Subject: [PATCH 3/8] arm64: dts: ti: k3-j784s4-evm: Enable wakeup_i2c0 and eeprom
Date: Fri, 2 Jun 2023 16:49:32 -0500	[thread overview]
Message-ID: <20230602214937.2349545-4-nm@ti.com> (raw)
In-Reply-To: <20230602214937.2349545-1-nm@ti.com>

Enable wakeup_i2c and use un-used pinmux. While at it, describe the
board detection eeprom present on the board.
