From: Sascha Hauer <s.hauer@pengutronix.de> To: Barebox List <barebox@lists.infradead.org> Cc: Ahmad Fatoum <a.fatoum@pengutronix.de> Subject: [PATCH 05/24] clk: introduce clk_register() Date: Wed, 2 Jun 2021 11:54:48 +0200 [thread overview] Message-ID: <20210602095507.24609-6-s.hauer@pengutronix.de> (raw) In-Reply-To: <20210602095507.24609-1-s.hauer@pengutronix.de> This introduces a clk_register() with the same semantics as in Linux. This also adds a struct clk_init_data. With this it becomes easier to port over new clock drivers from Linux.
