Subject: [PATCH 2/3] ARM: dts: aspeed: zaius: update 12V brick I2C address
Date: Tue, 16 Apr 2019 09:21:50 -0700 [thread overview]
Message-ID: <20190416162150.150154-3-venture@google.com> (raw)
In-Reply-To: <20190416162150.150154-1-venture@google.com>
From: Robert Lippert <rlippert@google.com>
The I2C address of the brick is different depending on the board SKU.
Update the values to instantiate addresses which work for most boards.
