Subject: [PATCH v2 03/15] drm/mxsfb: Add defines for the rest of registers
Date: Wed, 14 Aug 2019 13:48:39 +0300
Message-ID: <1565779731-1300-4-git-send-email-robert.chiras@nxp.com> (raw)
In-Reply-To: <1565779731-1300-1-git-send-email-robert.chiras@nxp.com>

Some of the existing registers in this controller are not defined, but
also not used. Add them to the register definitions, so that they can be
easily used in future improvements or fixes.
