Hello, This series enables a partial DT support for twl4030-power. The missing part is the power management scripts, as the required binding should be defined first. It however enables the complete shutdown of the processor at poweroff when booting with DT, dropping the power consumption from around 350 mA on Overo+Tobi to about 40 mA.
The poweroff callback was tested with both DT and non-DT boots. The last two patches simplify the error path in the probe function, and fix registers relocking on error. Best regards, Florian Since v1: - use module_platform_driver() - split the refactoring of the probe function into a dedicated patch - new patch to fix registers relocking on error - rebased on mfd-next Florian Vaussard (5): mfd: twl4030-power: Split from twl-core into a dedicated module mfd: twl4030-power: Simplify probing of power scripts and resources mfd: twl4030-power: Start transition to DT mfd: twl4030-power: Simplify error path mfd: twl4030-power: Fix relocking on error .../devicetree/bindings/mfd/twl4030-power.txt | 28 ++++ drivers/mfd/twl-core.c | 12 +- drivers/mfd/twl4030-power.c | 149 ++++++++++++++----- include/linux/i2c/twl.h | 1 - 4 files changed, 146 insertions(+), 44 deletions(-) create mode 100644 Documentation/devicetree/bindings/mfd/twl4030-power.txt -- 1.7.5.4 _______________________________________________ devicetree-discuss mailing list devicetree-discuss@lists.ozlabs.org https://lists.ozlabs.org/listinfo/devicetree-discuss
