Re: Request for input regarding new driver in MFD for GPS_Bluetooth_FM controller CG2900

ok bit more of information ....
We don;t use the hciattach, instead we have our own daemon which opens
up the UART and installs the line discipline (not N_HCI, but similar
one called N_SHARED) when the hciconfig hci0 up happens or even when
/dev/radio0 (FM V4L2 device) happens or when generic GPS character
device (/dev/tigps) happens...

There is non-mailine driver which gets modified to get into mainline @
http://git.omapzoom.org/?p=kernel/omap.git;a=tree;f=drivers/misc/ti-st;h=028ff4a739d7b59b94d0c613b5ef510ff338b65d;hb=refs/heads/p-android-omap-2.6.32

feel free to have a look at it...
Yes our solution too works with BlueZ and non-exactly a MFD driver but
it is a simple platform device driver .. by looks of things the driver
can run as is for your chip too .. (except for the firmware search and
download part .. may be...).

and note when we would want to support SPI transport for the same, we
plan a SPI-TTY driver ('ala usb-serial) where-in we can install this
N_TI_WL line discipline on that /dev/ttySPI0 device, and the SPI
related stuff to be handled by the spi-tty.c which registers itself as
a tty_device and a tty_driver ....

Pavan
