2018-01-03drm/tinydrm: Update ILI9225 compatible stringDavid Lechner
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.

2017-12-10drm/tinydrm: Use drm_fb_cma_fbdev_init_with_funcs/fini()Noralf Trønnes
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.

2017-12-01drm/tinydrm: add driver for ILI9225 panelsDavid Lechner
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.
