From: Jernej Skrabec Date: Mon, 11 Jan 2021 20:11:40 +0000 (+0100) Subject: sunxi: introduce support for H616 clocks X-Git-Url: http://git.dujemihanovic.xyz/img/sics.gif?a=commitdiff_plain;h=b18bd53d6cde6cd458f279a667eaaf6082c1af45;p=u-boot.git sunxi: introduce support for H616 clocks H616 has mostly the same clocks as H6 with some small differences. Just reuse H6 clocks for H616 and handle differences with macros.
