From eaa4c8f953ba1d2eafb1c961aa9321beb71f21c9 Mon Sep 17 00:00:00 2001 From: Ryan Wanner Date: Fri, 7 Oct 2022 08:16:47 -0700 Subject: [PATCH] pinctrl: at91-pio4: Add persist state case in config Adding persist state case to atmel_conf_pin_config_group_set() function. After adding configuration support for userspace gpiod api, there was an extra flag PIN_CONFIG_PERSIST_STATE that was not passed in before. Based on other drivers like TI drivers, added a switch case and return ENOTSUPP in that case.
