From cf0a95659e659d36838e56cc439d3986dcb46870 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Thu, 22 Jul 2021 22:34:50 +0300 Subject: clk: x86: Rename clk-lpt to more specific clk-lpss-atom The LPT stands for Lynxpoint PCH. However the driver is used on a few Intel Atom SoCs. Rename it to reflect this in a way how another clock driver, i.e. clk-pmc-atom, is called.
