From cf5aa374252dee2469c011fa517ff43148da6e42 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Fri, 24 Feb 2023 14:12:50 +0100 Subject: [PATCH 0563/1085] clk: bcm: rpi: Add disp clock BCM2712 has an extra clock exposed by the firmware called DISP, and used by (at least) the HVS. Let's add it to the list of clocks to register in Linux.
