From c630cf8f3a6cc3048f8c78b130a9ce9749b81b30 Mon Sep 17 00:00:00 2001 From: Dmitry Baryshkov Date: Fri, 16 Feb 2024 13:14:58 +0200 Subject: clk: qcom: drop the SC7180 Modem subsystem clock driver This driver has never been used in the DT files merged to the kernel. According to Sibi, it only worked on the pre-production devices. For the production devices this functionality has been moved to the firmware. Drop the driver to remove possible confusion.
