Hello,
This patch-set adds support for the family of SSD133x Solomon controllers,
such as the SSD1331. These are used for RGB Dot Matrix OLED/PLED panels.
The patches were tested on a Waveshare SSD1331 display using glmark2-drm,
fbcon, fbtests and the retroarch emulator.

The drm_dev field in the rk3066_hdmi struct stores a pointer to the DRM
device but is never used anywhere in the driver. Let's remove it.

Implement netdev devmem allocator. The allocator takes a given struct
netdev_dmabuf_binding as input and allocates net_iov from that
binding.
The allocation simply delegates to the binding's genpool for the
allocation logic and wraps the returned memory region in a net_iov
struct.

The Solomon SSD133x controllers (such as the SSD1331) are used by RGB dot

The SSD133x controllers support 256 (8-bit) and 65k (16-bit) color depths
but only the former is implemented for now. This is because the 256 color
