From 2d22b63f3a5aae2088708941d08cf0f01f430a58 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Thu, 26 Jun 2025 12:04:59 +0200 Subject: [PATCH 4204/5403] drm/mipi-dsi: Add dev_is_mipi_dsi function This will be especially useful for generic panels (like panel-simple) which can take different code path depending on if they are MIPI-DSI devices or platform devices.
