[OpenWrt-Devel] [PATCH 3/4] ipq40xx: fix high resolution timer

Tue May 14 06:42:19 PDT 2019


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.
