rpi-update

  • 2013-09-03 (761e74acea69c2ae4d503cac8c529273babfef4c)

    • fbtft_device: Add support for Freetronics OLED128 module and Tianma TM022HDH26
    • fb_ssd1351: added chip gpio support (backlight)
    • ads7846_device: moved to notro/fbtft_tools
    • fbtft: add active low backlight pinname: 'led_'

  • 2013-08-22 (f5fda53ad421799c7266310d87045cab0b525dec)

    • All drivers have been rewritten (except flexfb). They now contain only LCD Controller specific logic and a default init sequence. fbtft_device contains the display specific information.
      Show supported displays like this sudo modprobe fbtft_device name=list; dmesg | tail -30
    • rotate argument is now a conter clockwise angle: 0, 90, 180, 270
    • All drivers support all interface modes: SPI 8-bit + D/C, 8-bit + startbyte, 9-bit, GPIO 8, 16 bit (even though the LCD controller might not).
    • The drivers will also load automatically when the device is present (need only load fbtft_device).
    • The init sequence can be overridden on all drivers with the fbtft_device init argument.

    • Issue: Sticky keys
    • Issue: 16-bit databus support is not working.
