Subject: [PATCH 2/2] arm64: dts: ti: k3-j784s4-evm: Add pinmux information for ADC
Date: Wed, 12 Apr 2023 15:39:49 +0530 [thread overview]
Message-ID: <20230412100949.850513-3-b-kapoor@ti.com> (raw)
In-Reply-To: <20230412100949.850513-1-b-kapoor@ti.com>
J784S4 has two instances of 8 channel ADCs in MCU domain. Add pinmux
information for both ADC nodes.
