Mauro and the list,

This is the v7 version of the TI WL128x FM V4L2 drivers patchset.
This introduces wl128x folder under the drivers/media/radio which cater
to FM core on Texas Instrument's WL128x (also compatible with WL127x)
WiLink chipsets.
WL128x's FM can work in either Rx or Tx mode, and V4L2 interfaces are
provided for both.

** patch description **

Texas Instrument's WL128x chipset packs BT, FM, GPS and WLAN in a single
die with BT, FM and GPS being interfaced over a single UART.
This driver works on top of the shared transport line discipline driver.
This driver can also be made use for the WL127x version of the chip which packs
BT, FM and WLAN only.

Comments on the last version of the patches have been taken care,
such as,
- Now using the v4l2 control framework to support all the v4l2 controls.
- re-arranged the error handling in IRQ handlers.

Thanks & Regards,
Manjunatha Halli
