component schema - miso_pin must be "pins.gpio_input_pin_schema"

[karakum]

just like "spi" component has:

            cv.Optional(CONF_MISO_PIN): pins.gpio_input_pin_schema,
            cv.Optional(CONF_MOSI_PIN): pins.gpio_output_pin_schema,

Your component has both miso & mosi pin schema type pins.gpio_output_pin_schema
