Hi,

Shouldn't the framebuffer part of this code (cfag12864bfb) also
depend on CONFIG_FB? Without that, this build error occurs:


Indeed it should. Thanks for noticing that!

cfag12864bfb.c:(.init.text+0xc19d): undefined reference to `framebuffer_alloc'
cfag12864bfb.c:(.init.text+0xc211): undefined reference to `register_framebuffer'
cfag12864bfb.c:(.text+0xf2782): undefined reference to `unregister_framebuffer'
cfag12864bfb.c:(.text+0xf2789): undefined reference to `framebuffer_release'

(from 2.6.20-rc1-mm1)

so you may need to modify the Kconfig and Makefile to have a
separate config entry for cfag12864bfb (or is it always required?).


For normal users, yes, it is the only way (yet) to use cfag12864b
(through a framebuffer). However, I divided the code in logical blocks
so it is more modular (easier understanding, scalability...), so
anyone can easily add a new way to control the LCD without worring
about other unrelated stuff the code.


And while you are there (in the Kconfig file), please change
(hertzs) to (hertz).


Thanks again.
