From 5370a431ef915b52697d25a5a32cbaf9a4cbef95 Mon Sep 17 00:00:00 2001 From: Sakari Ailus Date: Wed, 13 Dec 2023 11:40:55 +0200 Subject: mei: vsc: Rework firmware image names Rework firmware image names with the users in mind---there's no need for variation between firmware names, apart from connected sensors. All supported SoCs use the same firmware, too. Use a single set of firmware binaries and assume they'll be found under intel/vsc directory.
