Subject: [PATCH 05/13] arm: dts: s5pv210: aries: Disable pulls on GPIO i2c adapters
Date: Sun, 26 Apr 2020 11:35:56 -0700	[thread overview]
Message-ID: <BN6PR04MB06606817DE468110FE577158A3AE0@BN6PR04MB0660.namprd04.prod.outlook.com> (raw)
In-Reply-To: <20200426183604.28494-1-xc-racer2@live.ca>

The bitbanged GPIO i2c adapters have external pull-ups attached
so the internal pulls should be disabled for lower power usage.
