Subject: [PATCH 1/2] arm64: dts: allwinner: h6: add voltage range to OPP table
Date: Fri,  8 May 2020 21:10:34 +0200	[thread overview]
Message-ID: <20200508191035.24276-1-peron.clem@gmail.com> (raw)

Some boards have a fixed regulator and can't reach the voltage set
by the OPP table.

Add a range where the minimal voltage is the target and the maximal
voltage is 1.2V.
