The QBT1000 driver provides an API for communicating with trustzone applications and handles firmware event interrupts. The driver supports the following features: - loading and unloading trustzone applications - sending commands to trustzone applications - voting/un-voting for clocks before/after making a trustzone call - receiving firmware events, signalled by interrupts, and providing them to the driver client - sending a key event in response to firmware finger detect events Change-Id: I1d9d7a6b6bd2d3420a28a8c09868143bb9bd3b27 Signed-off-by: Lior Barenboim <liorb@codeaurora.org>
