[U-Boot] [PATCH 06/16] ARM: uniphier: clean up UMC init for PXs2 SoC
Masahiro Yamada
yamada.masahiro at socionext.com
Fri Jan 27 22:53:46 CET 2017
Just cosmetic changes:
- Rename prefix DMPHY_ to MPHY_ for consistency
- Move UMC parameters below for complete decouple of PHY and UMC
- Remove redundant whitespaces
