Subject: [PATCH 1/4] ARM: dts: stm32: Add alternate pinmux for ethernet0 pins
Date: Wed, 6 Jan 2021 21:43:44 +0100 [thread overview]
Message-ID: <20210106204347.475920-1-marex@denx.de> (raw)
Add another mux option for ethernet0 pins, this is used on DHCOM when
the ethernet PHY 50 MHz clock is generated by the MCO2 on PG2 pin and
then fed back via PA1 pin.
