Subject: [PATCH 8/8] drm/i915: clarify confusion between SDVO and HDMI registers
Date: Mon, 18 Feb 2013 19:00:27 -0300 [thread overview]
Message-ID: <1361224828-3730-9-git-send-email-przanoni@gmail.com> (raw)
In-Reply-To: <1361224828-3730-1-git-send-email-przanoni@gmail.com>
From: Paulo Zanoni <paulo.r.zanoni@intel.com>
Some HDMI registers can be used for SDVO, so saying "HDMIB" should be
the same as saying "SDVOB" for a given HW generation. This was not
true and led to confusions and even a regression.
Previously we had:
- SDVO{B,C} defined as the Gen3+ registers
- HDMI{B,C,D} and PCH_SDVOB defined as the PCH registers
But now:
- SDVO{B,C} became GEN3_SDVO{B,C} on SDVO code
- SDVO{B,C} became GEN4_HDMI{B,C} on HDMI code
- HDMI{B,C,D} became PCH_HDMI{B,C,D}
- PCH_SDVOB is still the same thing
v2: Rebase (v1 was sent in May 2012).
