Subject: [PATCH v3 06/10] arm: dts: k3-am642-*-evm: Add USB support
Date: Fri, 4 Jun 2021 22:00:36 +0530 [thread overview]
Message-ID: <20210604163043.12811-7-a-govindraju@ti.com> (raw)
In-Reply-To: <20210604163043.12811-1-a-govindraju@ti.com>
AM64 EVM board has a micro USB 2.0 AB connector and the USB0_VBUS is
connected with a resistor divider in between. USB0_DRVVBUS pin is muxed
between USB0_DRVVBUS and GPIO1_79 signals.
Add the corresponding properties and set the pinmux mode for USB subsystem
in the evm dts file.
