gpio: pcf857x: select IRQ_DOMAIN
Patch 6e20a0a4 "gpio: pcf857x: enable gpio_to_irq() support" added IRQ domain support to the pcf857x driver, but some configurations (e.g. davinci_all_defconfig) don't already enable CONFIG_IRQ_DOMAIN. Always selecting it from the Kconfig in this case is what other such drivers do as well, and avoids these build errors: Without this patch, building davinci_all_defconfig results in: drivers/gpio/gpio-pcf857x.c: In function 'pcf857x_to_irq': drivers/gpio/gpio-pcf857x.c:167:2: error: implicit declaration of function 'irq_create_mapping' drivers/gpio/gpio-pcf857x.c: In function 'pcf857x_irq_demux_work': drivers/gpio/gpio-pcf857x.c:183:3: error: implicit declaration of function 'irq_find_mapping' drivers/gpio/gpio-pcf857x.c: In function 'pcf857x_irq_domain_cleanup': drivers/gpio/gpio-pcf857x.c:218:3: error: implicit declaration of function 'irq_domain_remove' drivers/gpio/gpio-pcf857x.c: In function 'pcf857x_irq_domain_init': drivers/gpio/gpio-pcf857x.c:230:2: error: implicit declaration of function 'irq_domain_add_linear' Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Cc: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

Say yes here to provide access to most "quasi-bidirectional" I2C
GPIO expanders used for additional digital outputs or inputs.
