[PATCH v6 11/13] drm/imx: dc-lb: Drop initial primary and secondary input selections

From: Liu Ying <victor.liu@nxp.com>
Date: 2026-09-04 07:54:50
Also in: dri-devel, imx, linux-arm-kernel, lkml
Subsystem: drm drivers, drm drivers and misc gpu patches, drm drivers for freescale imx8 display controller, the rest · Maintainers: David Airlie, Simona Vetter, Maarten Lankhorst, Maxime Ripard, Thomas Zimmermann, Liu Ying, Linus Torvalds

It's unnecessary to set initial primary and secondary input selections
because KMS driver would do that when doing atomic commits.  Drop the
selections.  This is needed as a preparation for reading LayerBlend
secondary input selection when trying to disable CRTC at boot in an
upcoming commit.
