Srinivas Pandruvada 138bc7969c iio: hid-sensor-hub: Implement batch mode ... HID sensor hubs using Integrated Senor Hub (ISH) has added capability to support batch mode. This allows host processor to go to sleep for extended duration, while the sensor hub is storing samples in its internal buffers. 'Commit f4f4673b75 ("iio: add support for hardware fifo")' implements feature in IIO core to implement such feature. This feature is used in bmc150-accel-core.c to implement batch mode. This implementation allows software device buffer watermark to be used as a hint to adjust hardware FIFO. But HID sensor hubs don't allow to change internal buffer size of FIFOs. Instead an additional usage id to set "maximum report latency" is defined. This allows host to go to sleep upto this latency period without getting any report. Since there is no ABI to set this latency, a new attribute "hwfifo_timeout" is added so that user mode can specify a latency. This change checks presence of usage id to get/set maximum report latency and if present, it will expose hwfifo_timeout.
