From 1231dbeb8bfeda68c53854cc68016acd74665079 Mon Sep 17 00:00:00 2001
From: Maxime Ripard <maxime@cerno.tech>
Date: Fri, 7 Feb 2020 16:08:17 +0100
Subject: [PATCH] clk: bcm: rpi: Pass the clocks data to the firmware
function
The raspberry_clock_property only takes the clock ID as an argument, but
now that we have a clock data structure it makes more sense to just pass
that structure instead.
