+Subject: [PATCH] ipq40xx: fix high resolution timer
+
+Cherry-picked from CAF QSDK repo.
+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.
