[U-Boot] [PATCH] dm: Use dev_get_addr() where possible

Simon Glass sjg at chromium.org
Tue Aug 11 16:33:29 CEST 2015


This is a convenient way for a driver to get the hardware address of a
device, when regmap or syscon are not being used. Change existing callers
to use it as an example to others.
