From 32277723ba7e9af0201df2341a3e71ea27605759 Mon Sep 17 00:00:00 2001 From: Finley Xiao Date: Fri, 15 Dec 2017 14:06:08 +0000 Subject: nvmem: rockchip-efuse: parse 'rockchip,efuse-size' The eFuse size is defined in property before, but the length of registers is not equal to the size on some platforms, so we add a new property to redefine it.
