Subject: [PATCH 2/4] ARM: dts: aspeed: bletchley: disable GPIOV2 pull-down
Date:   Mon, 13 Jun 2022 17:51:48 +0800
Message-Id: <20220613095150.21917-3-potin.lai.pt@gmail.com>
In-Reply-To: <20220613095150.21917-1-potin.lai.pt@gmail.com>
References: <20220613095150.21917-1-potin.lai.pt@gmail.com>
Precedence: bulk

The external pull-up cannot drive GPIOV2, so disable GPIOV2 internal
pull-down resistor by the request form HW team.
