This patch series is partially based on a series Jerome Brunet
submitted about half a year ago. Due to open questions this series never
made it to mainline, see https://patchwork.kernel.org/patch/9384431/
This new attempt uses GPIOLIB_IRQCHIP resulting in less needed code.
Included is also support for using two parent IRQs in case
of IRQ_TYPE_EDGE_BOTH, like in the vendor driver.
The series was successfully tested on a Odroid-C2, e.g. with removing
polling for SD card insertion/removal from the mmc driver.
Changes in v2:
- separate the GPIO IRQ controller from the pinctrl driver
- minor improvements to the GPIO IRQ controller
Changes in v3:
- replace the request_irq based allocation of parent irq's with
chained irq handling, this also fixes the spurious interrupts issue
and allows to remove the workaround code.
Last but not least the parent irq's are no longer visible in
/proc/interrupts.
- minor improvements to the GPIO IRQ controller
Changes in v4:
- separate the gpio-independent interrupt controller part and make
it a driver under drivers/irqchip
Changes in v5:
- smaller changes based on review comments
- split DT patches per ARM / ARM64
