From 4a7d78c27806bc9b90560438e6aef22efd6050fd Mon Sep 17 00:00:00 2001 From: Daniel Machon Date: Mon, 13 Jan 2025 20:36:05 +0100 Subject: [PATCH] net: sparx5: enable FDMA on lan969x In a previous series, we made sure that FDMA was not initialized and started on lan969x. Now that we are going to support it, undo that change. In addition, make sure the chip ID check is only applicable on Sparx5, as this is a check that is only relevant on this platform.
