* drm: rcar-du: Skip LVDS1 output on Gen3 when using dual-link LVDS modeLaurent Pinchart2019-06-081-0/+12
| | | | | | | | | | | | | In dual-link LVDS mode, the LVDS1 encoder is used as a companion for LVDS0, and both encoders transmit data from DU0. The LVDS1 output of DU1 can't be used in that case, don't create an encoder and connector for it.

* drm: rcar-du: Support panels connected directly to the DPAD outputsLaurent Pinchart2019-03-281-6/+48
| | | | | | | | | | | | | | | | | The R-Car DU driver assumes that a bridge is always connected to the DU output. This is valid for the LVDS and HDMI outputs, but the DPAD outputs can be connected directly to a panel, in which case no bridge is available. To support this use case, detect whether the entities connected to the DU DPAD outputs are encoders or panels based on the number of ports of their DT node, and retrieve the corresponding type of DRM objects. For panels, additionally create panel bridge instances.

* drm: rcar-du: Turn LVDS clock output on/off for DPAD0 output on D3/E3Laurent Pinchart2019-02-081-0/+1
| | | | | | | | | 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.

* drm: rcar-du: Simplify encoder registrationLaurent Pinchart2019-02-081-2/+1
| | | | | | | | | | 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.

* drm: Split out drm_probe_helper.hDaniel Vetter2019-01-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Having the probe helper stuff (which pretty much everyone needs) in the drm_crtc_helper.h file (which atomic drivers should never need) is confusing. Split them out. To make sure I actually achieved the goal here I went through all drivers. And indeed, all atomic drivers are now free of drm_crtc_helper.h includes. v2: Make it compile. There was so much compile fail on arm drivers that I figured I'll better not include any of the acks on v1. v3: Massive rebase because i915 has lost a lot of drmP.h includes, but not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h there was still one, which this patch largely removes. Which means rolling out lots more includes all over. This will also conflict with ongoing drmP.h cleanup by others I expect. v3: Rebase on top of atomic bochs. v4: Review from Laurent for bridge/rcar/omap/shmob/core bits: - (re)move some of the added includes, use the better include files in other places (all suggested from Laurent adopted unchanged). - sort alphabetically v5: Actually try to sort them, and while at it, sort all the ones I touch. v6: Rebase onto i915 changes. v7: Rebase once more.

* drm: rcar-du: Remove inclusion of drmP.hLaurent Pinchart2019-01-141-1/+0
| | | | | | | | | | | | | | | | | | | The DRM kernel API used to be defined in a handful of headers, pulled in through drmP.h. It has since been split in multiple headers for the different DRM components, and drmP.h turned into a legacy header that just pulls in most of the DRM kernel API (and a large number of other miscellaneous kernel headers). In order to speed up compilation, replace inclusion of drmP.h with only the required headers. It turns out that the rcar-du-drm driver already includes most of the necessary headers, so the change is simple. While at it, remove unneeded inclusion of other headers, and unneeded forward declarations of structures.

* drm: rcar-du: Move CRTC outputs bitmask to private CRTC stateLaurent Pinchart2019-01-141-10/+0
| | | | | | | | | | | | | | | | | | The rcar_du_crtc outputs field stores a bitmask of the outputs driven by the CRTC. This changes based on the configuration requested by userspace, and is used for the sole purpose of configuring the hardware. The field thus belongs to the CRTC state. Move it to the rcar_du_crtc_state structure. As a result the rcar_du_crtc_route_output() function loses most of its purpose. In order to remove it, move dpad0_source calculation to rcar_du_atomic_commit_tail(), until the field gets moved to a state structure. In order to simplify the rcar_du_group_set_routing() implementation, we also store the DPAD1 source in a new dpad1_source field which will move to a state structure with dpad0_source.

| | | | | | | | | | | | | | | | | | The hdmi output in rcar-du uses the i2c slave encoder interface to link to the adv7511 encoder chip. The kms driver creates encoder and connector entities that internally uses the drm_encoder_slave_funcs ops provided by the slave encoder driver. Change the driver such that it expects a bridge entity instead of a slave encoder. The hdmi connector code isn't needed anymore as we expect the adv7511 bridge driver to create/manage the connector. Note that the kms driver still expects a connector node for hdmi to be present in DT. This node has no connection to the connector created by the bridge driver.
