arm64: dts: marvell: cn9132-clearfog: fix multi-lane pci x2 and x4 ports
The mvebu-comphy driver does not currently know how to pass correct lane-count to ATF while configuring the serdes lanes. This causes the system to hard reset during reconfiguration, if a pci card is present and has established a link during bootloader. Remove the comphy handles from the respective pci nodes to avoid runtime reconfiguration, relying solely on bootloader configuration - while avoiding the hard reset. When bootloader has configured the lanes correctly, the pci ports are functional under Linux. This issue may be addressed in the comphy driver at a future point. Fixes: e9ff907f4076 ("arm64: dts: add description for solidrun cn9132 cex7 module and clearfog board") Cc: stable@vger.kernel.org Signed-off-by: Josua Mayer <josua@solid-run.com> Signed-off-by: Gregory CLEMENT <gregory.clement@bootlin.com>
