In an effort to cleanup this driver and add Device Tree support
the driver has been rewritten based on new driver styles and
modern kernel driver helpers. This has nearly halved the lines
of code while keeping all previous functionality.
Platform file based initialization has been dropped as there is
no examples of this use in the kernel.
v1 can be found here: [1] v2: [2] v3: [3] v4: [4] v5: [5] v6: [6] v7: [7]
Changes from v7:
- Now complies with gpiolib changes
Changes from v6:
- Removed compatible strings from DT sub-nodes
- Rearranged DT bindings
- Small fixes
Changes from v5:
- Small formatting changes to DT Docs
- Converted to_tps65912_gpio from macro to inline function
Changes from v4:
- Use mfd core to add sub-devices
Changes from v3:
- Reorganized regulator driver and related DT node
- Other small fixes as discussed in v3 thread
Changes from v2:
- Split the series further into subsystems
Changes from v1:
- Split the rewrite into delete/create patches
- Several small fixes as discussed in v1 thread

This patch adds support for TPS65912 PMIC regulators.
The regulators set consists of 4 DCDCs and 10 LDOs. The output
voltages are configurable and are meant to supply power to the
main processor and other components.

But targeted for v4.6...
But no problem really :)
I tested to merge it into my devel branch and it was supersmooth, so will

I noticed just after I'd sent this pull-request.
If it makes you feel any better you can also pull one of:
refs/tags/ib-mfd-regulator-gpio-v4.6
refs/heads/ib-mfd-regulator-gpio-4.6
... which I followed up with.
