From a9c61ac04fdef8de7842456ff597db375f8b48d8 Mon Sep 17 00:00:00 2001 From: Gokul Praveen Date: Tue, 26 Nov 2024 16:21:30 +0530 Subject: serial: ns16550: Increase scope of ops functions Increase scope of ops functions and do some clean up for usage in device -specific UART drivers. Remove the static functionality of ops functions and migrate certain macros to header file for usage in device-specific drivers.
