Subject[PATCH v2 0/4] cbus/retu drivers
Date
This patch set introduces drivers for CBUS access and Retu multifunction
chip found on Nokia Internet Tablets (770, N800, N810). It would be
nice get these patches applied as the functionality of these devices is
severely lacking without Retu. E.g. watchdog support is mandatory at
least on Nokia N800, you cannot currently run the mainline kernel for
longer than ~60 seconds (there is no way to disable the watchdog).

Drivers originate from linux-omap cbus branch and have been cleaned
up/rewritten around i2c and MFD core.

Patches have been tested on top of 3.7-rc3 with Nokia N800 (watchdog
feeding works, power off shuts down the device, power button triggers
IRQs and input events).

Changes since the first version (https://lkml.org/lkml/2012/9/3/265):
- i2c-cbus:
- use devres
- improve comments
- simplify and delete redundant code
- refactoring & bug fixes on error handling
- discard "input" parameter from cbus_send_bit/data()
- retu-mfd:
- use devres
- use regmap
- retu_wdt: use devres
- retu-pwrbutton: use devres

Changes since the RFC version
(http://marc.info/?l=linux-omap&m=134618967116737&w=2):
- added DT support for getting i2c-cbus GPIO pins
- merged n8x0 board file changes into i2c-cbus patch
- corrected typo in Kconfig for MFD_RETU
- added power off functionality to retu-mfd
- added IRQ functionality to retu-mfd
- added power button key driver
- some cleanups

Aaro Koskinen (4):
i2c: introduce i2c-cbus driver
mfd: introduce retu-mfd driver
watchdog: introduce retu_wdt driver
input: misc: introduce retu-pwrbutton
