PiTFT 3.5" (hx8357d) does not show up as /dev/fb0 #8

Hello!

The PiTFT35R_raspbian image provided in the "easy install" procedure is working "OK" (in that the TFT panel properly display the console and the X desktop when manually started).

However, recompiling the kernel manually (for another system running a Buildroot-based system), the fbtft_device modules complains about the "adafruitrt35" being unknown; and indeed it is nowhere to be found in the source tree.

I've tried various changesets, even from before the migration to the drivers in staging, and the source for fbtft_device never ever mentioned the "adafruitrt35" variant... :-(

So, I've tried to load fbtft_device with those options:

custom=1 name=adafruitrt35 rotate=90 frequency=32000000

But to no avail. :-( I've tried various combinarions, including specifying the gpios=dc:25 but that wsa not workign either...

Would it be possible that you update the source for fbtft_device with the details for that display, please?

Regards, Yann E. MORIN.

@yann-morin-1998 this is now handled by device tree overlays in 3.18.y. you can find them here: https://github.com/adafruit/Adafruit-Pi-Kernel-o-Matic/tree/pitft
