While there's a common function to parse "memory-region" properties for
DMA pool regions, there's not anything for driver private regions. As a
result, drivers have resorted to parsing "memory-region" properties
themselves repeating the same pattern over and over. To fix this, this
series adds 2 functions to handle those cases:
of_reserved_mem_region_to_resource() and of_reserved_mem_region_count().
I've converted the whole tree, but just including remoteproc here as
it has the most cases. I intend to apply the first 2 patches for 6.15
so the driver conversions can be applied for 6.16.
A git tree with all the drivers converted is here[1].

of: reserved_mem: Add functions to parse "memory-region"
of: Simplify of_dma_set_restricted_buffer() to use
of_for_each_phandle()
remoteproc: Use of_reserved_mem_region_* functions for "memory-region"
