From f65a73f3c8fd3f4d1ca51f537b97b97eaab59bf6 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Fri, 2 Jun 2023 08:40:16 +0300 Subject: libcamera: controls: Drop reference to IPA in controls documentation The controls relates to the public API, which doesn't expose IPA modules as they are internal to libcamera. Replace the mention of "IPA" in the controls documentation. While at it, fix a small text reflow issue.
