Subject: [PATCHv3 22/26] arm: mach-k3: j721e_init: Force early probe of clk-k3 driver
Date: Wed, 5 May 2021 20:55:36 +0300 [thread overview]
Message-ID: <20210505175540.15006-23-kristo@kernel.org> (raw)
In-Reply-To: <20210505175540.15006-1-kristo@kernel.org>
From: Dave Gerlach <d-gerlach@ti.com>
Force the clk-k3 driver to probe early during R5 SPL boot to ensure the
default system clock configuration is completed. Many other drivers
assume a default state of the clock tree and it is currently possible
for them to probe before clk-k3 depending on the exact system
configuration.
