Subject: [PATCH v2] ARM: dts: qcom: ipq4019: fix high resolution timer
From: Abhishek Sahu <absahu@...eaurora.org>
Cherry-picked from CAF QSDK repo with Change-Id
I7c00b3c74d97c2a30ac9f05e18b511a0550fd459.
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.
