From 3870b89a810bc7a3e26ec469ee86077c1de6f9b2 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Tue, 28 Feb 2017 11:26:16 +0200 Subject: drm/i915/dsi: Move calling of wait_for_dsi_fifo_empty to mipi_exec_send_packet Instead of calling wait_for_dsi_fifo_empty on all dsi ports after calling a drm_panel_foo helper which calls VBT sequences, move it to the VBT mipi_exec_send_packet helper, which is the one VBT instruction which actually puts data in the fifo. This results in a nice cleanup making it clearer what all the steps on intel_dsi_enable / disable are and this also makes the VBT code properly wait till a command has actually been send before executing the next steps (typically a delay) in the VBT sequence.
