From: Finley Xiao Date: Fri, 2 Sep 2016 09:14:26 +0000 (+0100) Subject: nvmem: rockchip-efuse: update compatible strings for Rockchip efuse X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b3149f4e333eb629e0c4c100f337edb0b37cdb79;p=linux-beck.git nvmem: rockchip-efuse: update compatible strings for Rockchip efuse Rk3399-efuse is organized as 32bits by 32 one-time programmable electrical fuses. The efuse of earlier SoCs are organized as 32bits by 8 one-time programmable electrical fuses with random access interface. Add different device tree compatible string for different SoCs to be able to differentiate between the two. The old binding is of course preserved, though deprecated.
