From 1a7ea0280eefd0c0c01dfab8e48e1909b81ba2de Mon Sep 17 00:00:00 2001 From: Raphael Gallais-Pou Date: Thu, 4 Sep 2025 14:53:05 +0200 Subject: [PATCH] ofnode: support panel-timings in ofnode_decode_display_timing The "Display Timings" in panel-common.yaml can be provided by 2 properties - panel-timing: when display panels are restricted to a single resolution the "panel-timing" node expresses the required timings. - display-timings: several resolutions with different timings are supported with several timing subnode of "display-timings" node This patch update the parsing function to handle this 2 possibility when index = 0.
