stlc45xx (the fully GPLv2 WLAN driver for N800/N810) was included to the staging tree in Linux 2.6.30. Now it’s possible to use linux-omap kernels with an in-tree WLAN driver. (Unfortunately N800/N810 support is broken in linux-omap tree currently, but that’s another story.) This means that the stlc45xx gitorious repository will be phased out and all development should happen in the staging tree instead. I just need to port the remaining patches from gitorious to the staging tree.
Also it was concluded that stlc45xx has so much in common with p54 driver that stlc45xx code should be merged with p54. Christian Lamparter and Max Filippov have merging code from stlc45xx and created a new driver called p54spi. As soon as p54spi is found to be good enough stlc45xx will be removed from the staging tree and p54spi should be used instead. I don’t know yet when this will happen.
So WLAN support is now better in mainline kernels and the next challenge is to get N800/N810 support to mainline kernels.
