Subject: [PATCH 1/3] ARM: dts: imx6ul-14x14-evk: Add sensors' GPIO regulator
Date: Thu, 24 Oct 2019 16:48:38 +0800 [thread overview]
Message-ID: <1571906920-29966-1-git-send-email-Anson.Huang@nxp.com> (raw)
On i.MX6UL 14x14 EVK board, sensors' power are controlled
by GPIO5_IO02, add GPIO regulator for sensors to manage
their power.
