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 |
backlight | tosa_bl/tosa_lcd | works | merged before 2.6.28-rc1. Patch for mode switching submitted | no mode switching support in mainline yet |
USB client | pxa2xx_udc | mostly works | mostly works | still can't get the RNDIS running |
MMC/SD | pxa2xx_mci | works | works | had some problems before |
Compact flash | works | works | ||
Sound | ASoC | since 2.6.27-rc1 | Must have a look in regards of ASoC v2 | |
IrDA | pxa2xx_ir | works | works | |
Touchscreen | wm97xx-ts | denoiser is flaky | no denoiser | |
LEDs | leds-tosa | works | works | |
Internal Bluetooth | tosa-bt | merged in 2.6.27-rc1 | not checked: no hw | |
WiFi | worked with 2.6.23 with linux-wlan-ng, not checked with current kernels (but should work), suspend/resume problems which may be related to OHCI problems |
