From 6a97cd39b6ba9372240e24e44cc3c6a0d89532e9 Mon Sep 17 00:00:00 2001 From: Vadim Yanitskiy Date: Fri, 8 Apr 2022 01:22:37 +0300 Subject: Move power control related definitions to power_control.h Now that we have separate header/code files for the power control, let's move the related definitions there. This change makes the code consistent with osmo-bts, where it's already done this way.
