Added a custom device driver to GSRD 14.1
The IP is contained in sopc0: hps_0_bridges: bridge@0xc0000000
of_match_device - is successful -
Looking in my: /proc/device-tree/sopc@0/bridge@0xc0000000/serial@0x100040000
When I do # ] hexdump -C 'compatible'
I can see my entries that match with the of_match [] of the device driver
When I do# ] hexdum -C 'reg'
I see the values in my dev entry
BUT, the platform_get_resource fails.

I had a line missing in my .dts file so I generated another .dtb file and now the driver loads. STILL HAVE A PROBELM - when I use the driver I should see activity on a couple of the Cyclone V Dev kit board HSMC - but the lines aren't toggling. So - WHAT AM I MISSING? I have: 1. generated the .dtb, .rbf and added them to the microSD card. I have cross compiled my device driver and put it on the microSD card and simply done an "insmod myDriver.ko" - I saw that maybe I needed a new preloader image so I created a new on of those.
