2019-02-08drm: rcar-du: Turn LVDS clock output on/off for DPAD0 output on D3/E3Laurent Pinchart3-0/+38
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>
2019-02-08drm: rcar-du: lvds: Add API to enable/disable clock outputLaurent Pinchart4-11/+96
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.

2019-02-08drm: rcar-du: lvds: Don't fail probe if output is not connected on D3/E3Laurent Pinchart1-2/+15
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.

2019-02-08drm: rcar-du: Simplify encoder registrationLaurent Pinchart3-52/+6
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.

2019-02-01drm/i915: Enable fastboot by default on VLV and CHVHans de Goede1-1/+9
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).

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.

2019-01-31drm/i915: Apply LUT validation checks to platforms more accurately (v3)Matt Roper3-32/+40
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.

2019-01-31drm/doc: Drop chapter "KMS Initialization and Cleanup"Daniel Vetter1-96/+0
It only talks about crtc, brings up intel as an example and I think is more misleading than useful really. Plus we have lots of discussion about how your standard kms driver should be initialized/cleaned up, so maybe better to document this when we have a better idea. v2: Fix typo in commit message (Nicholas).

2019-01-30drm/i915: Drop the definite article in front of SAGVVille Syrjälä1-9/+9
The spec doesn't use a definite article in front of SAGV. The rules regarding articles and initialisms are super fuzzy, but at least to my ears it sounds much more natural to not have the article. Perhaps because I tend to pronounce it as "sag-vee" instead of spelling out the letters one at a time. Actually I might still prefer to leave out the article if I did spell them out.

2019-01-30drm/i915: Account for minimum ddb allocation restrictionsVille Syrjälä2-9/+45
On icl+ bspec tells us to calculate a separate minimum ddb allocation from the blocks watermark. Both have to be checked against the actual ddb allocation, but since we do things the other way around we'll just calculat the minimum acceptable ddb allocation by taking the maximum of the two values. We'll also replace the memcmp() with a full trawl over the the watermarks so that it'll ignore the min_ddb_alloc because we can't directly read that out from the hw. I suppose we could reconstruct it from the other values, but I was too lazy to do that now.
