Subject: [PATCH v2 3/3] misc: fastrpc: add ioctl for attaching to sensors pd
Date: Tue, 8 Sep 2020 09:10:11 -0400 [thread overview]
Message-ID: <20200908131013.19630-4-jonathan@marek.ca> (raw)
In-Reply-To: <20200908131013.19630-1-jonathan@marek.ca>
Initializing sensors requires attaching to pd 2. Add an ioctl for that.
This corresponds to FASTRPC_INIT_ATTACH_SENSORS in the downstream driver.
Signed-off-by: Jonathan Marek <jonathan@marek.ca>
