2020-01-07drm/i915: Add support for non-power-of-2 FB plane alignmentImre Deak
At least one framebuffer plane on TGL - the UV plane of YUV semiplanar FBs - requires a non-power-of-2 alignment, so add support for this. This new alignment restriction applies only to an offset within an FB, so the GEM buffer itself containing the FB must still be power-of-2 aligned. Add a check for this (in practice plane 0, since the plane 0 offset must be 0). v2: - Fix WARN check for alignment=0. v3: - Return error for alignment programming bugs.

2020-01-07drm/vram-helper: Remove BO device from public interfaceThomas Zimmermann
TTM is an implementation detail of the VRAM helpers and therefore shouldn't be exposed to the callers. There's only one correct value for the BO device anyway, which is the one stored in the DRM device. So remove struct ttm_bo_device from the VRAM-helper interface and use the device's VRAM manager unconditionally. The GEM initializer function fails if the VRAM manager has not been initialized.

2020-01-07drm/bridge: Add the necessary bits to support bus format negotiationBoris Brezillon
drm_bridge_state is extended to describe the input and output bus configurations. These bus configurations are exposed through the drm_bus_cfg struct which encodes the configuration of a physical bus between two components in an output pipeline, usually between two bridges, an encoder and a bridge, or a bridge and a connector. The bus configuration is stored in drm_bridge_state separately for the input and output buses, as seen from the point of view of each bridge. The bus configuration of a bridge output is usually identical to the configuration of the next bridge's input, but may differ if the signals are modified between the two bridges, for instance by an inverter on the board. The input and output configurations of a bridge may differ if the bridge modifies the signals internally, for instance by performing format conversion, or*modifying signals polarities. Bus format negotiation is automated by the core, drivers just have to implement the ->atomic_get_{output,input}_bus_fmts() hooks if they want to take part to this negotiation. Negotiation happens in reverse order, starting from the last element of the chain (the one directly connected to the display) up to the first element of the chain (the one connected to the encoder). During this negotiation all supported formats are tested until we find one that works, meaning that the formats array should be in decreasing preference order (assuming the driver has a preference order). Note that the bus format negotiation works even if some elements in the chain don't implement the ->atomic_get_{output,input}_bus_fmts() hooks. In that case, the core advertises only MEDIA_BUS_FMT_FIXED and lets the previous bridge element decide what to do (most of the time, bridge drivers will pick a default bus format or extract this piece of information from somewhere else, like a FW property).

2020-01-06drm/i915: Limit audio CDCLK>=2*BCLK constraint back to GLK onlyKai Vehmanen
Revert changes done in commit f6ec9483091f ("drm/i915: extend audio CDCLK>=2*BCLK constraint to more platforms"). Audio drivers communicate with i915 over HDA bus multiple times during system boot-up and each of these transactions result in matching get_power/put_power calls to i915, and depending on the platform, a modeset change causing visible flicker. GLK is the only platform with minimum CDCLK significantly lower than BCLK, and thus for GLK setting a higher CDCLK is mandatory. For other platforms, minimum CDCLK is close but below 2*BCLK (e.g. on ICL, CDCLK=176.4kHz with BCLK=96kHz). Spec-wise the constraint should be set, but in practise no communication errors have been reported and the downside if set is the flicker observed at boot-time. Revert to old behaviour until better mechanism to manage probe-time clocks is available. The full CDCLK>=2*BCLK constraint is still enforced at pipe enable time in intel_crtc_compute_min_cdclk().

2020-01-05drm/rockchip: lvds: move hardware-specific functions togetherMiquel Raynal
Reorganize a bit the functions order to clarify the driver and separate hardware independent and specific functions a bit. This change only moves functions around, there is no functional change.

2020-01-05drm/rockchip: lvds: improve error handling in helper functionsMiquel Raynal

2020-01-05drm/rockchip: lvds: Create an RK3288 specific probe functionMiquel Raynal
The probe function is highly adapted to the RK3288 specificities, move all specific bits into an "rk3288_probe" function, also part of the platform data. The goal is to ease the addition of new flavors of Rockchip LVDS IPs.

2020-01-05drm/rockchip: lvds: Change platform data to hold helper_funcs pointerMiquel Raynal
Prepare the introduction of PX30 support by using drm_encoder_helper_funcs as platform data instead of multiple register names which are specific to rk3288 and not generic to all Rockchip IPs. This way adding support for a new flavor of a similar IP will be a matter of adding the relevant helper funcs.

2020-01-05drm/rockchip: lvds: Harmonize function namesMiquel Raynal
Prepare the introduction of PX30 support by clarifying the function prefixes. We continue to prefix with 'rockchip_lvds_' generic functions that are not specific to a single hardware. Functions implying hardware modifications are now prefixed with 'rk3288_lvds_'.
