If you are working on supplemental patches: from the next merge window we will have: + int gpiod_get_array_value_cansleep(unsigned int array_size, + struct gpio_desc **desc_array, + int *value_array); See: https://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio.git/commit/?h=devel&id=eec1d566cdf94b57e8f5ba9fe60eea214929bcfc If your GPIO controller also has .get_multiple() implemented it just becomes one register read if you're lucky. BTW do you have a way upstream for this patch? ARM SoC?
