Subject: [PATCH v9 2/7] clk: rockchip: handle missing clocks with -EPROBE_DEFER
Date: Mon, 25 Mar 2024 20:33:33 +0100	[thread overview]
Message-ID: <20240325193609.237182-3-sebastian.reichel@collabora.com> (raw)
In-Reply-To: <20240325193609.237182-1-sebastian.reichel@collabora.com>

In the future some clocks will be registered using CLK_OF_DECLARE
and some are registered later from the driver probe routine. Any
clock handled by the probe routine should return -EPROBE_DEFER
until that routine has been called.
