From 0fc21fdf4e1023d0e5f8d42a42cdd372177699e2 Mon Sep 17 00:00:00 2001 From: Alexandre Belloni Date: Wed, 9 Oct 2019 21:48:14 +0200 Subject: ARM: configs: at91: unselect PIT 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.
