From 2c8cb236ed44d071ef2ed1fbb948eea404551788 Mon Sep 17 00:00:00 2001 From: Prashant Malani Date: Thu, 12 Jan 2023 22:16:07 +0000 Subject: [PATCH] usb: typec: Add wrapper for bus switch set code Add a wrapper that calls the set() function for various switches associated with a port altmode. Right now, it just wraps the existing typec_mux_set() command, but it can be expanded to include other switches in future patches. No functional changes introduced by this patch.
