Subject: [PATCH 6/6] ARM: configs: at91: unselect PIT
|
|
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.18/older/patches-4.18.5-rt3.tar.xz
|
|
|
|
The PIT is not required anymore to successfully boot and may actually harm
|
|
in case preempt-rt is used because the PIT interrupt is shared.
|
|
Disable it so the TCB clocksource is used.
