Subject: [PATCH 2/4] ARM: dts: aspeed: bletchley: disable GPIOV2 pull-down
Date: Mon, 13 Jun 2022 17:51:48 +0800 [thread overview]
Message-ID: <20220613095150.21917-3-potin.lai.pt@gmail.com> (raw)
In-Reply-To: <20220613095150.21917-1-potin.lai.pt@gmail.com>
The external pull-up cannot drive GPIOV2, so disable GPIOV2 internal
pull-down resistor by the request form HW team.
