From f2b0e264657061667be7df1575b82777cf622b73 Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Mon, 1 Oct 2018 14:38:40 +0200 Subject: drm/bridge/synopsys: dsi: don't call __dw_mipi_dsi_probe from dw_mipi_dsi_bind __dw_mipi_dsi_probe() does all the grabbing of resources and does it using devm-helpers. So this is happening on each try of master bringup possibly slowing down things a lot. Drivers using the component framework may instead want to call dw_mipi_dsi_probe separately in their probe function to setup resources early. That way the dsi bus also gets created earlier and also not recreated on each bind-try, so that attached panels can load their modules and be probed way before the bridge-attach in the bind call. So drop the call to __dw_mipi_dsi_probe and modify the function to take a struct dw_mipi_dsi instead of the platform-device.
