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 arch/arm/mach-omap2/board-n8x0.c | 42 +++++ drivers/i2c/busses/Kconfig | 10 ++ drivers/i2c/busses/Makefile | 1 + drivers/i2c/busses/i2c-cbus.c | 300 +++++++++++++++++++++++++++++++++++ drivers/input/misc/Kconfig | 10 ++ drivers/input/misc/Makefile | 1 + drivers/input/misc/retu-pwrbutton.c | 118 ++++++++++++++ drivers/mfd/Kconfig | 9 + drivers/mfd/Makefile | 1 + drivers/mfd/retu-mfd.c | 264 ++++++++++++++++++++++++++++++ drivers/watchdog/Kconfig | 12 ++ drivers/watchdog/Makefile | 1 + drivers/watchdog/retu_wdt.c | 178 +++++++++++++++++++++ include/linux/i2c-cbus.h | 27 +++ include/linux/mfd/retu.h | 22 +++ 15 files changed, 996 insertions(+), 0 deletions(-) create mode 100644 drivers/i2c/busses/i2c-cbus.c create mode 100644 drivers/input/misc/retu-pwrbutton.c create mode 100644 drivers/mfd/retu-mfd.c create mode 100644 drivers/watchdog/retu_wdt.c create mode 100644 include/linux/i2c-cbus.h create mode 100644 include/linux/mfd/retu.h -- 1.7.2.5 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
