Subject: [PATCH v3 2/2] arm64: dts: ti: k3-j7200-som: Enable I2C
Date: Wed, 19 Apr 2023 09:30:07 +0530	[thread overview]
Message-ID: <20230419040007.3022780-3-u-kumar1@ti.com> (raw)
In-Reply-To: <20230419040007.3022780-1-u-kumar1@ti.com>

This patch enables wkup_i2c0 node in board dts file
along with pin mux and speed.
Also enables underneath eeprom CAV24C256WE.
