Merge tag 'remoteproc-for-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/ohad/remoteproc
Pull remoteproc update from Ohad Ben-Cohen: - custom binary format support from Sjur Brændeland - groundwork for recovery and runtime pm support - some cleanups and API simplifications Fix up conflicts in drivers/remoteproc/remoteproc_core.c due to clashes with earlier cleanups by Sjur Brændeland (with part of the cleanups moved into the new remoteproc_elf_loader.c file). * tag 'remoteproc-for-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/ohad/remoteproc: MAINTAINERS: add remoteproc's git remoteproc: Support custom firmware handlers remoteproc: Move Elf related functions to separate file remoteproc: Add function rproc_get_boot_addr remoteproc: Pass struct fw to load_segments and find_rsc_table. remoteproc: adopt the driver core's alloc/add/del/put naming remoteproc: remove the get_by_name/put API remoteproc: support non-iommu carveout assignment remoteproc: simplify unregister/free interfaces remoteproc: remove the now-redundant kref remoteproc: maintain a generic child device for each rproc remoteproc: allocate vrings on demand, free when not needed
