D1 has a TCON TOP, so its quirks are similar to those for the R40 TCONs. While there are some register changes, the part of the TCON TV supported by the driver matches the R40 quirks, so that quirks structure can be reused. D1 has the first supported TCON LCD with a TCON TOP, so the TCON LCD needs a new quirks structure. D1's TCON LCD hardware supports LVDS; in fact it provides dual-link LVDS from a single TCON. However, it comes with a brand new LVDS PHY. Since this PHY has not been tested, leave out LVDS driver support for now. Signed-off-by:

D1 has a TCON TOP with TCON TV0 and DSI, but no TCON TV1. This puts the DSI clock name at index 1 in clock-output-names. Support this by only incrementing the index for clocks that are actually supported. Signed-off-by:

D1 has a display engine with the usual pair of mixers, albeit with relatively few layers. In fact, D1 appears to be the first SoC to have a mixer without any UI layers. Add support for these new variants. Acked-by:

D1 changes the MMIO offsets for the CSC blocks in the first mixer. The mixers' ccsc property is used as an index into the ccsc_base array. Use an enumeration to describe this index, and add the new set of offsets. Signed-off-by:

D1's mixer 1 has no UI layers, only a single VI layer. That means the mixer can only be used if the primary plane comes from this VI layer. Add the code to handle this case. Signed-off-by:

Newly introduced mode_set callback in engine structure is a much better place for setting mixer output size and interlace mode for the following reasons: 1. Aforementioned properties change only when mode changes, so it's enough to be set only once per mode set. Currently it's done whenever properties of primary plane are changed. 2. It's assumed that primary plane will always cover whole screen. While this is true most of the time, it's not always. DE2/3 planes are universal and mostly equal in functionality. There is no reason to add artificial limitation to primary planes. 3. The current code only works for UI layers, but some mixers do not have any UI layers. Signed-off-by:

This optional callback is useful for setting properties which depends only on current mode. Such properties are width, height and interlaced output. These properties are currently set in update layer callback for primary plane which is less than ideal. More about that in follow up patches, which will migrate that code to this newly defined callback. Signed-off-by:

So far, the binding and driver have relied on the fact that the H6 clocks are both a prefix and a subset of the R40 clocks. This allows them to share the clocks/clock-names items and the clock-output-names order between the hardware variants. However, the D1 hardware has TCON TV0 and DSI, but no TCON TV1. This cannot be supported by the existing scheme because it puts a gap in the middle of the item lists. To prepare for adding D1 support, use separate lists for variants with different combinations of clocks. Reviewed-by:

Move DRM's HMDI helpers into the display/ subdirectoy and add it to DRM's display helpers. Update all affected drivers. No functional changes. The HDMI helpers were implemented in the EDID and connector code, but are actually unrelated. With the move to the display-helper library, we can remove the dependency on drm_edid.{c,h} in some driver's HDMI source files. Several of the HDMI helpers remain in EDID code because both share parts of their implementation internally. With better refractoring of the EDID code, those HDMI helpers could be moved into the display-helper library as well. v3: * fix Kconfig dependencies (Javier) v2: * reduce HDMI helpers to avoid exporting functions (Jani) * fix include statements (Jani, Javier) * update Kconfig symbols Signed-off-by: -

Replace the DP-helper module with a display-helper module. The support for DisplayPort becomes an internal option that drivers have to select. Update all related Kconfig and Makefile rules. Besides the existing code for DisplayPort, the new module will contain helpers for other video-output standards, such as HDMI. Drivers will have to select their required video-output helpers. Linking all display-related code into a single module avoids the proliferation of small kernel modules. The module parameters drm_dp_cec_unregister_delay, dp_aux_i2c_speed_khz, and dp_aux_i2c_transfer_size are moving from the drm_dp_helper namespace to drm_display_helper. v2: * mention module parameters in commit message (Javier) * distiguish between display module and DP support in Kconfig * update Makefile rules for DP helpers * move Kconfig rules into separate file under display/ Signed-off-by:

Once EDID is parsed, the monitor HDMI support information is available through drm_display_info.is_hdmi. This driver calls drm_detect_hdmi_monitor() to receive the same information and stores its own cached value, which is less efficient. Avoid calling drm_detect_hdmi_monitor() and use drm_display_info.is_hdmi instead and also remove sun4i_hdmi.hdmi_monitor as it is no longer necessary. Signed-off-by:
