For socfpga, I get this error when I build for sofpga_defconfig:

drivers/gpio/gpio-pl061.c: In function ‘pl061_irq_handler’:
drivers/gpio/gpio-pl061.c:183:2: error: implicit declaration of function
‘chained_irq_enter’ [-Werror=implicit-function-declaration]
drivers/gpio/gpio-pl061.c:192:2: error: implicit declaration of function
