From: Pavel Kubelun Date: Tue, 14 May 2019 13:42:19 +0000 (+0300) Subject: ipq40xx: fix high resolution timer X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=e00e6fa90e65beaaa395070fe4d71b298fb01576;p=openwrt%2Fstaging%2Fluka.git ipq40xx: fix high resolution timer Cherry-picked from CAF QSDK repo. see 090-ipq40xx-fix-high-resolution-timer.patch 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.
