[PATCH v2] clk: uniphier: add clock drivers for UniPhier SoCs
Masahiro Yamada
yamada.masahiro at socionext.com
Mon Dec 28 02:20:03 PST 2015
This is the initial commit for the UniPhier clock drivers, including
support for PH1-sLD3, PH1-LD4, PH1-Pro4, PH1-sLD8, PH1-Pro5, and
ProXstream2/PH1-LD6b.
To improve the code maintainability, the driver consists of common
functions (clk-uniphier-core.c) and clock data arrays needed to
support each SoC.
Signed-off-by: Masahiro Yamada <yamada.masahiro at socionext.com>
---
Changes in v2:
- split emmc_hw_reset
- make SD clock rate-controllable
- add CLK_SET_RATE_PARENT flag to mux, gate, fixed-factor clocks
