From 5a7b909c7c9a7069fe01c4b3b1f85cfeba82b669 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Wed, 26 May 2021 08:47:06 -0400 Subject: [PATCH] mfd: sec: Drop support for board files and require devicetree The Samsung PMIC drivers since long time are used only on devicetree platforms (Samsung Exynos) and there are no users with board files. Drop the support for board files entirely and depend on OF for matching.
