Subject: [PATCH v4 05/20] drm/i915/icl: Define PORT_CL_DW_10 register
Date: Thu, 5 Jul 2018 19:19:36 +0530 [thread overview]
Message-ID: <1530798591-2077-6-git-send-email-madhav.chauhan@intel.com> (raw)
In-Reply-To: <1530798591-2077-1-git-send-email-madhav.chauhan@intel.com>
This register used to power down individual lanes for
DDI/DSI ports. Bitfields to power up/down various
combinations of lanes are also added in this patch.
v2: Review comments from Jani N
- Use override instead of "override" for bitfields
- Define mask for override bitfield
- Define PWR_DOWN_LN* macros shifted in place
v3: Correct PWR_DOWN_LN_MASK value (Jani N)
