    ARM: OMAP: sram: fix BUG in dpll code for !PM case · 63878acf
    Grazvydas Ignotas 提交于
    _omap3_sram_configure_core_dpll is called when SDRC is reprogrammed,
    which is done regardless of CONFIG_PM setting, so we always need it's
    setup code too. Without this, we hit a BUG() on OMAP3 when kernel is
    built without CONFIG_PM:
    
    Reprogramming SDRC clock to 332000000 Hz
