   4 Subject: [PATCH] ARM: dts: qcom: ipq4019: fix high resolution timer
   5
   6 Cherry-picked from CAF QSDK repo.
   7 Original commit message:
   8 The kernel is failing in switching the timer for high resolution
   9 mode and clock source operates in 10ms resolution. The always-on
  10 property needs to be given for timer device tree node to make
  11 clock source working in 1ns resolution.
