From 61305e00c704aa3c4ccf73598074ada4e55185fd Mon Sep 17 00:00:00 2001 From: Dave Gerlach Date: Fri, 11 Jun 2021 11:45:23 +0300 Subject: [PATCH] arm: mach-k3: j721e_init: Force early probe of clk-k3 driver 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.
