[PATCH 9/9] clk: samsung: Remove obsolete clkdev alias support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Remove support for obsolete clkdev alias definition in generic
helper macros for MUX, DIV, GATE and PLL clocks. clkdev aliases can be
still created using samsung_clk_register_alias() function if given
platform still needs them. All current drivers have been converted
not to use *_A-style macros and checked if there are any clients for
the PLL clocks, which had aliases created unconditionally.
