It has been observed on BCM2835 that IMA -is initialised before TPM, and that initialising the BCM2835 clock -driver before the firmware driver has the effect of reversing this -order. - -Change the firmware driver to initialise at core_initcall, delaying the -BCM2835 clock driver to postcore_initcall. - -See: https://github.com/raspberrypi/linux/issues/3291 - https://github.com/raspberrypi/linux/pull/3297 - -Signed-off-by: Luke Hinds <lhinds@redhat.com> -Co-authored-by: Phil Elwell <phil@raspberrypi.org> ---- - drivers/clk/bcm/clk-bcm2835.c | 2 +- - drivers/firmware/raspberrypi.c | 2 +- - 2 files changed, 2 insertions(+), 2 deletions(-) - ---- a/drivers/clk/bcm/clk-bcm2835.c -+++ b/drivers/clk/bcm/clk-bcm2835.c -@@ -2388,7 +2388,7 @@ static int __init __bcm2835_clk_driver_i - { - return platform_driver_register(&bcm2835_clk_driver); - } --core_initcall(__bcm2835_clk_driver_init); -+postcore_initcall(__bcm2835_clk_driver_init); - - MODULE_AUTHOR("Eric Anholt <eric@anholt.net>"); - MODULE_DESCRIPTION("BCM2835 clock driver"); ---- a/drivers/firmware/raspberrypi.c -+++ b/drivers/firmware/raspberrypi.c -@@ -404,7 +404,7 @@ out2: - out1: - return ret; - } --subsys_initcall(rpi_firmware_init); -+core_initcall(rpi_firmware_init); - - static void __init rpi_firmware_exit(void) - { |
