Radxa Cubie A5E

found out that the pcie ip is actually designware. So it may work with the existing driver + some init stuff like clocks, resets, regulators, power domains and whatever

the official linux/bsp image has the same throughput
i think in has an 100mhz internal clock, it uses just the main 24Mhz oscilator from the board
the bsp version also uses the nsi controller which seems to be some pm bus management crap but it doubt it changes much
so what the actual fsck is a nsi controller ? (it's not in the soc manual)

files modified vs 14.3 here

cubie-arm - Google Drive

drive.google.com drive.google.com
it contains all the allwinner and rk356x stuff i have changed

vs official tree
cubie has both ethernets, pcie, cpu freq, usb2, thermal, i2c, gpio, serial flash controller, sd card
rk3566 has drm video + panfrost + analog sound + ahci, serial flash controller, hardware rng
h616 clocks/gpio/sd/mmc/analog sound/pwm ng/dma/pmics not tested after importing from 13.x
