From: Nicolas Saenz Julienne <nsaenz@kernel.org> stable inclusion from stable-5.10.75 commit 6e6e3018d3ced1cc1f7115f29221fc5ba793a2a2 bugzilla: 182987 https://gitee.com/openeuler/kernel/issues/I4I3MP Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- commit 3f32472854614d6f53b09b4812372dba9fc5c7de upstream. The unit address is supposed to represent '<device>,<function>'. Which are both 0 for RPi4b's XHCI controller. On top of that although OpenFirmware states bus number goes in the high part of the last reg parameter, FDT doesn't seem to care for it[1], so remove it.
