This allows me to use set_pxa_fb_info and removes related issues in other parts of the code. - change the way we do setup_fb in am200epd so am200epd does not need to wait for metronomefb to receive its waveform file from user space. Thanks to Eric and Russell for feedback. I will take out DEBUG before final. This RFC consists of patches intended to improve the condition of the am200epd devkit support. The am200epd devkit contains a gumstix (pxa255) and a carrier board (am200epd or Lyre), and a metronome display controller. Previously, there was a drivers/video/am200epd driver that manipulated pxa LCDC registers and GPSR/GPLR registers directly. That was clearly wrong and broken so I have removed it and written a new mach-pxa am200epd support driver.This driver interfaces with pxafb through a set of callbacks to share/unshare pxafb's framebuffer and achieves the same functionality without manipulating any pxa registers directly. The patches are split as follows: pxafb: add shared framebuffer interface gumstix: conversion to MFP support and add bluetooth support am200epd: convert to shared fb and use gpio api metronomefb: convert printk to dev_dbg/err messages metronomefb: changes to use separate framebuffer I would be grateful for any feedback and advice.
