From 009e12561369e2fcb992af47001a06f016e9d6b5 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Pawe=C5=82=20Anikiel?= Date: Fri, 5 Apr 2024 14:13:56 +0000 Subject: media: v4l2-subdev: Add pad versions of dv timing subdev calls MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Currently, subdev dv timing calls (i.e. g/s/query_dv_timings) are video ops without a pad argument. This is a problem if the subdevice can have different dv timings for each pad (e.g. a DisplayPort receiver with multiple virtual channels). To solve this, change these calls to include a pad argument, and put them into pad ops. Keep the old ones temporarily to make the switch easier.
