Currently, CMD-DB names for RPMH regulators follow this format: `^(smps|ldo|bob|vs)[a-n][1-9][0-9]?$` Here, the `[a-n]` value is read from the `pmic-id` DT property, which is unique to each PMIC present on the board. Note that in this older CMD-DB name format the SPMI bus on which a particular PMIC regulator exists was not apparent from its CMD-DB name. New targets like Glymur, where we have multiple SPMI buses, overcome this limitation by following a new CMD-DB name format: `^(L|S|B)[1-9][0-9]?[A-N]_E[0-3]$` Here `[A-N]_E[0-3]` part will now be read from the `pmic-id` DT prop and it includes the SPMI bus id `[0-3]` as well. However, the PMIC ID part `[A-N]` of the CMD-DB name is now unique only to the SPMI bus that the PMIC regulator is present on. which means `L1B_E0` and `L1B_E1` are both possible CMD-DB names for two different regulator LDOs present on two different SPMI buses (bus id 0 and 1) on the same board. Note that since the new `pmic-id` DT property is a combo of PMIC ID and SPMI bus ID, so its still unique to each PMIC present on the board. Update the `pmic-id` property pattern information to reflect this change in the driver handling to support this new CMD-DB naming format while maintaining backward compatiblilty with old CMD-DB naming format which is still supported for older/existing targets.

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 reStructuredText 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.
