# \[PATCH 06/27\] OMAP: DSS2: Init dispc first before other components - From: Tomi Valkeinen \ - Date: 2011-06-03 10:00:16 - List: linux-fbdev - Page: https://ratatoskr.run/linux-fbdev/2011/06/13461578 - Thread: https://ratatoskr.run/linux-omap/2011/06/13461598/t.md ```text The initialization order of the DSS modules is important when pm_runtime support is implemented. Currently RFBI is initialized before DISPC, which will cause problems with pm_runtime as RFBI uses DISPC. Change the init order so that DISPC is before RFBI.
