
In-Reply-To: <20240204093255.148972-1-andre.przywara@arm.com>
On some boards the designers saved on a 32KHz crystal for some external
chips, so the SoC has to help out, with providing a 32 KHz clock signal.
Add a pinctrl group node to allow DT nodes to reference this fanout signal.
