The combination of the enable-active-high and enable-at-boot properties
ought be able to cause the driver to do the right thing, the flags do
this:
if (config->enabled_at_boot) {
if (config->enable_high)
cfg.ena_gpio_flags |= GPIOF_OUT_INIT_HIGH;
else
cfg.ena_gpio_flags |= GPIOF_OUT_INIT_LOW;
} else {
if (config->enable_high)
cfg.ena_gpio_flags |= GPIOF_OUT_INIT_LOW;
else
cfg.ena_gpio_flags |= GPIOF_OUT_INIT_HIGH;
}
of_get_named_gpio() just looks up the GPIO number, it doesn't request
the GPIO.
