From: Simon Glass Date: Sun, 2 Oct 2016 02:04:51 +0000 (-0600) Subject: rockchip: rk3399: Move rockchip_get_cru() out of the driver X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=c8a6bc968312f572cc84e3928ae5a293f2454849;p=u-boot.git rockchip: rk3399: Move rockchip_get_cru() out of the driver This function is called from outside the driver. It should be placed into common SoC code. Move it. Also rename the driver symbol to be more consistent with the other rockchip clock drivers.
