linux-toradex.git/Documentation/ABI/testing/debugfs-iio-backend, branch master Linux kernel for Apalis and Colibri modules iio: backend: add debugFs interface 2024-08-03T13:36:45+00:00 Nuno Sa nuno.sa@analog.com 2024-08-02T14:27:00+00:00 cdf01e0809a4c6c7877ea52401c2a6679df7aed6 This adds a basic debugfs interface for backends. Two new ops are being added: * debugfs_reg_access: Analogous to the core IIO one but for backend devices. * debugfs_print_chan_status: One useful usecase for this one is for testing test tones in a digital interface and "ask" the backend to dump more details on why a test tone might have errors.
