2018-07-11drm/sun4i: tcon-top: Add helpers for mux switchingJernej Skrabec
We want to be able to set TCON TOP muxes at runtime. Add helpers for that. Old, static configuration of muxes at probe time is preserved for now. It will be removed when R40 TCON starts using them.

2018-07-11drm/sun4i: DW HDMI: Release nodes if error happens during CRTC searchJernej Skrabec
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.

2018-07-10x86/gpu: reserve ICL's graphics stolen memoryPaulo Zanoni
ICL changes the registers and addresses to 64 bits. I also briefly looked at implementing an u64 version of the PCI config read functions, but I concluded this wouldn't be trivial, so it's not worth doing it for a single user that can't have any racing problems while reading the register in two separate operations. v2: - Scrub the development (non-public) changelog (Joonas). - Remove the i915.ko bits so this can be easily backported in order to properly avoid stolen memory even on machines without i915.ko (Joonas). - CC stable for the reasons above.

2018-07-10drm/ttm: Introduce ttm_bo_get() and ttm_bo_put() for ref countingThomas Zimmermann
The TTM buffer-object interface provides ttm_bo_reference() and ttm_bo_unref() for managing reference counts. Replacing them with ttm_bo_get() and ttm_bo_put() aligns the API with conventions used throughout the Linux kernel. The implementation of ttm_bo_unref() clears the supplied pointer to NULL. This leads to workarounds where the caller saves the pointer's value before de-referencing the BO. ttm_bo_put() does not clear the supplied pointer.

2018-07-10drm/vc4: Support the case where the DSI device is disabledBoris Brezillon
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.

2018-07-10drm/of: Make drm_of_find_panel_or_bridge() fail when the device is disabledBoris Brezillon
There's no point searching for a drm_bridge or drm_panel if the OF node we're pointing has a status property that is not "okay" or "ok". Just return -ENODEV in this case.

2018-07-10drm/panel: Let of_drm_find_panel() return -ENODEV when the panel is disabledBoris Brezillon
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.
