Subject: [PATCH 1/5] i3c: master: svc: enable hotjoin default
Date: Mon, 16 Oct 2023 11:46:28 -0400	[thread overview]
Message-ID: <20231016154632.2851957-2-Frank.Li@nxp.com> (raw)
In-Reply-To: <20231016154632.2851957-1-Frank.Li@nxp.com>

Hotjoin require clock running and enable SLVSTART irq.
Add module parameter 'hotjoin' to disable hotjoin and enable runtime_pm to
save power.
