From mboxrd@z Thu Jan 1 00:00:00 1970 From: heiko@sntech.de (Heiko Stuebner) Date: Wed, 30 Sep 2015 21:17:48 +0200 Subject: [PATCH 3/5] ARM: dts: rockchip: add rk3288-popmetal iodomains In-Reply-To: <1443640670-21104-1-git-send-email-heiko@sntech.de> References: <1443640670-21104-1-git-send-email-heiko@sntech.de> Message-ID: <1443640670-21104-4-git-send-email-heiko@sntech.de> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Add the iodomains node and reference the correct regulator for each domain. This also includes adding the currently unused dvp regulators and fixing up two regulators to follow the naming in the schematics.
