[PATCH v7 0/6] gnss: special driver for Wi2Wi w2sg0004 GPS module on GTA04 board

[H. Nikolaus Schaller]

Changes V7:
* propose a separate and dedicated driver because the w2sg0004 is quite special
* moved all code to drivers/gnss
* adapted to make use of the newly proposed gnss framework
* dropped support for w2sg0084(i) with WAKEUP feedback because that
  case is covered by the sirfstar driver
NOTE: must beapplied on top of GNSS framework

Changes V6: -- was not posted --
* worked in some feedbacks by Johan Hovold:
  risk of rfkill race, use gpiod, fix typos
* make consistent use of bool type
* factor out creation of user-space tty interface into a "gps-core"
  to make the chip driver code independent of such core features
  (originally suggested by Andrew F. Davis)

2017-12-01 08:49:41: Changes V5:
* clarified to keep it in drivers/misc and not create a new group drivers/gps
* fix formatting of new entry in omap3-gta04.dtsi (suggested by Tony Lindgren)
* removed MODULE_ALIAS (suggested by Andrew F. Davis)
* some more formatting, code&style fixes (suggested by Andrew F. Davis)
* apply __maybe_unused for PM (suggested by Andrew F. Davis)
* fixed copyright and author records (suggested by Andrew F. Davis)

2017-11-15 22:38:01: Changes V4:
* removed all pdata remains (suggested by Arnd Bergmann and Rob Herring)
* fixed minor issues and subject/commit messages (suggested by Rob Herring)
* added one missing Signed-off-By: (suggested by Andreas Färber)
* added SPDX header (suggested by Rob Herring)

2017-11-15 16:19:17: Changes V3:
* worked in suggestions by kbuild test robot
* added misc+serdev to the subject

2017-11-12 22:00:02: Changes V2:
* reduced to submit only w2sg00x4 GPS driver code
* add DT node for GTA04 device to make use of the driver
* split into base code and a debugging Kconfig option (brings device into false power state after boot)
* worked in comments by kbuild robot and Rob Herring

2017-05-21 12:44:07: RFC V1
* RFC concerning new serdev based drivers for Wi2Wi w2sg00x4 GPS module and w2cbw003 bluetooth

Years long history of getting this devices supported (original work by Neil Brown).
