Sure, I can take that, but it would be nice to hear anything from Jisheng Zhang
about this.

I can see that the only two 64-bit Synaptics SoCs are as370 and bg4ct,
but both of them have apparently been replaced with newer versions that
never made it into the kernel: as371, as390, bg5ct, according to press
releases.

Jisheng, can you clarify whether you plan to complete the as370 support
or add the later SoCs?
