Subject: [PATCH 0/3] Fix handling of multi-level OF nodes
Date: Thu, 5 Aug 2021 10:28:57 +0200 [thread overview]
Message-ID: <cover.1628151760.git.mchehab+huawei@kernel.org> (raw)
Hi Rob,
This series address the issues related to not add all of_node data at sysfs.
Patch 1 is the real fix.
Patch 2 just changes the order of init, in order to allow printing what's
happening when registering a device;
Patch 3 is just debug.
With patch 1 applied, the sysfs nodes seem to match the PCI configuration:
$ find /sys/devices/platform/soc/f4000000.pcie/ -name of_node
/sys/devices/platform/soc/f4000000.pcie/of_node
