[PATCH 6.6 177/244] arm64: dts: mt7986: define 3W max power to both SFP on BPI-R3

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Frank Wunderlich <frank-w@xxxxxxxxxxxxxxx>

commit 6413cbc17f89b3a160f3a6f3fad1232b1678fe40 upstream.

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.
