From: Kever Yang Date: Fri, 3 Nov 2017 07:16:12 +0000 (+0800) Subject: rockchip: sysreset: merge into one common driver X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=6ba54058ed6e5b5d7fb14b99a0d9f803ef83b1d3;p=project%2Fbcm63xx%2Fu-boot.git rockchip: sysreset: merge into one common driver Use a common driver for all Rockchip SOC instead of one for each SoC. Use driver_data for reg offset.
