From b8fc9cdb1c5794b4d54ce22aee2ab0b4314abb25 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ond=C5=99ej=20Jirman?= Date: Tue, 10 Mar 2020 06:04:32 +0100 Subject: [PATCH 002/464] clk: sunxi-ng: Don't use CPU PLL gating and CPUX reparenting to HOSC It's not necessary when not using dividers on CPU PLL, and it's causing cntvct jump backs on H3.
