The Broadcom pcie setup has a devicetree dependency like: /pcie/paxdma -> /pcie/pcie -> /soc/pl330 Add a separate init symbol for iproc_pax_v2 so that these gets initialized in order, fixes this error: $ west build -p -b bcm958402m2_m7 tests/kernel/common \ -DCONFIG_CHECK_INIT_PRIORITIES=y ... ERROR: /pcie/paxdma@4e100800 POST_KERNEL 40 < \ /pcie/pcie@4e100000 POST_KERNEL 50 Signed-off-by: Fabio Baltieri <fabiobaltieri@google.com>
