From 8e2aeb5b128e4a90fdd7b27ad3740a4b07284333 Mon Sep 17 00:00:00 2001 From: Chih-En Hsu Date: Thu, 17 Sep 2020 14:44:34 +0100 Subject: nvmem: mtk-efuse: Remove EFUSE register write support This patch is to remove function "mtk_reg_write" since Mediatek EFUSE hardware only supports read functionality for NVMEM consumers.
