2019-10-04pinctrl: devicetree.c: remove orphan pinctrl_dt_has_hogs()Rasmus Villemoes1-7/+0
The helper pinctrl_dt_has_hogs() was introduced in 99e4f67508e1 (pinctrl: core: Use delayed work for hogs), but the sole use then got removed shortly after in 950b0d91dc10 (pinctrl: core: Fix regression caused by delayed work for hogs).

2017-01-03pinctrl: core: Use delayed work for hogsTony Lindgren1-2/+10
Having the pin control framework call pin controller functions before it's probe has finished is not nice as the pin controller device driver does not yet have struct pinctrl_dev handle. Let's fix this issue by adding deferred work for late init. This is needed to be able to add pinctrl generic helper functions that expect to know struct pinctrl_dev handle. Note that we now need to call create_pinctrl() directly as we don't want to add the pin controller to the list of controllers until the hogs are claimed. We also need to pass the pinctrl_dev to the device tree parser functions as they otherwise won't find the right controller at this point.

2012-04-18pinctrl: core device tree mapping table parsing supportStephen Warren1-0/+35
During pinctrl_get(), if the client device has a device tree node, look for the common pinctrl properties there. If found, parse the referenced device tree nodes, with the help of the pinctrl drivers, and generate mapping table entries from them. During pinctrl_put(), free any results of device tree parsing.
