2017-08-15drm: omapdrm: dss: Initialize DSS internal features at probe timeLaurent Pinchart
The DSS internal features are derived from the platform device compatible string which is available at probe time. Don't delay initialization until bind time. This prepares for the merge of the two DSS features structures that will be needed before the DSS is bound.

2017-08-15drm: omapdrm: dss: Use supported outputs instead of display typesLaurent Pinchart
The dss driver uses the supported display types to check whether the DSS has SDI, VENC or HDMI outputs. We can instead use the supported outputs the provide the same information. This removes the last use of the supported display types, that we can then remove as well.

The OMAP implementation of the set_min_bus_tput() API is a no-op. There's no point in forwarding the driver calls to the platform code. Remove the use of the related platform data callback, but keep the internal function as a reminder that the feature will need to be implemented when the OMAP platform will provide support.

2017-08-15drm: omapdrm: dsi: Store DSI model and PLL hardware data in OF dataLaurent Pinchart
The DSI PLL hardware data and DSS channels are selected based on the OMAP SoC model. There's no need for fine-grained model information, as the driver only needs to differentiate between OMAP3, OMAP4 and OMAP5. As this can be done through the DSI compatible string, store the corresponding information in OF match data instead to avoid accessing the OMAP SoC model.

2017-08-15drm: omapdrm: dss: Split operations out of dss_features structureLaurent Pinchart

2017-08-15drm: omapdrm: hdmi: Store PHY features in PHY data structureLaurent Pinchart
PHY features are stored in a global variable, while they should be properties of the PHY object. As existing OMAP platforms have a single HDMI PHY this doesn't cause any issue, but doesn't follow the driver model. Move the PHY features to the HDMI PHY data structure to follow the driver model and pave the road for multiple HDMI PHYs support.

2017-08-15drm: omapdrm: dpi: Remove unneeded regulator checkLaurent Pinchart
The dpi_display_enable() function ensures that a VDDS_DSI regulator is available if the DSI uses the VDDS_DSI supply. This is not needed, as a failure to get the VDDS_DSI supply will result in a probe failure, dpi_display_enable() will thus never be called in that case. Remove the check, and replace tests for the FEAT_DPI_USES_VDDS_DSI feature with a test for the regulator object.
