DeviceTree updates for 4.17:
- Sync dtc to upstream version v1.4.6-9-gaadd0b65c987. This adds a bunch more warnings (hidden behind W=1). - Build dtc lexer and parser files instead of using shipped versions. - Rework overlay apply API to take an FDT as input and apply overlays in a single step. - Add a phandle lookup cache. This improves boot time by hundreds of msec on systems with large DT. - Add trivial mcp4017/18/19 potentiometers bindings. - Remove VLA stack usage in DT code. -----BEGIN PGP SIGNATURE----- iQItBAABCAAXBQJaxiUdEBxyb2JoQGtlcm5lbC5vcmcACgkQ+vtdtY28YcM0+w/+ L7nkug1Hz2476eRrsn5bm6oOO0vCrhQcDTJ/AlvU1YO8XBVgGEetLDs8drmvD0/O FQDcpumX6G0eFoHTnTNWD7keM+0nY5jZBIAqKQNa9a0HKkjYc4HO5Ot9E02XG8W8 759vvCcGeJpysoCls9u8OplzqiDyNVQJd1a0fLivtafdKypuE/Ywh15wrzckPO+F bxqWQd+uwm98ZVz8/o3vfYtAOJmA06A+hsyVLXYu7iKQcXYVxi+ZNbRV44MQ50NI 1w5m8GgtWe4A2lpXjmeXk1VmLPO3eEgQKnBoH7gcJmCHaVg/SVfMgBscuGSQZRQa rQvaYRUNGJ0Mtji8EZpZb5Vip4ZCDtZCQBB3snN24CvGXI6WuIIg/8ncXt0AfLqn pxFmC32ZcwvJR2NCpPVfTgILm6foT9IzJWKl6SQLVtqqVp9nPFua7T3l8AQak7FB 2MMaaqh7L0l0za0ZgArZZo/IWUHRb0MwZdXAkqBZlQ6f3IBqGQeKCnkclAeH8qYr OorCOmC2OlKXLPHoz8XHeBzPRdnv1dQ//gEkKXBJ2igLU03hRWv9dxnGju/45sun Ifo79uBAUc9s3F4Kjd/zs2iLztuPrYCSICHtJh9LPeOxoV1ZUNt+6Cm23yQ014Uo /GsFW+lzh7c9wB1eETjPHd1WuYXiSrmE4zvbdykyLCk= =ZWpa -----END PGP SIGNATURE----- Merge tag 'devicetree-for-4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux Pull DeviceTree updates from Rob Herring: - Sync dtc to upstream version v1.4.6-9-gaadd0b65c987.
