    ARM: tegra: Port tegra to generic clock framework · 92fe58f0
    Prashant Gaikwad authored
    This patch converts tegra clock code to generic clock framework in following way:
     - Implement clk_ops as required by generic clk framework. (tegraXX_clocks.c)
     - Use platform specific struct clk_tegra in clk_ops implementation instead of struct clk.
     - Initialize all clock data statically. (tegraXX_clocks_data.c)
    
    Legacy framework did not have recalc_rate and is_enabled functions. Implemented these functions.
    Removed init function. It's functionality is splitted into recalc_rate and is_enabled.
    
    Static initialization is used since slab is not up in .init_early and clock
    is needed to be initialized before clockevent/clocksource initialization.
    Macros redefined for clk_tegra.
    
    Also, single struct clk_tegra is used for all type of clocks (PLL, peripheral etc.). This
    is to move quickly to generic common clock framework so that other dependent features will
    not be blocked (such as DT binding).
    
    Enabling COMMON_CLOCK config moved to ARCH_TEGRA since it is enabled for both Tegra20
    and Tegra30.
