2018-10-23drm/mediatek: fix OF sibling-node lookupJohan Hovold1-2/+3
Use the new of_get_compatible_child() helper to lookup the sibling instead of using of_find_compatible_node(), which searches the entire tree from a given start node and thus can return an unrelated (i.e. non-sibling) node. This also addresses a potential use-after-free (e.g. after probe deferral) as the tree-wide helper drops a reference to its first argument (i.e. the parent device node). While at it, also fix the related cec-node reference leak.

Some platforms may use a single device tree to describe two address spaces, as described in d9f43babb998 ("Documentation: dt: Add bindings for Secure-only devices"). For these platforms it makes sense to define a secure counterpart of /chosen, namely: /secure-chosen. This new node is meant to be used by the secure firmware to pass data to the secure OS.

2018-10-02kbuild: consolidate Devicetree dtb build rulesRob Herring17-101/+48
There is nothing arch specific about building dtb files other than their location under /arch/*/boot/dts/. Keeping each arch aligned is a pain. The dependencies and supported targets are all slightly different. Also, a cross-compiler for each arch is needed, but really the host compiler preprocessor is perfectly fine for building dtbs. Move the build rules to a common location and remove the arch specific ones. This is done in a single step to avoid warnings about overriding rules. The build dependencies had been a mixture of 'scripts' and/or 'prepare'. These pull in several dependencies some of which need a target compiler (specifically devicetable-offsets.h) and aren't needed to build dtbs. All that is really needed is dtc, so adjust the dependencies to only be dtc. This change enables support 'dtbs_install' on some arches which were missing the target.

This move will help enable the 'dtbs' target which builds all the dtbs regardless of kernel config. This transition could break some scripts if they expect dtb files in the old location.
