…der value Frame rate selected by the user may not be obtained due to PCLK frequency and finite number of clock divider values. In such case, driver shall select divider that results in frame clock rate closest to the requested value. There was a bug that was discarding perfect match divider. Add test which confirms correct clock divider selection. Upstream PR #: 90720 Signed-off-by: Sebastian Głąb <sebastian.glab@nordicsemi.no>
