currently gpio hog function is not tested with "ut dm gpio"
so add some basic tests for gpio hog functionality.
For this enable GPIO_HOG in sandbox_defconfig, add
in DTS some gpio hog entries, and add testcase in
"ut dm gpio" command.

This no longer applies cleanly/obviously, please rebase, thanks!
Done, unfortunately, aristainetos2 does not boot anymore... got:

Seems early SPI NOR detection fails ...
Have to start bisect, try to find some time...
Ok, commit:
commit 788ea834124bd6169ea10b2d37d5de48a2dd28a0 (bisect-788ea83412)

gpio: add function _dm_gpio_set_dir_flags
Introduce the function _dm_gpio_set_dir_flags to set dir flags
without check if the GPIO is reserved.
Separate the reserved check for "set_dir" and "set_dir_flags".
This patch is a preliminary step to add new ops.

breaks the aristainetos2 board ... reverting this patch (and therefore

And board boots again fine ...
I do not see, why commit 788ea834124bd6169ea10b2d37d5de48a2dd28a0
makes SPI not working anymore ...
Any ideas?
Just looking with sandbox into it ... added debug patch:

It looks like the plat->gpiod_flags are not written anymore into gpiod
through the gpio_dev_request_index() function ...
