Thanks for submitting this so we can review and discuss.

These should be dropped as they are vendor drivers that will never be
upstream as fbdev is deprecated [1]. StarFive is working on DRM driver
but that is a couple months away from being ready.

Before this gets merged upstream, we need to switch over to using JH7100
instead of VIC.

For those not familiar, VIC was the StarFive internal project name but
the product is named JH7100 [2].

This config is being used in as a vendor hack in i2c_dw_configure_gpio()
drivers/i2c/busses/i2c-designware-master.c [3].

It's possible we may be able to eliminate this once I have completed
gpio and pinctrl drivers. Either way, this option will never be used in
an upstream kernel.

These should be dropped as they are vendor drivers that do not use V4L2
and are not upstreamable [4]. StarFive is working on proper V4L2 drivers
but that is a couple months away from being ready.

I am working on upstreamable version of the GPIO driver and will submit
RFC soon. This will be called CONFIG_GPIO_STARFIVE_JH7100.
