From 394a36dd9dec7fd48b75dab23432632a30f241ea Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Wed, 27 Jan 2021 17:24:42 +0000 Subject: [PATCH] clk: sunxi-ng: Add support for the Allwinner H616 R-CCU The clocks itself are identical to the H6 R-CCU, it's just that the H616 has not all of them implemented (or connected).
