Subject: [PATCH 2/2] arm64: dts: marvell: clearfog-gt-8k: set SFP power limit
Date: Sun, 19 May 2019 12:21:06 +0300 [thread overview]
Message-ID: <a79d8f55eab7ed551ea4e052478b04a107e771c1.1558257666.git.baruch@tkos.co.il> (raw)
In-Reply-To: <202cfd4a4c01edef9cbb04fae96d588e115dfeeb.1558257666.git.baruch@tkos.co.il>
The Clearfog GT-8K board is capable of supplying power up to 2A to SFP
modules. Make that explicit in the device-tree. Without this property
current kernel does not allow SFP modules that require more than 1A.
Signed-off-by: Baruch Siach <baruch@tkos.co.il>
