2018-07-03drm: add missing ctx argument to plane transitional helpersRussell King11-13/+19
In commits: 34a2ab5e0689 ("drm: Add acquire ctx parameter to ->update_plane") 1931529448bc ("drm: Add acquire ctx parameter to ->plane_disable") a pointer to a drm_modeset_acquire_ctx structure was added as an argument to the method prototypes. The transitional helpers are supposed to be directly plugged in as implementations of these methods, but doing so generates a warning. Add the missing argument. A number of buggy users were added for drm_plane_helper_disable() which need to be fixed up for this change, which we do by passing a NULL ctx argument.

2018-07-02dma-fence: Allow wait_any_timeout for all fencesDaniel Vetter1-5/+0
When this was introduced in commit a519435a96597d8cd96123246fea4ae5a6c90b02 Author: Christian König <christian.koenig@amd.com> Date: Tue Oct 20 16:34:16 2015 +0200 dma-buf/fence: add fence_wait_any_timeout function v2 there was a restriction added that this only works if the dma-fence uses the dma_fence_default_wait hook. Which works for amdgpu, which is the only caller. Well, until you share some buffers with e.g. i915, then you get an -EINVAL. But there's really no reason for this, because all drivers must support callbacks. The special ->wait hook is only as an optimization; if the driver needs to create a worker thread for an active callback, then it can avoid to do that if it knows that there's a process context available already. So ->wait is just an optimization, just using the logic in dma_fence_default_wait() should work for all drivers. Let's remove this restriction.

2018-07-01drm/pl111: Support Nomadik LCDC variantLinus Walleij6-13/+145
The Nomadik has a variant of the PL110 known as "Color LCD Controller" LCDC. This variant has the same bit ordering as the DRM subsystem (in difference from the other variants) and adds a few bits for the control of 5551, 565 etc in the control register. Notably it also adds a packed RGB888 24BPP mode. We add support by detecting this variant and also adding a small plug-in that will mux the LCDC out if the ASIC happens to be muxed to the other graphics controller (they are mutually exclusive).

2018-06-28console/fbcon: Add support for deferred console takeoverHans de Goede5-8/+154
Currently fbcon claims fbdevs as soon as they are registered and takes over the console as soon as the first fbdev gets registered. This behavior is undesirable in cases where a smooth graphical bootup is desired, in such cases we typically want the contents of the framebuffer (typically a vendor logo) to stay in place as is. The current solution for this problem (on embedded systems) is to not enable fbcon. This commit adds a new FRAMEBUFFER_CONSOLE_DEFERRED_TAKEOVER config option, which when enabled defers fbcon taking over the console from the dummy console until the first text is displayed on the console. Together with the "quiet" kernel commandline option, this allows fbcon to still be used together with a smooth graphical bootup, having it take over the console as soon as e.g. an error message is logged. Note the choice to detect the first console output in the dummycon driver, rather then handling this entirely inside the fbcon code, was made after 2 failed attempts to handle this entirely inside the fbcon code. The fbcon code is woven quite tightly into the console code, making this to only feasible option.

2018-06-27drm/sun4i: Enable DW HDMI PHY clockJernej Skrabec1-1/+6
Current DW HDMI PHY code never prepares and enables PHY clock after it is created. It's just used as it is. This may work in some cases, but it's clearly wrong. Fix it by adding proper calls to enable/disable PHY clock.

A64 HDMI PHY is similar to H3 HDMI PHY except it has two possible PLL clock parents. It is compatible to other HDMI PHYs, like that found in R40.

2018-06-27drm/sun4i: Don't check for panel or bridge on TV TCONsJernej Skrabec1-3/+9
TV TCONs are always connected to TV or HDMI encoder, so it doesn't make sense to check if panel or bridge is connected to them. Check if TCON has channel 0 and only then check for connected panel or bridges.

2018-06-27drm/sun4i: Don't check for LVDS and RGB when TCON has only ch1Jernej Skrabec1-15/+17
LVDS and RGB interfaces are always connected to TCONs which have channel 0. It doesn't make sense to try to init them on TV TCONs.

2018-06-27drm/sun4i: tcon: Generalize engine search algorithmJernej Skrabec1-4/+18
Current "old" method to find engine worked pretty well for DE2. However, it doesn't work when TCON TOP is between mixer (engine) and TCON. TCON TOP has multiple input ports, but current engine search algorithm expects only one. This can be fixed by first looking for output port id and selecting matching input by subtracting 1 for the next round. This work even if there is only one input and output.

2018-06-27drm/sun4i: Don't skip TCONs if they don't have channel 0Jernej Skrabec1-17/+35
TV TCONs (channel 1 only) are always connected to TV or HDMI encoder. Because of that, all output endpoints on such TCON node will point to a encoder which is part of component framework. Correct current graph traversing algorithm in such way that it doesn't skip output enpoints with id 0 on TV TCONs.

2018-06-27drm/sun4i: Add support for traversing graph with TCON TOPJernej Skrabec1-0/+24
TCON TOP is different from other nodes in graph by having 3 input and 3 output ports. Additionally, connection to TV TCON might lead back to HDMI mux input port, creating loops.

2018-06-27drm/sun4i: Split out code for enumerating endpoints in output portJernej Skrabec1-38/+46
Until now, each node has one input port and one output port. However, with TCON TOP this is no longer true. It has 3 input and 3 output ports. In order to prepare to this situation, split out the code which checks all endpoints in input port and adds available components to fifo. This patch doesn't do any functional change.

2018-06-27drm/sun4i: Add TCON TOP driverJernej Skrabec3-1/+341
As already described in DT binding, TCON TOP is responsible for configuring display pipeline. In this initial driver focus is on HDMI pipeline, so TVE and LCD configuration is not implemented. Implemented features: - HDMI source selection - clock driver (TCON and DSI gating) - connecting mixers and TCONS Something similar also existed in previous SoCs, except that it was part of first TCON.

TCON TOP main purpose is to configure whole display pipeline. It determines relationships between mixers and TCONs, selects source TCON for HDMI, muxes LCD and TV encoder GPIO output, selects TV encoder clock source and contains additional TV TCON and DSI gates.
