ARM: stm32: dts: Missing clocks for stm32f429's syscfg.

[PATCH] ARM: stm32: dts: Missing clocks for stm32f429's syscfg.

Posted by Yanjun Yang 1 year, 8 months ago

Without clock definition, SYSCFG will not work, EXTI interrupt for
port other than GPIOA will fail to operate.

Applied on stm32-next.
