Subject: [PATCH 5/8] soc: mediatek: mtk-svs: Move SoC specific functions to new files
Date:   Wed, 28 Sep 2022 17:55:16 +0200
Message-Id: <20220928155519.31977-6-matthias.bgg@kernel.org>

From: Matthias Brugger <matthias.bgg@gmail.com>

With every SoC added to the driver, it grows. Move SoC specific
callbacks to a new source files.
