    ARM: dts: exynos: Add clocks to audss block to fix silent hang on Exynos4412 · a3c0d2fb
    Krzysztof Kozlowski 提交于
    Add necessary parent clocks for audss (Audio SubSystem, MAUDIO) clock
    controller block.
    
    This allows driver to keep EPLL enabled before accessing any MAUDIO
    registers thus fixing silent hang.  This silent hang appeared with
    commit 6edfa11c ("clk: samsung: Add enable/disable operation for
    PLL36XX clocks"), e.g. on Odroid U3 usually with last (but unrelated)
