Subject: [PATCH v2 1/2] ARM: dts: imx7d-sdb: Describe the SD card regulator
Date: Sat, 27 May 2023 13:06:33 -0300	[thread overview]
Message-ID: <20230527160634.345195-1-festevam@gmail.com> (raw)

From: Fabio Estevam <festevam@denx.de>

Improve the devicetree description by adding the SD card regulator
that is controlled via GPIO5_2.
