A recent Pi 5 Model B Rev 1.1 with 8GB reports a HW Revision 0xd04171 and results in code -3 (HW revision not supported)

[afalk42]

I encountered a Pi 5 that reports hwver = 0xd04171 and, therefore, resulted in a code -3 error in ws2811_init from the Python wrapper. This is the output from cat /proc/cpuinfo on that Pi 5:

Revision        : d04171
Serial          : ***************
Model           : Raspberry Pi 5 Model B Rev 1.1

To fix this issue, I would suggest to add the following lines to rpihw.c:

    {
        .hwver  = 0xd04171,
        .type = RPI_HWVER_TYPE_PI5,
        .periph_base = 0,           // uses kernel driver
        .videocore_base = 0,        // uses kernel driver
        .desc = "Pi 5 Model B Rev 1.1 - 8GB",
    },
