[PATCH v7 17/23] drivers: use dev_read_addr_ptr when cast to pointer
Johan Jonker
jbx6244 at gmail.com
Fri Mar 10 17:45:49 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
dev_read_addr_ptr instead of the dev_read_addr function in the
various files in the drivers directory that cast to a pointer.

Changed V6:
use -EINVAL on return
drop cast
Changed V5:
rebase
fix typo
fix more files
