Subject: [PATCH net v2] powerpc: dts: t208x: Disable 10G on MAC1 and MAC2
Date: Fri, 16 Dec 2022 12:29:37 -0500	[thread overview]
Message-ID: <20221216172937.2960054-1-sean.anderson@seco.com> (raw)

There aren't enough resources to run these ports at 10G speeds. Disable
10G for these ports, reverting to the previous speed.

Fixes: 36926a7d70c2 ("powerpc: dts: t208x: Mark MAC1 and MAC2 as 10G")
Reported-by: Camelia Alexandra Groza <camelia.groza@nxp.com>
Signed-off-by: Sean Anderson <sean.anderson@seco.com>
---

Changes in v2:
- Remove the 10g properties, instead of removing the MAC dtsis.
