From 5a25e2437af0db535b17da352fb16680a8dfdeda Mon Sep 17 00:00:00 2001 From: Tudor Ambarus Date: Wed, 3 Feb 2021 17:43:32 +0200 Subject: [PATCH 112/247] clk: at91: Fix the declaration of the clocks These are all "early clocks" that require initialization just at of_clk_init() time. Use CLK_OF_DECLARE() to declare them. This also fixes a problem that was spotted when fw_devlink was set to 'on' by default: the boards failed to boot. The reason is that CLK_OF_DECLARE_DRIVER() clears the OF_POPULATED and causes the consumers of the clock to be postponed by fw_devlink until the second initialization routine of the clock has been completed. One of the consumers of the clock is the timer, which is used as a clocksource, and needs the clock initialized early. Postponing the timers caused the fail at boot.
