Subject: [PATCH 1/3] drm/dp: Add DP_DSC_MAX_BPP_DELTA register
Date: Thu, 23 Apr 2026 20:00:33 +0530 [thread overview]
Message-ID: <20260423143035.2267634-2-nemesa.garg@intel.com> (raw)
In-Reply-To: <20260423143035.2267634-1-nemesa.garg@intel.com>
The dsc max bpp delta masks were incorrectly placed
under the DP_DSC_BITS_PER_PIXEL_INC(0x06F) register.
Move these under correct DP_DSC_MAX_BPP_DELTA(0x06E)
register.
v2: Separate patch for correcting register. [Ankit]
