From 2a64b147350f5b28f6b41873fcb453aaebea01c3 Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Thu, 21 Apr 2022 09:31:05 +0200 Subject: [PATCH] drm/display: Move DSC header and helpers into display-helper module DSC is the Display Stream Compression standard for DisplayPort. Move the DSC code into display/ and split the header into files for protocol core and DRM helpers. Adapt all users of the code. No functional changes. To avoid the proliferation of Kconfig options, DSC is part of DRM's support for DisplayPort. If necessary, a new option could make DSC an independent feature.
