From: Icenowy Zheng Date: Tue, 24 Oct 2017 09:54:34 +0000 (+0100) Subject: nvmem: sunxi-sid: add support for A64/H5's SID controller X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b7fe57b802c4f12da20920229acb9fff92300ad4;p=linux.git nvmem: sunxi-sid: add support for A64/H5's SID controller Allwinner A64/H5 SoCs come with a SID controller like the one in H3, but without the silicon bug that makes the initial value at 0x200 wrong, so the value at 0x200 can be directly read. Add support for this kind of SID controller.
