1/2 touches pinctrl driver, but
I want both patches in GPIO tree
because 1/2 is a prerequisite for 2/2.
Otherwise, Kconfig reports recursive dependency.
I noticed this problem when I added "select IRQ_DOMAIN_HIERARCHY"
to my GPIO driver, which I will submit later.
Please apply 1/2 to GPIO tree, not pinctrl tree.

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!

This driver calls irq_domain_hierarchy() and irq_chip_*_parent().
They are available only when CONFIG_IRQ_DOMAIN_HIERARCHY is enabled.

This driver supports the GPIO block within the APM X-Gene
Standby Domain. Say yes here to enable the GPIO functionality.
