From 5d4b45a1dd7b00feab57624035dcdbc1bab2e0f8 Mon Sep 17 00:00:00 2001 From: Markus Koch Date: Sun, 21 Jul 2019 20:20:28 +0300 Subject: Input: add support for the FlySky FS-iA6B RC receiver This patch adds support for the FlySky FS-iA6B RC receiver (serial IBUS). It allows the usage of the FlySky FS-i6 and other AFHDS compliant remote controls as a joystick input device. To use it, a patch to inputattach which adds the FS-iA6B as a 115200 baud serial device is required. I will upstream it after this patch is merged.

Let's allow individual drivers specify timestamp in order to provide a more accurate sense of time for the event. It is expected that drivers will set the timestamp in their hard interrupt routine.

This introduces new APIs: - input_setup_polling - input_set_poll_interval - input_set_min_poll_interval - input_set_max_poll_interval These new APIs allow switching an input device into polled mode with sysfs attributes matching drivers using input_polled_dev APIs that will be eventually removed.

Name the field variables after the actual pins on the chip rather than the "reset" and "touch" names from the devicetree bindings that are vaguely inaccurate. No in-tree users pass GPIO numbers in platform data so drop this. Descriptor tables can be used to get these GPIOs from a board file if need be.

This change drop the platform data definition and handling and moves the driver over to generic device properties API. We also drop support for the external clock. If it is needed we will have to extend the bindings to supply the clock reference and handle it properly in the driver. Also, wakeup setting should be coming from I2C client.
