[PATCH v2 0/6] fbtft: make it work with DMA enabled SPI

Show all headers | View raw

This series enables 64x48 OLED display and fixes the driver to work with DMA
enabled SPI properly.

Has been tested on Intel Edison board with Adafruit 2'8" and SSD1306 64x48
(Sparkfun for Intel Edison) OLED displays at their maximum speed (25MHz and
10MHz).

Andy Shevchenko (6):
  staging: fbtft: convert fbtft_reset() to be non-atomic
  staging: fbtft: do not override DMA coherent mask
  staging: fbtft: fallback to usual allocation when DMA fails
  staging: fbtft: propagate error code from kstrto*()
  staging: fbtft: fb_ssd1306: Support smaller screen sizes
  staging: fbtft: fb_ssd1306: Refactor write_vmem()
