pinctrl.txt: Remove outdated information
Returning -EAGAIN is no longer supported by pin_config_group_set()
since ad42fc6c84
("pinctrl: rip out the direct pinconf API")
Remove the relevant section from the documentation.

Since some controllers have special logic for handling entire groups of pins
|
|
||||||
they can exploit the special whole-group pin control function. The
|
|
||||||
pin_config_group_set() callback is allowed to return the error code -EAGAIN,
|
|
||||||
for groups it does not want to handle, or if it just wants to do some
|
|
||||||
group-level handling and then fall through to iterate over all pins, in which
|
|
||||||
case each individual pin will be treated by separate pin_config_set() calls as
|
|
||||||
well.
