Subject: [PATCH 0/7] Add lspcon support
Date: Tue, 22 Mar 2016 19:55:01 +0530 [thread overview]
Message-ID: <1458656708-31228-1-git-send-email-shashank.sharma@intel.com> (raw)
LSPCON is essentially an active DP-HDMI convertor. It has
two modes of operations:
- ls mode (for upto HDMI 1.4 outputs, 4k@30 resoution / 297MHz)
- pcon mode (for upto HDMI 2.0 outputs, 4k@60 resolution / 600 MHz)
This patch set adds support for LS mode of operation for GEN9
platforms. It adds a new connector for lspcon, whcih is a mix
and match of DP and HDMI connectors, matching dual personality
of lspcon devices.
Notes:
- Daniel Vetter gave a review comment on LSPCON design, to make
it a separate encoder. This patch set tries to match that expectations
with a separate connector, as DDI encoder already fulfills all the
requirements of a lspcon_encoder.
- This patch set tagrets LS mode of operations only.
- PCON mode of operation will be added later, based on the requirements.
This is to primarily unbloc Linux devices with LSPCON port.
- This patch set is tested with BXT RVP + drm-nightly
- As we redesigned this code, to meet the review comments, this is a working
patch set, but not upto commercial quality yet.
