Subject: [PATCH v2 10/10] arm64: dts: actions: Add uSD support for Cubieboard7
Date: Tue, 19 May 2020 23:49:28 +0530	[thread overview]
Message-ID: <1589912368-480-11-git-send-email-amittomer25@gmail.com> (raw)
In-Reply-To: <1589912368-480-1-git-send-email-amittomer25@gmail.com>

This commit adds uSD support for Cubieboard7 board based on Actions Semi
S700 SoC. SD0 is connected to uSD slot. Since there is no PMIC support
added yet, fixed regulator has been used as a regulator node.
