Linux Patches Work To Upstream Raspberry Pi's RP1 PCI Device Support
Andrea della Porta of SUSE has been working on upstreaming the Linux kernel support to boot the Raspberry Pi 5 on a mainline kernel
Andrea della Porta explained with :"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. We're quickly approaching one year since the release of the Raspberry Pi 5 in October and at this rate it's looking like by that point the mainline kernel will still not yet have full upstream support for this popular ARM64 SBC.About The AuthorMichael Larabel is the principal author of Phoronix.com and founded the site in 2004 with a focus on enriching the Linux hardware experience.
