From: Alexandre Belloni Date: Thu, 13 Sep 2018 13:30:24 +0200 Subject: [PATCH 007/342] ARM: configs: at91: unselect PIT Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=b9a3f3c8892299e5539c6ae47a682c3c77e9a3dd 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.
