Yes it is. It is a two-faced device driver. It essentially is a TTY ldisc driver which is mainly used for the transport purposes, and has the overall context of a platform device driver. > > Would it be suitable if we place the V4L2 FM driver at > > drivers/staging/ti-st/ to ?

Yes, Thanks on this one. However I am not sure how it would affect the current development of the 1273 drivers (from nokia), since the V4L2 driver which we have for 1283 - would essentially have the same sort of engine which forms the commands/interprets the responses, with the only difference being the transport (i2c vs. TTY).

WiLink 7 would be a peripheral which has 1 interface with apps processor being UART, more details at, http://www.google.co.in/url?sa=t&source=web&cd=3&ved=0CBQQFjAC&url=http%3A%2F%2Ffocus.ti.com%2Fgeneral%2Fdocs%2Fwtbu%2Fwtbuproductcontent.tsp%3FtemplateId%3D6123%26navigationId%3D12859%26contentId%3D67453%26DCMP%3Dwtbu_wilink7_2010%26HQS%3DOther%2BPR%2Bwilink7videos&ei=d7kyTKPXMoTGlQfJ-7W-Cw&usg=AFQjCNEjN2jc9TdSDWDRtWcmbZn6Szhbug&sig2=DN4gAQls9AdOeHQhlPlvjA Since there exists only 1 interface for all BT/FM and GPS cores on chip, a shared transport driver has been developed and placed at drivers/staging/ti-st/ Would it be suitable if we place the V4L2 FM driver at drivers/staging/ti-st/ to ?

The latest development tree is at branch "devel/for_v2.6.36". Note, however, that after the launch of v2.6.35, I'll create a new branch, since the merged patches will likely get different hashes upstream. So, except if you have a short timeframe to develop the driver, it is better to develop it against the Linus tree: git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git Cheers, Mauro. -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Is the WiLink 7 a platform device (i.e. an integral part of the CPU) or a separate chip that can be used with any hardware? Will the FM Radio always be controlled over a UART/TTY bus or is that specific to your development platform?

V4L2 radio drivers for TI-WL7
Hi, We have/in process of developing a V4L2 driver for the FM Radio on the Texas Instruments WiLink 7 module. For transport/communication with the chip, we intend to use the shared transport driver currently staged in mainline at drivers/staging/ti-st/. To which tree should I generate patches against? is the tree git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-2.6.git fine ? to be used with the v4l_for_2.6.35 branch ? Also, this is over the UART/TTY unlike the WL1273 i2c mfd driver... Please suggest.
