Subject: [PATCH 6/6] regulator: pf8x00: use linear range for buck 1-6
Date: Tue, 15 Dec 2020 21:48:58 +0100	[thread overview]
Message-ID: <20201215204858.8186-7-adrien.grassein@gmail.com> (raw)
In-Reply-To: <20201215204858.8186-1-adrien.grassein@gmail.com>

Use a linear range to describe the voltages of the
bucks 1-6 instead of listing it one by one (via a macro)
