ARM: dts: exynos: Add clocks to audss block to fix silent hang on Exynos4412
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 6edfa11cb396 ("clk: samsung: Add enable/disable operation for PLL36XX clocks"), e.g. on Odroid U3 usually with last (but unrelated) messages: [ 2.382741] input: gpio_keys as /devices/platform/gpio_keys/input/input0 [ 2.405686] usb 1-3: new high-speed USB device number 3 using exynos-ehci [ 2.419843] max77686-rtc max77686-rtc: setting system clock to 2017-06-21 17:04:13 UTC (1498064653) Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
