From c127161865bc21a3fc6adad07b38ce8276ba2f8e Mon Sep 17 00:00:00 2001 From: Alexandru Ardelean Date: Mon, 15 Feb 2021 12:40:26 +0200 Subject: docs: ioctl-number.rst: reserve IIO subsystem ioctl() space Currently, only the 'i' 0x90 ioctl() actually exists and is defined in 'include/uapi/linux/iio/events.h'. It's the IIO_GET_EVENT_FD_IOCTL, which is used to retrieve and FD for reading events from an IIO device. We will want to add more ioct() numbers, so with this change the 'i' 0x90-0x9F space is reserved for IIO ioctl() calls.
