Aftert running successfully with the 4.19 kernel (Ayufan's) , SPI booting with  a USB3 ssd,  I found that after installing 4.20 I could no longer boot from the USB drive.  Booting from SD worked,  but none of my drives, a Samsung T1,  a sandisk Extreme stick,  or  WD passport would even be powered/recognized from any of the USB ports .  If I boot with the 4.19 dtb on the 4.20 kernel, eveything boots/is recognized again.  If I change the following lines in the rk3328-rock64.dts (from 4.20) to their 4.19 values and recompile ,  disk recognition/booting works again.


vcc_host1_5v: vcc_otg_5v: vcc-host1-5v-regulator {#############################  from 4.20,  changed A2 back to D3  to make things work
compatible = "regulator-fixed";
enable-active-high;
gpio = <&gpio0 RK_PA2 GPIO_ACTIVE_HIGH>;




usb2 {
usb20_host_drv: usb20-host-drv {
rockchip,pins = <0 RK_PA2 RK_FUNC_GPIO &pcfg_pull_none>;#################  from 4.20,  changed A2 back to D3  to make things work

My board is version 2.0

This problem did not affect other usb devices, btw,  just storage...  I tried to check the specs but didn't see find anything for vcc_host1_5v ,  vcc_otg_5v or usb20_host_drv.

I did find usb_otg_drv at A2.....

Could anyone clarify what is going on?  I'm pretty clueless about hardware.'

I did see a complaint about this on the Arch forums,  but none of the armbian people seemed to have run into it.

Thanks.
