From 46678fbdca914c1de61a87357337eb680c4c4512 Mon Sep 17 00:00:00 2001 From: Russell King Date: Wed, 27 Nov 2019 11:45:35 +0000 Subject: [PATCH] mvebu: add uDPU update patches Update the uDPU kernel support, fixing a number of issues: * make ethernet work again by adding comphy definitions * slow the I2C bus to give it more chance of actually working * the SFP cages are designed to support up to 3W modules, which would be prevented from initialising without this patch.
