Subject: [PATCH v2 5/6] ARM: configs: at91: sama5: unselect ATMEL_PIT
Date: Fri, 5 Jan 2018 15:30:05 +0100 [thread overview]
Message-ID: <20180105143006.5369-6-alexandre.belloni@free-electrons.com> (raw)
In-Reply-To: <20180105143006.5369-1-alexandre.belloni@free-electrons.com>
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.
