Subject: [PATCH v2 08/18] ARM: dts: s5pv210: Add touchkey support to aries boards
Date: Fri,  1 May 2020 16:50:09 -0700	[thread overview]
Message-ID: <BN6PR04MB066049CF813A339C7AFA8FB7A3AB0@BN6PR04MB0660.namprd04.prod.outlook.com> (raw)
In-Reply-To: <20200501235019.24022-1-xc-racer2@live.ca>

Aries boards have soft touchkeys, manufactured by Cypress,
attached over i2c-gpio.
