Hi Linus,

thanks for the tips, I will study this to break dependency from OF.

Best Regards,

For generic pinconf: print the dev_error with the pinctrl vendor
driver name, error code, the sub-node property name used and the
pin that was tried to set.

Improves the undestading of the error if use a generic sub-node
property that generic-pinconf can do parse but the vendor pinctrl
driver does not support.

This doesn't seem right.

If this is restricted for OF only the root cause to why it is
like that needs to be found and the code refactored to fit anyone,
there is also ACPI support in the works I think, surely they should
be able to get verbose messages.

dev_err(pctldev->dev,
- "pin_config_set op failed for pin %d\n",
+ "%s error %d setting %s for pin %d\n",
+ pctldev->desc->name, ret,
+ pinconf_generic_get_param_property_name(
+ pctldev, setting->data.configs.num_configs,
+ setting->data.configs.configs),
setting->data.configs.group_or_pin);

This doesn't seem right. First argument is a %d, yet this
is pctldev->desc->name?

Something is fishy with the argument list.

Yours,
