Yeah,it should be populated.
I gotta check the syntax in DTS.
Try images from the same gdrive url and report if something has changed.
I found syntax error and missing aliases for power LED.
Rebuilt and images are here:https://drive.google.com/drive/folders/1VyDlOlNVAbQTE8CF7VQHTvNyEuc8SfDl?usp=sharing
Same result:
We've been sent home from work due to snow, so I've brought the WAC510 home with me. I'll fork your github to my home PC and fiddle with the DTS..
Tim
Then shift register is not registered correctly.
Also,did you use your board-2.bin or one in my branch?
Can you check if it registered?
Can I just check /proc/device-tree/soc to see if it's registered? If so, here's the contents of that:

I just used your initramfs from your gdrive for the latest bootlog, nothing of mine.. I'm still cloning/compiling your branch on my laptop 
Tim
OK,then I know whats the issue with board-2.bin
Will fix that now.
You can see that led_spi is registered.
But you can see /sys/class/devices
There should be HC595 under led_spi
I've only got /sys/class/leds, and it's empty..
Tim
Yeah,I told you wrong.
Under /sys there should be devices folder.
HC595 has to be registered somewhere there.
Can you also run lsmod to see if kernel module is loaded at all
Here's the contents of /sys/devices and the loaded modules:

Yeah,it looks like it is registered.
I dont understand why then arent leds being registered.
Can I help? I'm a little out of my depth, but I'll give it a go!
Tim
I dont know,I have no idea why they are not registering.
It would be good for someone else to look at DTS,most likely its simple syntax error but its hard to spot when you checked that DTS for multiple times

Is the DTS in your WAC510 github branch? I can have a look, for what it's worth..
Tim
Yes,it is here:
I've managed to unpack a Netgear 'firmware upgrade', and have access to the squashfs filesystem. Would that be any help?
Tim
That really depends on whats inside.
Perhaps a copy of the DTS they use? Mind you, I extracted the DTS from the firmware's kernel already and you've already seen that.. OK - bad idea
Tim
I doubt it.
I already saw DTS they use,they are using reference DTS for SPI+NAND.
DK01-C2 exactly.
I have a couple of probably very silly questions:
As far as I understand it, the SoC uses it's GPIO pins as an SPI bus to talk to the shift register, right? So, the kernel is registering the shift register on those GPIO pins, but it's not 'seeing' the shift register? Is that right?
Does that mean perhaps the GPIO's for the SPI bus aren't right? I'm pretty sure gpio5 is one of them, but I'm not sure on the other..
What about that 'compatible' string? The chip is a 74hc164, which has a kernel module gpio_74x164. Shouldn't that be referenced somewhere? Why does it say 'fairchild,74hc595'?
