Subject: [PATCH 4/5] clocksource/drivers/imx-tpm: add CLOCK_EVT_FEAT_DYNIRQ
Date: Tue, 14 Dec 2021 20:07:36 +0800	[thread overview]
Message-ID: <20211214120737.1611955-5-peng.fan@oss.nxp.com> (raw)
In-Reply-To: <20211214120737.1611955-1-peng.fan@oss.nxp.com>

From: Peng Fan <peng.fan@nxp.com>

Add CLOCK_EVT_FEAT_DYNIRQ to allow the IRQ could be runtime set affinity
to the cores that needs wake up, otherwise saying core0 has to send
IPI to wakeup core1. With CLOCK_EVT_FEAT_DYNIRQ set, when broadcast
timer could wake up the cores, IPI is not needed.
