Subject: [PATCH] arm64: dts: renesas: Rename numbered regulators
Date: Wed, 11 May 2022 12:24:59 +0200	[thread overview]
Message-ID: <b90dfeb834c4d7dabd22bf03396f33df58f54507.1652264651.git.geert+renesas@glider.be> (raw)

Numbered regulators are prone to conflicts, causing silent overwrites
(see e.g. [1]).

Make conflicts less likely to happen by renaming all numbered regulators
to names reflecting the regulator's purposes.

[1] commit 45f5d5a9e34d3fe4 ("arm64: dts: renesas: r8a77995: draak: Fix
    backlight regulator name").
