Part Driver Status Mainline Status Comments
base       basic machine definitions are in mainline
tc6393xb core tc6393xb works last fixes went before 2.6.27-rc7
NAND tmio_nand works last fixes went before 2.6.27-rc6
USB Host ohci-hcd (ohci-tmio) suspend problems, some devices simply don't work basic support merged before 2.6.28-rc1, still has some problems has problems with suspend/resume: the controller is reset and memory is cleared. Need more efforts to  create memory snapshot and securely restore it during resume. However if we don't go into real sleep, the driver suspends and resumes correctly.
Framebuffer tmiofb small issues driver support merged before 2.6.28-rc1. Currently needs small patch that provides fb data has issues with unaligned writes (they should be 16-bit aligned). Check if we can use deferred I/O to workaround this.
Keyboard tosa-keyboard works works, 2.6.25-rc1 evdev doesn't work at all with KDrive 1.3. KDrive 1.4 works, but I didn't verify the 'extended keys' support.
Keys input gpio-keys works merged ear_in merged before v2.6.27-rc7
batteries pda_power/tosa_battery works merged during 2.6.27-rc this depends on tc6393xb
