Subject: [PATCH 01/32] clk: define stub implementation for clk_get_parent
Date: Mon,  5 Sep 2022 11:55:26 +0200	[thread overview]
Message-ID: <20220905095557.596891-2-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20220905095557.596891-1-a.fatoum@pengutronix.de>

To make it easier to build drivers utilizing clk_get_parent on sandbox
for static analysis, provide a stub implementation of the function.
