The OMAP4 and OMAP5 PLLs have different properties that require specific handling in the HDMI PLL driver. This needs knowledge of the PLL version, which is currently inferred from the DSS version. AS part of the effort to remove usage of the DSS version, use the HDMI controller version instead. Signed-off-by:

The HDMI audio driver only needs to know which generation of HDMI transmitter it deals with, not the detailed SoC model. Pass the version number as an integer to prepare for removal of the OMAP SoC version from the omapdrm driver. Signed-off-by:

The HDMI wrapper code only needs to differentiate between major OMAP revisions, which can be obtained from the HDMI transmitter compatible string. Replace the OMAP SoC model checks to prepare for removal of the OMAP SoC version platform data. Signed-off-by:

The dsi_pll_ops structure and dsi_init_pll_data() function incorrectly use a dsi_ prefix, likely due to copy & paste. Fix it by using the correct hdmi_ prefix. Signed-off-by:

We are missing OMAP5 DSIPHY lane-enable support, which has prevented OMAP5 DSI working in mainline. This patch adds the lane-enable similarly to the recently added OMAP4 version. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

Use the compatible string instead of the OMAP SoC revision to determine device features. The various OMAP3-based SoCs can't be told apart using the compatible string, use soc_device_match() to tell them apart. Signed-off-by:

Use the compatible string instead of the OMAP SoC revision to determine device features. On OMAP34xx the features depend on the ES revision that can not be determined from the compatible string. Use soc_device_match() in that case. Signed-off-by:

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.

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. Signed-off-by:

Move the two function pointers to a new dss_ops structure. This will allow merging the dss_features and omap_dss_features structures without having to expose the DPI source selection and LCD clock muxing functions in header files. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:
