From 20af71dc6470e65c8d7f14810d43f340ffd0c60d Mon Sep 17 00:00:00 2001 From: Furquan Shaikh Date: Sat, 27 Jun 2020 13:04:47 -0700 Subject: soc/amd/common/gpio: Add macros for setting fields of soc_amd_gpio MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This change adds helper macro PAD_CFG_STRUCT for setting the fields of `soc_amd_gpio`. Additionally, macros are added for different operations i.e. pull, output, trigger, int_enable, event_trigger, wake_enable, debounce, etc. All GPIO configuration macros are updated to use PAD_CFG_STRUCT instead of setting the fields directly.
