Subject: fix for rounding errors in cvt/gtf calculation
Date: Wed, 8 Apr 2015 18:39:27 +0530 [thread overview]
Message-ID: <1428498569-6751-1-git-send-email-prladdha@cisco.com> (raw)
While I was testing cvt / gtf timings against the timings given by
standards timing generator spreadsheets, there were differences in
results for some of the formats. Those differences could be traced
back to the rounding used to compute some of the intermediate values.
Following two patches fixes two such rounding errors.
[PATCH 1/2] v4l2-dv-timings: fix rounding error in vsync_bp
[PATCH 2/2] v4l2-dv-timings: fix rounding in hblank and hsync
Please review and share your comments.
Regards,
Prashant
