From 2ac00e34acfc93af19376f83bb31db1aea1f006a Mon Sep 17 00:00:00 2001 From: Stefan Mavrodiev Date: Sun, 18 Aug 2019 10:33:41 +0100 Subject: nvmem: sunxi_sid: fix A64 SID controller support Like in H3, A64 SID controller doesn't return correct data when using direct access. It appears that on A64, SID needs 8 bytes of word_size. Workaround is to enable read by registers.
