From b3316a672bfbedbe0437b21937c1d6aeacbaabe4 Mon Sep 17 00:00:00 2001 From: Chunyan Zhang Date: Fri, 9 Feb 2018 17:55:09 +0800 Subject: clk: sprd: add RTC gate for SC9860 Add a few gate clocks which are used for gating RTC for some devices on AON area of SC9860. This patch has been tested on SC9860, with this patch and proper DT configurations, the watchdog can be initialized and work well.
