Raspberry Pi RP1 PCI Device Support On Path For Linux 6.17 Upstreaming
Going back to last year there have been patches worked on by SUSE for upstreaming Raspberry Pi's RP1 PCI device support
Andrea della Porta of SUSE has been working on getting more elements of the Raspberry Pi 5 support upstreamed into the mainline Linux kernel. As described by Andrea on the patch series:"RP1 is an MFD chipset that acts as a south-bridge PCIe endpoint sporting a pletora of subdevices (i.e. Ethernet, USB host controller, I2C, PWM, etc.) This patchset is an attempt to provide a minimum infrastructure to allow the RP1 chipset to be discovered and perpherals it contains to be added from a devictree overlay loaded during RP1 PCI endpoint enumeration.
