Drivers that need IRQ_DOMAIN_HIERARCHY should "select" it, but drivers/pinctrl/stm32/Kconfig is the only exception that uses "depends on" syntax. This prevents GPIO drivers from select'ing IRQ_DOMAIN_HIERARCHY.
For example, if I add "select IRQ_DOMAIN_HIERARCHY" to GPIO_XGENE_SB, I get the following recursive dependency error. drivers/gpio/Kconfig:13:error: recursive dependency detected!
