Subject: [PATCH v1 1/3] arm64: dts: mt7986: define 3W max power to both SFP on BPI-R3
Date: Sun, 20 Aug 2023 17:31:33 +0200	[thread overview]
Message-ID: <20230820153135.42588-2-linux@fw-web.de> (raw)
In-Reply-To: <20230820153135.42588-1-linux@fw-web.de>

From: Frank Wunderlich <frank-w@public-files.de>

All SFP power supplies are connected to the system VDD33 which is 3v3/8A.
Set 3A per SFP slot to allow SFPs work which need more power than the
default 1W.
