From 3ebc76c424bc0f0768f5c346667e8f51217917ba Mon Sep 17 00:00:00 2001 From: Jerome Brunet Date: Wed, 26 Jun 2024 16:22:08 +0200 Subject: [PATCH] drm/mipi-dsi: add mipi_dsi_usleep_range helper Like for mipi_dsi_msleep(), usleep_range() may often be called in between mipi_dsi_dcs_*() functions and needs a multi compatible counter part.
