gpiolib: Initializing GPIOs using DT property gpio-initval

Hi,

This is basically a resend with the devicetree mailinglist added to CC.

This series adds a gpio-initval property to the devicetree. It provides a way to initialize GPIOs to a defined value.

There are 3 patches. The first two simplify the function gpiod_hog. The third reuses the gpiod_hog()_code for a new gpiod_initialize() and adds the parsing of the DT.

This series is based on the series
"[PATCH v3 0/9] gpiolib: Add GPIO name support".

Best regards,

Markus

Changes in v2:
- Fixed Signed-off-by/author

Markus Pargmann (3):
gpio: Use __gpiod_request directly
gpiolib: gpiod_hog remove separate name argument
gpiolib: Add GPIO initialization
