If error happens in sun8i_dw_hdmi_find_possible_crtcs(), nodes are not released with of_node_put() before returning. Fix that by calling of_node_put() when necessary. While on it, clean up the code by using of_graph_get_remote_node() which also lowers number of cases where error handling has to be performed.

TCON description is expanded with R40 TV TCON compatible. It is a bit special, because it is connected to TCON TOP instead directly to mixer and it needs special handling. Reviewed-by:

R40 has pretty unique display pipeline. It supports two outputs at the same time. Possible outputs: - 1x HDMI, - 2x TV output - 1x VGA, - 1x MIPI DSI and - 2x LCD outputs That is the biggest number of possible outputs from all Allwinner SoC. Because of that, add new compatible for it. Reviewed-by:

When panel power down, p079zca need delay between reset and disable power supply, but p097pfg does not need it. Similarly p097zca needs a delay after entering panel sleep mode. So add two delay properties, so we can meet these two panel power down sequence. Signed-off-by:

Refactor Innolux P079ZCA panel driver, let it support multi panels from Innolux that share similar power sequences. Panels may require different power supplies so use regulator bulk interfaces and define per panel supply-names. Changes in v2: - Change regulator property name to meet the panel datasheet Changes in v3: - this patch only refactor P079ZCA panel to support multi panel, support P097PFG panel in another patch Changes in v4: - Modify the patch which suggest by Thierry Changes in v5: - use regulator_bulk to handle different supply number Signed-off-by:

Having a device with a status property != "okay" in the DT is a valid use case, and we should not prevent the registration of the DRM device when the DSI device connected to the DSI controller is disabled. Consider the ENODEV return code as a valid result and do not expose the DSI encoder/connector when it happens. Signed-off-by:

DT nodes might be present in the DT but with a status property set to "disabled" or "fail". In this case, we should not return -EPROBE_DEFER when the caller asks for a drm_panel instance. Return -ENODEV instead. Signed-off-by:

Boris Brezillon authored
Right now, the DRM panel logic returns NULL when a panel pointing to the passed OF node is not present in the list of registered panels. Most drivers interpret this NULL value as -EPROBE_DEFER, but we are about to modify the semantic of of_drm_find_panel() and let the framework return -ENODEV when the device node we're pointing to has a status property that is not equal to "okay" or "ok". Let's first patch the of_drm_find_panel() implementation to return ERR_PTR(-EPROBE_DEFER) instead of NULL and patch all callers to replace the '!panel' check by an 'IS_ERR(panel)' one. Signed-off-by:

Noralf Trønnes authored
This switches the CMA helper drivers that use its fbdev emulation over to the generic fbdev emulation. It's the first phase of using generic fbdev. A later phase will use DRM client callbacks for the lastclose/hotplug/remove callbacks. There are currently 2 fbdev init/fini functions: - drm_fb_cma_fbdev_init/drm_fb_cma_fbdev_fini - drm_fbdev_cma_init/drm_fbdev_cma_fini This is because the work on generic fbdev came up during a fbdev refactoring and thus wasn't completed. No point in completing that refactoring when drivers will soon move to drm_fb_helper_generic_probe(). tinydrm uses drm_fb_cma_fbdev_init_with_funcs().

Noralf Trønnes authored
This the beginning of an API for in-kernel clients. First out is a way to get a framebuffer backed by a dumb buffer. Only GEM drivers are supported. The original idea of using an exported dma-buf was dropped because it also creates an anonomous file descriptor which doesn't work when the buffer is created from a kernel thread. The easy way out is to use drm_driver.gem_prime_vmap to get the virtual address, which requires a GEM object. This excludes the vmwgfx driver which is the only non-GEM driver apart from the legacy ones. A solution for vmwgfx will have to be worked out later if it wants to support the client API which it probably will when we have a bootsplash client. Suggested-by:
