Subject: [PATCH 05/17] of: base: move clock init from of_probe() to barebox_register_of()
Date: Thu,  6 May 2021 11:28:49 +0200
Message-ID: <20210506092901.25461-6-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20210506092901.25461-1-s.hauer@pengutronix.de>

From: Marco Felsch <m.felsch@pengutronix.de>

This is required for the new deep-probe mechanism. Barebox deep-probe
calls of_probe() very late and so clock drivers using the old
CLK_OF_DECLARE_DRIVER() mechanism are added very late. This would break
the deep-probe approach.

Move of_clk_init() and call it right before of_probe() should have no
impact because of_clk_init() depends only on an unflatten dtb.
