[PATCH 4/8] net: fsl-mc: sync DPRC MC APIs
Ioana Ciornei
ioana.ciornei at nxp.com
Wed May 31 18:04:32 CEST 2023
Sync the Data Resource Container APIs to their latest form, this means
the layout of each command is created based on structures which clearly
describe the endianness of each field rather than some macros.
The command version is kept in place, meaning that the minimum MC
version accepted is not changed in any way.
