David Lechner f3125a545d drm/tinydrm: Update ILI9225 compatible string
This updates the compatible string for a no-name LCD panel to
"vot,v220hf01a-t", "ilitek,ili9225".

The original bindings were the generic "ilitek,ili9225-2.2in-176x220"
because I could not find a datasheet. However, after some more research,
I finally found one, so the actual vendor and model name are now known.

This previous bindings have not made it to the mainline kernel yet, so
this is not breaking backwards compatibility.

Noralf Trønnes d3820952ea drm/tinydrm: Use drm_fb_cma_fbdev_init_with_funcs/fini()
Use drm_fb_cma_fbdev_init_with_funcs() and drm_fb_cma_fbdev_fini() which
relies on the fact that drm_device holds a pointer to the drm_fb_helper
structure. This means that the driver doesn't have to keep track of that.
Also use the drm_fb_helper functions directly.
Remove todo entry.

David Lechner b57e8b7661 drm/tinydrm: add driver for ILI9225 panels
This adds a new driver for display panels based on the Ilitek ILI9225
controller.

This was developed for a no-name panel with a red PCB that is commonly
marketed for Arduino. See <https://github.com/Nkawu/TFT_22_ILI9225>.
