This is a patch series for USB HOST OHCI driver for Sunplus SP7021 SoC.

Sunplus SP7021 is an ARM Cortex A7 (4 cores) based SoC. It integrates
many peripherals (ex: UART, I2C, SPI, SDIO, eMMC, USB, SD Card and
etc.) into a single chip. It is designed for industrial control.

Looks to me like the generic-ohci binding and driver should work for 
this?

The generic-ohci binding and driver did work for Sunplus SP7021.
And do I need to submit the patch for the ohci driver and binding doc
for Sunplus
SP7021 SoC ?

Just need to add the compatible string to the generic-ohci binding. For 
the driver, I don't know, did you have to change anything?
