Following are some patches for the tps6586x regulator driver that were
made in the ChromeOS repository.
A variety of people have built a kernel containing these patches, and
booted Tegra Seaboard with that kernel.
Danny Huang (4):
regulator: tps6586x: Add missing bit mask generation
regulator: tps6586x: Fix TPS6586X_DVM to store goreg/bit
regulator: tps6586x: Handle both enable reg/bits being the same
regulator: tps6586x: correct register table

In general please do try to provide a bit more detail in your changelogs
- things like missing shifts are fairly obvious but...

> regulator: tps6586x: Handle both enable reg/bits being the same
...things like these aren't obvious.
Please also note that the kernel does not use Gerritt.
