Merge tag 'devicetree-for-4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull second batch of devicetree updates from Rob Herring: "As Grant mentioned in the first devicetree pull request, here is the 2nd batch of DT changes for 4.1. The main remaining item here is the endianness bindings and related 8250 driver support. - DT endianness specification bindings - big-endian 8250 serial support - DT overlay unittest updates - various DT doc updates - compile fixes for OF_IRQ=n" * tag 'devicetree-for-4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: frv: add io{read,write}{16,32}be functions mn10300: add io{read,write}{16,32}be functions Documentation: DT bindings: add doc for Altera's SoCFPGA platform of: base: improve of_get_next_child() kernel-doc Doc: dt: arch_timer: discourage clock-frequency use of: unittest: overlay: Keep track of created overlays of/fdt: fix allocation size for device node path serial: of_serial: Support big-endian register accesses serial: 8250: Add support for big-endian MMIO accesses of: Document {little,big,native}-endian bindings of/fdt: Add endianness helper function for early init code of: Add helper function to check MMIO register endianness of/fdt: Remove "reg" data prints from early_init_dt_scan_memory of: add vendor prefix for Artesyn of: Add dummy of_irq_to_resource_table() for IRQ_OF=n of: OF_IRQ should depend on IRQ_DOMAIN
