Subject: [media] adv7842: Add pad-level DV timings operations
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c916194cafa2787a42fe3609386f4ed6f65b23a8;p=linux-beck.git

[media] adv7842: Add pad-level DV timings operations

The video enum_dv_timings and dv_timings_cap operations are deprecated.
Implement the pad-level version of those operations to prepare for the
removal of the video version.
