To use a GPIO line for card detection, TMIO_MMC_USE_GPIO_CD is set by a legacy board (arch/sh/boards/mach-ecovec24). For DT platforms, the "cd-gpios" property is a legitimate way for that in case the IP-builtin card detection can not be used for some reason. mmc_of_parse() calls mmc_gpiod_request_cd() to set up ctx->cd_gpio if the "cd-gpios" property is specified. To cater to both cases, mmc_can_gpio_cd() is a correct way to check which card detection logic is used.
