[PATCH v8 20/24] drivers: use devfdt_get_addr_index_ptr when cast to pointer

Mon Mar 13 01:32:31 CET 2023


The fdt_addr_t and phys_addr_t size have been decoupled. A 32bit CPU
can expect 64-bit data from the device tree parser, so use
devfdt_get_addr_index_ptr instead of the devfdt_get_addr_index function
in the various files in the drivers directory that cast to a pointer.
As we are there also streamline the error response to -EINVAL on return.

Changed V6:
  use -EINVAL on return
  drop cast
