Subject: [PATCH v10 04/23] drm/dsc: Define Rate Control values that do not change over configurations
Date: Tue, 20 Nov 2018 10:37:17 -0800 [thread overview]
Message-ID: <20181120183736.28054-5-manasi.d.navare@intel.com> (raw)
In-Reply-To: <20181120183736.28054-1-manasi.d.navare@intel.com>
From: "Srivatsa, Anusha" <anusha.srivatsa@intel.com>
DSC has some Rate Control values that remain constant
across all configurations. These are as per the DSC
standard.
v3:
* Define them in drm_dsc.h as they are
DSC constants (Manasi)
v2:
* Add DP_DSC_ prefix (Jani Nikula)
