From 5f69b867f0c9ec9c0afab4df70a3d0d06809957a Mon Sep 17 00:00:00 2001 From: Matt DeVillier Date: Fri, 23 Sep 2022 14:51:12 -0500 Subject: mb/google/skyrim: Allow variants to override romstage GPIO table Switch from gpio_configure_pads() to gpio_configure_pads_with_override() so variants can override romstage GPIO defaults. Rename baseboard function and add an weak empty override function to be used by variants. Will be used for touchscreen power sequencing in a follow-on commit.
