From 2be9ff2d65e968497e04e3cd66ccbf9178252493 Mon Sep 17 00:00:00 2001 From: Andrew Turner Date: Tue, 26 Jan 2021 21:58:16 +0000 Subject: [PATCH] Remove old Marvell drivers These have probe functions that can only match device tree files that have been removed because the boards they describe are unsupported.
