From 77401d7fdfcdcb233864f7a6edc1e15b4f5d56d9 Mon Sep 17 00:00:00 2001 From: Dan O'Donovan Date: Fri, 10 Jun 2016 13:23:36 +0100 Subject: [PATCH] pinctrl: cherryview: add handlers for pin_config_group_get/set Pin config get/set handlers for pin groups were previously not implemented by this driver. The pin_config_group_set is particularly useful for applying a common config setting to all pins in a specified group with a single call, without the caller needing to reference each individual pin by name.
