RE: Status of RMI4 drivers?

Hi Kristina,

Once again, my apologies for top-posting.

The synaptics-rmi4 driver is intended to work with any RMI4 compliant sensors (subject to platform specific tweaks), and this should handle any of the sensors currently handled by the staging drivers or other drivers based off of the staging code.

Good to know, thanks. So what happens to the staging drivers once you
merge the driver? Will their devices be supported by the new driver or
will someone have to merge their functionality into the new driver (and
test it)?
