Subject: [PATCH 2/3] clk: add prepare/unprepare helpers
Date: Fri, 9 Dec 2022 08:10:01 +0100 [thread overview]
Message-ID: <20221209071002.3765134-2-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20221209071002.3765134-1-a.fatoum@pengutronix.de>
barebox doesn't use interrupts, so it need not differentiate between a
possibly sleeping prepare/unprepare and an atomic enable/disable.
Provide a wrapper that just expands to the already existing functions to
simplify porting of Linux kernel drivers.
