[ Upstream commit f4fd559de3 ]
This reverts commit 830aa6f29f.
This is part of a revert of the following commits:
11ed8b8624 ("PCI: brcmstb: Do not turn off WOL regulators on suspend")
93e41f3fca ("PCI: brcmstb: Add control of subdevice voltage regulators")
67211aadcb ("PCI: brcmstb: Add mechanism to turn on subdev regulators")
830aa6f29f ("PCI: brcmstb: Split brcm_pcie_setup() into two funcs")
Cyril reported that 830aa6f29f ("PCI: brcmstb: Split brcm_pcie_setup()
into two funcs"), which appeared in v5.17-rc1, broke booting on the
Raspberry Pi Compute Module 4. Apparently 830aa6f29f panics with an
Asynchronous SError Interrupt, and after further commits here is a black
screen on HDMI and no output on the serial console.
This does not seem to affect the Raspberry Pi 4 B.
