From 751963306757e2d90d0d3946862eec38cbadd75b Mon Sep 17 00:00:00 2001 From: Leo Yan Date: Thu, 15 Jun 2017 11:04:10 +0800 Subject: [PATCH] arm64: dts: hi3660: add sp804 timer node The Hi3660 SoC comes with the sp804 timer in addition to the architecture timers. These ones are shutdown when reaching a deep idle states and a backup timer is needed. The sp804 belongs to another power domain and can fulfill the purpose of replacing temporarily an architecture timer when the CPU is idle. Describe it in the device tree, so it can be enabled at boot time.
