Fabio:

I submitted a patch implementing this property to LKML as well, see
https://www.spinics.net/lists/kernel/msg2418471.html

All of these patches are a part of a broader attempt to add PCIe
support for i.MX7, and on that platform this is a part of a 1P0D
regulator which supplies PCIe PHY.

I can rebase this patch set to take your commit into account, or else
let's discuss the best way to allow setting ENABLE_LINREG.

Thanks,
Andrey Smirnov
