Subject: [PATCH v2] ARM: dts: qcom: ipq4019: fix high resolution timer
Date: Sat, 15 Jun 2019 18:29:18 +0200	[thread overview]
Message-ID: <> (raw)

From: Abhishek Sahu <>

Cherry-picked from CAF QSDK repo with Change-Id

Original commit message:
The kernel is failing in switching the timer for high resolution
mode and clock source operates in 10ms resolution. The always-on
property needs to be given for timer device tree node to make
clock source working in 1ns resolution.
