Good to hear it's working!
@Lucas: Yes, I don't forward the ioctl to the system and answer 0 to nickel (meaning "ioctl executed, no problems").
About the driver question, the source you mentioned gets not compiled into the kernel, the only things you can use are in mxc_epdc_fb.c
From the kernel config:
Code:
# Frame buffer hardware drivers
CONFIG_FB_MXC=y
# CONFIG_FB_MXC_SYNC_PANEL is not set
# CONFIG_FB_MXC_ASYNC_PANEL is not set
CONFIG_FB_MXC_EINK_PANEL=y
# CONFIG_FB_MXC_AUO_K1901 is not set
# CONFIG_FB_MXC_EINK_AUTO_UPDATE_MODE is not set
