Masahiro, have a look at the call to set_state_simple from pinctrl_select_state_simple (in drivers/pinctrl/pinctrl-uclass.c). It is at this point that the pinctrl node becomes the 'dev' parameter, and the former 'dev' then becomes the second 'periph' parameter. --- /* * For simplicity, assume the first device of PINCTRL uclass * is the correct one. This is most likely OK as there is * usually only one pinctrl device on the system. */ ret = uclass_get_device(UCLASS_PINCTRL, 0, &pctldev); if (ret) return ret; ops = pinctrl_get_ops(pctldev); if (!ops->set_state_simple) { dev_dbg(dev, "set_state_simple op missing\n"); return -ENOSYS; } return ops->set_state_simple(pctldev, dev); --- Reviewed-by: James Balean <ja...@balean.com.au> -- Kind regards, James Balean _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
