Convert string compares of DT node names to use of_node_name_eq helper instead. This removes direct access to the node name pointer. For instances using of_node_cmp, this has the side effect of now using case sensitive comparisons. This should not matter for any FDT based system which this is.

Now that the base struct drm_gem_object has a reservation_object, use it and remove the private BO one. We can't use the drm_gem_reservation_object_wait() helper for MSM because (in theory) msm_gem_cpu_prep() will also do some cache maintenance on the GEM object.

Many users of drm_gem_object embed a struct reservation_object into their subclassed struct, so let's add one to struct drm_gem_object. This will allow removing the reservation object from the subclasses and removing the ->gem_prime_res_obj callback. With the addition, add a drm_gem_reservation_object_wait() helper function for drivers to use in wait ioctls.

The Allwinner BSP makes sure that we don't end up with a null start delay or with a delay larger than vtotal. The former condition is likely to happen now with the reworked start delay, so make sure we enforce the same boundaries. Signed-off-by:

Maxime Ripard authored
The current calculation for the video start delay in the current DSI driver is that it is the total vertical size, minus the front porch and sync length, plus 1. This equals to the active vertical size plus the back porch plus 1. That 1 is coming in the Allwinner BSP from an variable that is set to 1. However, if we look at the Allwinner BSP more closely, and especially in the "legacy" code for the display (in drivers/video/sunxi/legacy/), we can see that this variable is actually computed from the porches and the sync minus 10, clamped between 8 and 100. This fixes the start delay symptom we've seen on some panels (vblank timeouts with vertical white stripes at the bottom of the panel). Reviewed-by:

Maxime Ripard authored
The current code allows the TCON clock divider to have a range between 4 and 127 when feeding the DSI controller. The only display supported so far had a display clock rate that ended up using a divider of 4, but testing with other displays show that only 4 seems to be functional. This also aligns with what Allwinner is doing in their BSP, so let's just hardcode that we want a divider of 4 when using the DSI output. Reviewed-by:

Bisected guest kernel changes crashing qemu. Landed at "6c1cd97b drm/virtio: fix resource id handling". Looked again, and noticed we where not only leaking *some* ids, but *all* ids. The old code never ever called virtio_gpu_resource_id_put(). So, commit 6c1cd97b effectively makes the linux kernel starting re-using IDs after releasing them, and apparently virglrenderer can't deal with that. Oops. This patch puts a temporary stopgap into place for the 5.0 release. Signed-off-by:

drm/tegra: Changes for v5.1-rc1 This set of changes starts of with some refactoring of the CEC support to make it reusable on Tegra210 and later. Following are a couple of fixes for HDMI audio support (via HDA). The bulk here is a set of preparatory patches working towards enabling Tegra186 support for host1x and VIC. Additional patches will be needed to fully enable this, but they're not quite ready yet. To round things off, this also adds support for configuring the SOR crossbar using device tree, and fixes a couple of job-related issues in the host1x code. Signed-off-by:

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.

Laurent Pinchart authored
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: -
Laurent Pinchart authored
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.

With the removal of drmP.h from drm_modeset_helper.h the drmP.h are no longer included by any include files in include/drm. The drmP.h file is thus only included explicit either in .c files or in local .h files. This makes the process of deleting the drmP.h includes easier as we have a more local dependency chain. v2: - moved updates of .c files in drm/ to a dedicated patch. This allows the updates to the *.c files to be committed without the removal part. So this patch can wait if it causes build failures due to pending changes Signed-off-by:
