[PATCH v2 0/3] gpio: Introduce gpio-delay driver and enable it on Kria

[Michal Simek <michal.simek@amd.com>]

Hi,

we need to wait more time for getting USB hub out of reset to be able to do
initialiation over i2c that's why use gpio-delay driver instead of changing
waiting time in usb hub driver. Waiting time depends on gpio wiring on the
board which is in some of our case going via SLG programmable device.

Thanks,
Michal

Changes in v2:
- Check return value from dm_gpio_set_value()
- Do not use GPIOD_IS_OUT when requesting gpio
- fix commit message
