Sources for linux-dtb-current-sunxi64?

Banana Pi BPI-M64 Linux

I tried to load the source code for linux-dtb-current-sunxi64, but apt-get is complaining:

gollumm64% sudo apt-get source linux-dtb-current-sunxi64
[sudo] password for heller: 
Reading package lists... Done
Picking 'linux-5.4.43-sunxi64' as source package instead of 'linux-dtb-current-sunxi64'

How do I get the source code for this package? I’d like to modify /boot/dtb-5.4.43-sunxi64/allwinner/sun50i-a64-bananapi-m64.dtb – I think I need to change something in it to enable the eMMC.

… if its just enabling.

Yes, I just need to enable the eMMC. I install the kernel source tree and tied to modify the DTS and did build an alternitive version of the dtb, but that did not help.

Well, nevermind. In the process of following posts to try to get the camera working, I managed to upgrade the kernel (to 5.7.15-sunxi64), and suddenly /dev/mmcblk2 showed up (but not the camera…).
