LD9040 CS is active low, so this board needs probably the same fix a
Universal C210 board: https://patchwork.kernel.org/patch/11420231/ Are
you sure it really works now with v5.6-rcX kernels? Or you just got the
panel working only because the bootloader enabled it?

Sorry but the fix looks bogus to me. The spi-gpio driver calls gpiod_set_value(0) when the CS is going *active*, and gpiod_set_value(1) when the CS is going *inactive*. If you use the GPIO_ACTIVE_LOW flag, the levels are inverted, and the CS is high when active, which is the opposite of what you want.

The the host mode really works with DWC2? Afair the host mode worked
only when it was rerouted by PHY to the EHCI (at least on UniversalC210
board, which is very similar to GS2).

I have to say that I didn't try OTG / host, but it does work fine in gadget mode.
I can change it to dr_mode = "peripheral" for now, if you prefer.

This is the old, obsolete exynos-ehci binding. Please remove 'port'
nodes and use standard USB phy bindings like it has been done in the
following patch: https://patchwork.kernel.org/patch/11060465/

Will do.

BTW, do you really need all 3 phys/ports?

No idea!
