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.
