Adds a default value for MountMatrix (just an identity matrix) Signed-off-by: Gianni Spadoni <me@gio.blue>
libloading will help us load dylibs, which we need for the libssc / FastRPC implementation Signed-off-by: Gianni Spadoni <me@gio.blue>
This implements support for the Qualcomm Sensor Core (SSC), which provides accel and gyro to some Snapdragon based handhelds made in the past 8 years or so This requires libssc as a runtime dependency, and requires libloading as a build time & runtime dependency As FastRPC devices don't actually show up in a "fastrpc" subsystem, and instead use the "misc" subsystem, some logic has been added to udev/device.rs to check for fastrpc devices and fake the subsystem Signed-off-by: Gianni Spadoni <me@gio.blue>
Based on IIOIMUDevice Signed-off-by: Gianni Spadoni <me@gio.blue>

Makes sure we don't get stuck trying to init the sensor if the subsystem isn't ready Signed-off-by: Gianni Spadoni <me@gio.blue>
Also ups the gyro scaling from 14.0 -> 16.0 Signed-off-by: Gianni Spadoni <me@gio.blue>

This PR adds support for the FastRPC "subsystem" and the Qualcomm Sensor Core
When combined with the correct sensor data and hexagonrpc, this can provide accelerometer & gyroscope support to Snapdragon handhelds that use the SSC for that
Big changes, in no order:
I'm opening this as a draft as I have a couple concerns:
Also, minor naming concern:
Maybe the ssc driver should be split into two, something like:
drivers/ssc/runtime.rs, drivers/ssc/bindings.rsdrivers/ssc_imu/driver.rs, drivers/ssc_imu/event.rsThis is because SSC can provide other sensor data in the future aside from gyro / accel.
Where would I put the
drivers/sscfolder in that case - it seems out of place to have it there if it's just the core SSC stuff?
