From e24328974a88aa8541e94e8bb8dfa2ade1b3c45d Mon Sep 17 00:00:00 2001 From: Donggeun Yoo Date: Wed, 2 Sep 2026 00:21:26 +0900 Subject: iio: proximity: vl53l0x-i2c: claim direct mode for raw reads vl53l0x_read_raw() starts a single-shot ranging measurement and reads back the result. Once the triggered buffer is enabled the sensor runs in continuous mode and its data-ready interrupt is routed to the trigger, so a concurrent in_distance_raw read disturbs the streaming setup and never gets its completion, returning -ETIMEDOUT. The original submission claimed direct mode here, but it was dropped during review because the driver had no buffer support at the time [1]. Continuous (buffered) mode was later added without restoring the claim [2], reintroducing the conflict. Reject direct reads while buffered capture is active by claiming direct mode around the measurement, as the vl53l1x sibling already does.

We have +repeatedly found them to be detrimental to Linux users, businesses, and +the greater Linux ecosystem. Such modules negate the openness, +stability, flexibility, and maintainability of the Linux development +model and shut their users off from the expertise of the Linux +community. Vendors that provide closed-source kernel modules force their +customers to give up key Linux advantages or choose new vendors. +Therefore, in order to take full advantage of the cost savings and +shared support benefits open source has to offer, we urge vendors to +adopt a policy of supporting their customers on Linux with open-source +kernel code. + +We speak only for ourselves, and not for any company we might work for +today, have in the past, or will in the future. + + - Dave Airlie + - Nick Andrew + - Jens Axboe + - Ralf Baechle + - Felipe Balbi + - Ohad Ben-Cohen + - Muli Ben-Yehuda + - Jiri Benc + - Arnd Bergmann + - Thomas Bogendoerfer + - Vitaly Bordug + - James Bottomley + - Josh Boyer + - Neil Brown + - Mark Brown + - David Brownell + - Michael Buesch + - Franck Bui-Huu + - Adrian Bunk + - François Cami + - Ralph Campbell + - Luiz Fernando N.
