The device is sold under the name ZX_SWTGW215AS without necessarily
a Hasivo branding, however the firmware and the PCB are marked with
Hasivo. The PCB is marked Hasivo RTL_SGT-1SX V1.5
SoC: RTL8372
Ethernet: 5 x 2.5GBit (RTL8221B + 4*SoC)
SFP+: 1x 10GBit (SoC)
The device has a slider switch and a reset button.
Reset: GPIO 54 (active-low)
Slider: GPIO 51 (right is high)
RTL has up to 3 SCL pins and up to 4 SDA pins. Lets allow configuring
I2C with individual BUS numbers instead of 0/1 I2C.
This enables support for devices where SCL line is not shared between
SFP modules. MUX registry is now initialized depending on needed
pin function.
More over, some SFP pins require special MUX settings, lets initialize
those depending on SFP configuration. This adds TX Disable pin,
which right now is set to low at startup.
Caveats:
- We may still override MUX registry later
- Not sure how to handle invalid bus definitions
- Without SFP is it fine to *not* initialize anything?
- Do to RAM limitation we do inititalize output GPIO to low
Detect the SOC type and variant. RTL8372 vs RTL8373 and also is it as
non-N/N variant of the SOC.
Even if the machine profile is wrong the hardware will be initilised on
the detected type.
