2017-06-02drm/omap: use DRM_FORMAT_* instead of OMAP_DSS_COLOR_*Tomi Valkeinen3-144/+132
This patch changes omapdrm to use DRM_FORMAT_* values instead of OMAP_DSS_COLOR_* enum. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

2017-06-02drm/omap: change supported_modes to an arrayTomi Valkeinen4-68/+91
enum omap_color_mode is a bitmask, so at the moment we present the supported color modes as mask. To be able to move to fourccs, we need to use an array to present the supported color modes. As a first step towards fourccs, this patch changes the code to use an array to store the enums.

2017-06-02drm/omap: remove dma & vrfb rotationTomi Valkeinen4-263/+8
We have three rotation methods supported by the SoCs with DSS: DMA, VRFB and TILER. DMA rotation works in theory on all DSS platforms, but in practice it's unusable due to the huge amount of memory bandwidth it uses, and has never really been used. VRFB is available on OMAP3, but is not supported by omapdrm, even though we have some code for it in the dispc driver. TILER is supported on OMAP4/OMAP5/DRA7/AM5 platforms, but has some driver bugs. To clean up the driver to help fixing the TILER issues, this patch drops the DMA and VRFB rotation support, leaving only TILER rotation.

2017-06-02drm/omap: remove CLUTTomi Valkeinen3-65/+2
DSS IP versions 2 and 3 support CLUT modes (color lookup table), but the driver has never supported those. We still have had some code for CLUT modes. As the newer DSS IP versions have dropped CLUT support, we might as well clean up the driver by removing the CLUT related code.

2017-06-02drm/omap: fix setting & clearing DOUBLESTRIDETomi Valkeinen1-5/+6
The code that sets and clears DOUBLESTRIDE is only ran when using NV12. This is not correct, as we might first set the bith when using NV12, but never clear it when using other formats. Fix it so that when the bit is available (when the HW supports NV12) we always either set or clear the bit.

There's still a couple of custom helpers left, but the driver needs more extensive changes to get rid of them.

2017-04-03drm/omap: fix replication logicTomi Valkeinen2-5/+5
DSS uses "replication logic" to convert color components from smaller bit widths to bigger bit widths. Without replication logic, the color component would be shifted and the least significant bits would be left at 0, whereas with replication logic, the least significat bits will be filled with the most significant bit. For some reason omapdrm leaves replication logic always to off, which, in the most common case, means that showing 16-bit RGB colors on 24-bit display gives a bit darker colors than expected. The reset value of the replication logic bit is enabled, and it should always be set, as there's no practical reason to disable it. This patch removes the option to disable it from omapdrm, and always sets it to enabled in dispc.

2017-04-03drm/omap: move dispc related dss-feat funcs to dispcTomi Valkeinen4-3/+27
omapdrm still uses a few non-dispc functions: dss_feat_get_num_mgrs(), dss_feat_get_num_ovls() and dss_feat_get_supported_color_modes(). We want to provide omapdrm a single dispc_ops function pointer struct so that omapdrm will use either the current omapdss or the new omapdss6 driver depending on the platform. Those three functions are really dispc functions, but are located in the dss_features.c for legacy reasons.

2017-04-03drm/omap: fix HDMI sync polaritiesTomi Valkeinen1-5/+7
While implementing writeback support, odd behavior of WBDELAYCOUNT was observed with the combination of WB capture and HDMI. The result of the debugging was that the HDMI sync polarities are not set correctly. The current code sets the sync polarities going from HDMI WP to DISPC according to the video mode used, which seems to work normally fine, but causes problems with WB as WB expects the syncs to be active-high.
