From 5f69f49a942cd31e5f8b511e166fb55e3a0df267 Mon Sep 17 00:00:00 2001
From: Maxime Ripard <maxime@cerno.tech>
Date: Tue, 26 May 2020 14:30:31 +0200
Subject: [PATCH] clk: bcm: rpi: Give firmware clocks a name
We've registered the firmware clocks using their ID as name, but it's much
more convenient to register them using their proper name. Since the
firmware doesn't provide it, we have to duplicate it.
