[PATCH 0/3] gpiolib: Initializing GPIOs using DT property gpio-initval

Hi,

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

The previous patch was '[PATCH v2] gpio: Allow hogged gpios to be requested'
which would have allowed to request hogged GPIOs. Linus suggested a separate DT
property as hogged gpios should not be requested.

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

  gpio: Use __gpiod_request directly
  gpiolib: gpiod_hog remove separate name argument
