The BD71837 had a HW "feature" where changing the regulator output voltages of other regulators but bucks 1-4 might cause spikes if regulators were enabled. Thus SW prohibit voltage changes for other regulators except for bucks 1-4 when regulator is enabled. The HW colleagues did inadvertly fix this issue for BD71847 and BD71850. Remove voltage change restrictions from other PMICs but BD71837. The LDO voltage changing is still restricted. I did not yet receive answer whether there is voltage spikes to be expected for LDOs. I only know that the power-good detection for LDOs can cause false alarms if LDO voltage is changed when LDO is enabled. We might be able to work-around this by disabling the power-good monioring for the duration of the LDO voltage change - but as I said, I don't know yet. Let's fix it later if we can confirm that also LDO voltage changes are safe.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
