| 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. |
