drm/tinydrm: add driver for ST7735R panels

2018-01-03T12:54:24+00:00

This adds a new driver for Sitronix ST7735R display panels. This has been tested using an Adafruit 1.8" TFT.

drm/tinydrm: Update ILI9225 compatible string

2018-01-03T12:52:53+00:00

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.

drm/tinydrm: Use drm_fb_cma_fbdev_init_with_funcs/fini()

2017-12-10T14:37:07+00:00

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.

drm/tinydrm: add driver for ILI9225 panels

2017-12-01T13:08:37+00:00

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 .

This exports the mipi_dbi_buf_copy() and mipi_dbi_spi_cmd_max_speed() functions so that they can be shared with other drivers.
