On the D3 and E3 SoCs the LVDS PLL clock output provides the dot clock to the DU channels, even when the LVDS outputs are not in use. Enable and disable the LVDS clock output when enabling or disabling a CRTC connected to the DPAD0 output. Signed-off-by:Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

On the D3 and E3 platforms, the LVDS internal PLL supplies the pixel clock to the DU. This works automatically for LVDS outputs as the LVDS encoder is enabled through the bridge API, enabling the internal PLL and clock output. However, when using the DU DPAD output with the LVDS outputs turned off, the LVDS PLL needs to be controlled manually. Add an API to do so, to be called by the DU driver. The drivers/gpu/drm/rcar-du/ directory has to be treated as obj-y unconditionally, as the LVDS driver could be built-in while the DU driver is compiled as a module. Signed-off-by: -

On the D3 and E3 SoCs the LVDS encoder has an extended internal PLL and supplies a clock to the DU. That clock is used not only for the LVDS outputs but also for the DPAD output. The LVDS encoder thus needs to be available to the DU even when its output is disabled. Don't fail probe in that case on D3 and E3. Signed-off-by: -

Before the driver fully moved to drm_bridge and drm_panel, it was necessary to parse DT and locate encoder and connector nodes. The connector node is now unused and can be removed as a parameter to rcar_du_encoder_init(). As a consequence rcar_du_encoders_init_one() can be greatly simplified, removing most of the DT parsing.

We really want to have fastboot enabled by default to avoid an ugly modeset during boot. Currently we are enabling fastboot by default on gen9+ (Skylake and newer). The intention is to enable it on older generations after it has seen more testing on gen9+. VLV and CHV devices are still being sold in stores today, as such it is desirable to also enable fastboot by default on these now. I've extensively tested fastboot=1 support on over 50 different Bay- and Cherry-Trail devices. Testing DSI and eDP panels as well as HDMI output (and even DP over Type-C on one device). All 50 devices work fine with fastboot=1. On 2 devices their DSI panel turns black as soon as the i915 driver loads when fastboot=0, so having fastboot enabled is required for these 2 to work properly (for lack of a better fix).

Enables blend optimization for floating point RTs This restores the workaround that was reverted in c358514b ("Revert "drm/i915/icl: WaEnableFloatBlendOptimization""). The revert was due to the register write seemingly not sticking, but the HW team has confirmed that this is because the register is WO and that the workaround is indeed required. Here the wa is added with a mask of 0 since the register is WO.

We can't safely probe Type C ports, whether they are a legacy or a USB/Thunderbolt DP Alternate Type C port. This would require performing the TypeC connect sequence - as described by the specification - but that may have unwanted side-effects. These side-effects include at least - without completeness - timeouts during AUX power well enabling and subsequent PLL enabling errors. To safely identify these ports we really need VBT, which has the proper flag for this (ddi_vbt_port_info::supports_typec_usb, supports_tbt). Based on the above disable Type C ports if we can't load VBT for some reason. v2: - Notice that we disable TypeC ports completely and simplify accordingly (Jose). - Add code comment explaining why we disabled the ports.

commit 5b0bd14d ("drm/i915/icl: keep track of unused pll while looping") inadvertently (I presume) changed the code to pick the last unused dpll rather than the first unused one like we did before. While there should most likely be no harm in changing the order let's change back just to avoid a change in the behaviour. At least it might reduce the confusion when staring at logs (took me a while to figure out why DPLL1 being picked over DPLL0 when the latter was most definitely available).

Use of the new DRM_COLOR_LUT_NON_DECREASING test was a bit over-zealous; it doesn't actually need to be applied to the degamma on "bdw-style" platforms. Likewise, we overlooked the fact that CHV should have that test applied to the gamma LUT as well as the degamma LUT. Rather than adding more complicated platform checking to intel_color_check(), let's just store the appropriate set of LUT validation flags for each platform in the intel_device_info structure. v2: - Shuffle around LUT size tests so that the hardware-specific tests won't be applied to legacy gamma tables. (Ville) - Add a debug message so that it will be easier to understand why an atomic transaction involving incorrectly-sized LUT's got rejected by the driver. v3: - Switch size_t's to int's.
