linux-toradex.git/include/uapi/linux/counter.h, branch v5.17-rc5 Linux kernel for Apalis and Colibri modules counter: Add character device interface 2021-10-17T09:53:52+00:00 William Breathitt Gray vilhelm.gray@gmail.com 2021-09-29T03:15:59+00:00 b6c50affda5957a3629b149a91c7f6688ffce7f7 This patch introduces a character device interface for the Counter subsystem. Device data is exposed through standard character device read operations. Device data is gathered when a Counter event is pushed by the respective Counter device driver. Configuration is handled via ioctl operations on the respective Counter character device node.
