[U-Boot] [PATCH 2/9] ARM: uniphier: split out UMC clock enable
Masahiro Yamada
yamada.masahiro at socionext.com
Sun Jan 15 06:59:03 CET 2017
The clock enable bits for UMC are more SoC-specific than for
the other hardware blocks. Separate the UMC clocks and the other
clocks for better code reuse across SoCs.
