I decided to start with inital support (without GENET, thermal, HWRNG, USB 3.0, 40 bit DMA, V3D) and handle the advanced topics separate. But yes there is a ticket for the initial support: https://github.com/lategoodbye/rpi-zero/issues/43 > I noticed you posted a v2 series this morning.

The good news: sdhci (without clock) and pinctrl changes has been merged for Linux 5.4.
