I'm having issues with the RK3399 even recognising that there is a PCIE bus let alone getting it to work
It appears from the following that the voltage regulator is not configured to feed the pcie:
- [ 0.261544] of_get_named_gpiod_flags: parsed 'gpio' property of node '/vcc3v3-pcie-regulator[0]' - status (0)

Copy the code
but some of the other bits are configured to provide power. I've been looking at the device tree files, but I'm a bit stuck as to what is missing - I don't really know what the gpio parameters are, and the only thing I can think of doing is setting it to be always on by setting it's voltage parameter to 3300000 in the dts like it is for vcc3v3_sys
any ideas?
