Subject: [PATCH v1 7/9] ARM: dts: gxp: add psu, i2c, gpio
Date:   Tue, 18 Apr 2023 10:28:22 -0500
Message-Id: <20230418152824.110823-8-nick.hawkins@hpe.com>
In-Reply-To: <20230418152824.110823-1-nick.hawkins@hpe.com>
References: <20230418152824.110823-1-nick.hawkins@hpe.com>
Precedence: bulk

From: Nick Hawkins <nick.hawkins@hpe.com>

Add support for the GXP I2C, PSU, and GPIO
