SUSE Working To Upstream RP1 Southbridge Linux Driver For The Raspberry Pi 5
The Raspberry Pi 5 features the 'RP1' as the in-house silicon design for the southbridge to this single board computer
Andrea last month posted patches so the upstream kernel can boot on the Raspberry Pi 5 while the latest change is on supporting the RP1 southbridge. Raspberry Pi's RP1 southbridge provides for four lanes of PCI Express 2.0, Gigabit Ethernet MAC, two USB 3 host controllers, dual SDIO ports / eMMC, two MIPI transceivers, a video DAC, low-speed peripherals, and PWM audio out. But long story short it looks like it will still be some months before potentially having all of the Raspberry Pi 5 bits working well in a mainline Linux kernel version.
