Subject: ARM: dts: stm32: add STM32F746 syscfg clock
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=86f15a5a6c13e1f01fd15975274f8e47458c185a;p=users%2Fjedix%2Flinux-maple.git

ARM: dts: stm32: add STM32F746 syscfg clock

The syscfg syscon was missing its clock, therefore any attempt to
read/write it after clk_disable_unused() silently failed. This was
preventing external pin interrupts from working if they were initialized
after this point.
