[PATCH 0/4] gpio: select GPIOLIB_IRQCHIP for various entries

[Peng Fan (OSS)]

There was an effort to make irq_chip immutable for several drivers,
but kernel test robot reports build errors for:
gpio-mpc8xxx
gpio-pxa
gpio-davinci

Thanks to Bartosz for helping on this.

To avoid potential build failure with random config, select
GPIOLIB_IRQCHIP for bcm-kona, grgpio, lpc18xx, timberdale.

Build pass with:
 for i in `ls arch/arm/configs`
 do
 echo $i
 make ARCH=arm $i
 make ARCH=arm zImage -j32  > /dev/null
 done

And build with arm64 defconfig.

Hope all is good now.

[PATCH 1/4] gpio: bcm-kona: select GPIOLIB_IRQCHIP

[Peng Fan (OSS)]

From: Peng Fan <peng.fan@nxp.com>

This driver uses gpiochip_irq_reqres() and gpiochip_irq_relres() which
are only built with GPIOLIB_IRQCHIP=y. Add the missing Kconfig select.
