From mboxrd@z Thu Jan 1 00:00:00 1970 From: alexandre.belloni@bootlin.com (Alexandre Belloni) Date: Fri, 23 Feb 2018 18:15:58 +0100 Subject: [PATCH v3 6/6] ARM: configs: at91: unselect PIT In-Reply-To: <20180223171558.7037-1-alexandre.belloni@bootlin.com> References: <20180223171558.7037-1-alexandre.belloni@bootlin.com> Message-ID: <20180223171558.7037-7-alexandre.belloni@bootlin.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
