Subject: [PATCH 08/13] clk: implement clk_hw_reparent
Date: Mon, 27 Nov 2023 07:49:42 +0100	[thread overview]
Message-ID: <20231127064947.2207726-9-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20231127064947.2207726-1-a.fatoum@pengutronix.de>

clk_hw_reparent does a bit of work in Linux to update the cached clock
tree, but we have no cached clock tree in barebox, so just implement it
as empty stub.
