Subject: [PATCH] gpio: qixis: select CONFIG_REGMAP_MMIO
Date: Thu,  4 Dec 2025 10:48:47 +0100	[thread overview]
Message-ID: <20251204094928.1031494-1-arnd@kernel.org> (raw)

From: Arnd Bergmann <arnd@arndb.de>

The regmap drivers need to be selected by each user, without that there
can be configurations that fail to link:

x86_64-linux-ld: drivers/gpio/gpio-qixis-fpga.o: in function `qixis_cpld_gpio_probe':
gpio-qixis-fpga.c:(.text+0x13a): undefined reference to `__devm_regmap_init_mmio_clk'

Fixes: e88500247dc3 ("gpio: add QIXIS FPGA GPIO controller")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
