The rmi_f11 driver currently disables dribble packets and the palm detect gesture for all devices. This patch creates a parameter in the 2d sensor platform data for controlling this functionality on a per device basis. For more information on dribble packets: Commit 05ba999f ("HID: rmi: disable dribble packets on Synaptics touchpads") For more information on the palm detect gesture: Commit f097deef ("HID: rmi: disable palm detect gesture when present") Signed-off-by:

Commit 5b65c2a0 ("HID: rmi: check sanity of the incoming report") added support for handling incomplete HID reports do to the input data being corrupted in transit. This patch reimplements this functionality in the function drivers so they can handle getting less valid data then they expect. Signed-off-by:

The attn IRQ is related to the chip, rather than the transport, so move all handling of interrupts to the core driver. This also makes sure that there are no races between interrupts and availability of the resources used by the core driver. Signed-off-by:

We have encountered some RMI4 firmwares where there are blank pages in between PDT pages which contain functions. This change makes them correctly enumerate all functions on the device. Tested on S7817 (has empty page 2). Signed-off-by:

The USB control messages require DMA to work. We cannot pass a stack-allocated buffer, as it is not warranted that the stack would be into a DMA enabled area. While here, remove a dead function calling usb_control_msg(). Signed-off-by: -

Instead of sending USB commands for every stats call, collect them once, when status is updated. As the frontend kthread will call it on every few seconds, the stats will still be collected. Besides reducing the amount of USB/I2C transfers, this also warrants that all stats will be collected at the same time, and makes easier to convert it to DVBv5 stats in the future. Signed-off-by: -
